When:

• Installing or upgrading SSO and executing the setup script

What:

• Setup script complains about missing Accounting Service settings (one or many errors):

  error: required parameter is missing: accounting.instancename
  error: required parameter is missing: accounting.datasource.url
  error: required parameter is missing: accounting.jms.broker.host
  error: required parameter is missing: accounting.jms.broker.port
  error: required parameter is missing: accounting.jms.broker.socket-timeout-ms

Why:

• The necessary settings have not been added to or have been deleted from the configuration file win32.config/unix.config

How to fix:

• Add the settings and modify the values according to your needs in win32.config/unix.config file as explained here and continue from the setup script again

When:

• Installing or upgrading SSO and executing install, update or remove script

What:

• Script complains about missing Java:

  ./config/tomcat/install.sh
  Creating serverhost keystore /usr/local/ubisecure/ubilogin-sso/ubilogin/custom/tomcat/keystore.pfx
  Unable to find Java

Why:

• JAVA_HOME environment variable has not been set but it is required by the Accounting Service with embedded scripts in the JAR file

How to fix:

• Add JAVA_HOME as explained here and rerun the script

When:

• After upgrade when want to view the log events

What:

• Log file is not found on the expected location

Why:

• The property name to define the log file location changed in SSO 8.7 and is now logging.file.name. Check the available settings from Accounting Service additional configuration.

How to fix:

• Fix the custom configuration file in this location: ubilogin/custom/accounting/config/application.yaml and update service by running ubilogin/config/tomcat/update script.

When:

• Starting Accounting Service for the first time after installation or restarting Accounting Service after a successful installation

What:

• Database tables cannot be created in the initial startup or database connection cannot be created when checking the migration status, the following kind of error message in the Accounting Service application log:

  15:24:36.713 [main]       ERROR Application run failed : o.s.boot.SpringApplication.reportFailure
  org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flyway'

  org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is 
  org.postgresql.util.PSQLException: FATAL: Ident authentication failed for user "accounting_user"

Why:

• Cannot connect to the PostgreSQL Database

How to fix:

• Check the root cause from the org.postgresql.util.PSQLException in the log, there are some alternatives:

org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host "127.0.0.1", 
user "accounting_user", database "accountingdb", SSL off

• • You have not configured PostgreSQL to accept connections from your host to the configured database and user, see the comment about md5 here and fix your PostgreSQL setup, start the Accounting Service again
  • You have forgotten to create the database in the PostgreSQL server, follow instructions in here, start the Accounting Service again
  • You have configured a wrong JDBC connection URL or username in the Accounting Service settings in win32.config/unix.config file, follow instructions in here (check that there are no trailing spaces in your settings)

org.postgresql.util.PSQLException: FATAL: Ident authentication failed for user "accounting_user"

• • You have not configured PostgreSQL to accept password based authentication, see the comment about md5 here and fix your PostgreSQL setup, start the Accounting Service again

org.postgresql.util.PSQLException: FATAL: password authentication failed for user "accounting_user"

• • You have configured a wrong JDBC connection password in the Accounting Service settings in win32.config/unix.config file, follow instructions in here, check especially that you don't have extra spaces or other invisible characters after the password setting
  • Note that if you have created a user name having uppercase letters these are converted to lowercase letters by PostgreSQL

org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port 
are correct and that the postmaster is accepting TCP/IP connections.

• • Your PostgreSQL RDBMS server is down, start it, start the Accounting Service again
  • You have configured a wrong JDBC connection URL host name or port in the Accounting Service settings in win32.config/unix.config file, follow instructions in here
  • You cannot connect from the server SSO with Accounting Service is running to the correctly configured URL where the PostgreSQL RDBMS server is running, fix your network topology, firewall settings etc., start the Accounting Service again

org.postgresql.util.PSQLException: FATAL: the database system is starting up

• • Your PostgreSQL RDBMS server had not yet started when Accounting Service already tried to start, start the Accounting Service again when PostgreSQL server is up

When:

• Starting Accounting Service for the first time after installation or restarting Accounting Service after a successful installation

What:

• Accounting Service reads the secret key for pseudonymisation in startup which fails, the following kind of error message in the Accounting Service application log:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2019-08-24 04:47:59.510 ERROR 53308 --- [main] o.s.boot.SpringApplication               : Application run failed

Caused by: java.io.IOException: Testing if file exists and is readable failed
        at com.ubisecure.ids.accounting.configuration.SecurityConfigurationProperties.init(SecurityConfigurationProperties.java:112)

Why:

• Accounting Service cannot access the key in the given location, see  Account Service security / Pseudonymisation

How to fix:

• Check the location from the stack trace
• NOTE that correctly set file:///usr/local/... turns into file:////usr/local/... in the log.

Invalid value for 'ubisecure.ids.accounting.security.key-location-uri' ('secret-key-location')':

• Check the root cause from the last causing exception in the stack trace, there are some alternatives

Caused by: java.io.IOException: Testing if file exists and is readable failed

• • You have configured a wrong security key location in the Accounting Service settings in win32.config/unix.config file, follow instructions in here
  • You have forgotten to set the key and put the file in place, create the file with a random key in it, start the Accounting Service again

Caused by: java.lang.IllegalArgumentException: URI has an authority component

• • When the location starts with file://usr/local/... it is not a proper file URI, turn into an absolute path by adding one / after the scheme, fix setting in the win32.config/unix.config file

Caused by: java.lang.IllegalArgumentException: Missing scheme

• • When the location starts with /usr/local/... it is not an URI, add the scheme file://, fix setting in the win32.config/unix.config file

When:

• Starting Accounting Service for the first time after installation or restarting Accounting Service after a successful installation

What:

• Accounting Service reads the secret key for pseudonymisation in startup which fails, the following kind of error message in the Accounting Service application log:

2019-08-29 15:03:44.965 ERROR 23028 --- [main] c.u.i.a.collector.DataProtector          : 
Invalid HMAC key in the key file: <secret key location>. Application will be stopped.
java.lang.IllegalArgumentException: Empty key

Why:

• You have left the file in the secret key location empty

How to fix:

• Generate a random key and store it into this file, start the Accounting Service again

When:

• Starting Accounting Service for the first time after installation or restarting Accounting Service after a successful installation

What:

• Database tables cannot be created in the initial startup, the following kind of error message in the Accounting Service application log:

15:24:36.713 [main]       WARN ConfigServletWebServerApplicationContext : Exception encountered during context initialization - 
cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer'

----------------------------------------------------------------------------------------------------------------
SQL State  : 42501
Error Code : 0
Message    : ERROR: permission denied for relation flyway_schema_history

Why:

• Database user of the PostgreSQL Database does not have sufficient permissions to create tables and rows in the Accounting Service database
• Permission to create tables is required by the Flyway migration tool

How to fix:

• Grant more roles to the database user as advised here: PostgreSQL preparation on Linux / PostgreSQL preparation on Windows
• As an alternative you may define by the means of Spring Boot configuration a different database user for Flyway access with more permissions than the regular database user

When:

• Accounting Service authorised user tries to access the browser end-points like https://accounting.example.com/accounting/report (example URL)
• Browser redirects to the SSO login page where user is supposed to authenticate with the configured authentication method to the OAuth2 application created during the installation process

What:

• Authentication succeeds but the report is not downloaded, there is this kind of [invalid_token_response] error page:
• If the respective API end-point like https://accounting.example.com/api/v1/accounting/report is requested directly 401 is returned without any response data, the following kind of error message in the Accounting Service application log:

2019-11-13 15:06:47.677 ERROR 4100 --- [http-nio-8084-exec-10] c.u.i.a.oauth2.IntrospectingJwtDecoder   :

PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path 
to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: 
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path 
to requested target

Why:

• Account Service can not complete the authentication flow as it does not trust SSO server when accessing it from server side
• SSO server is not added to the Java trust store or the owner of the certificate is not correct
• In the case above IP address has been used instead of the host name, which is not possible for the certificate subject

How to fix:

• If the certificate is missing from the Java trust store, add it by following the instructions in here, and restart Accounting Service
• If the host name in the certificate is not correct, fix settings in win32.config/unix.config file, remove the already created certificate from the installation directory before continuing with the installation

When:

• Authorised user tries to access the browser end-points like https://accounting.example.com/accounting/report (example URL)
• Browser redirects to the SSO login page where user is supposed to authenticate with the configured authentication method to the OAuth2 application created during the installation process

What:

• Authentication succeeds but SSO login page shows the following error message:
  Access to the requested resource is denied

Why:

• This user is not allowed to use the Accounting OAuth2 application in SSO, see Accounting Service installation about the Accounting application

How to fix:

• Use a different user account or configure this user to be a member of Accounting Users in SSO

When:

• Authorised user tries to access the browser end-points like https://accounting.example.com/accounting/report (example URL)

What:

• SSO login page shows the following error message:
  The requested application was not found
  

Why:

• The OAuth2 client credentials in Accounting Service and the Accounting OAuth2 application in SSO do not match or the application in SSO has been deleted, see finalise Accounting Service installation about the Accounting application
• The application and client credentials are automatically created and configured on both sides during SSO installation
• Installation has not been properly executed or the related configuration has been manually changed afterwards

How to fix:

• Install Ubisecure SSO and Accounting Service again

When:

• Accounting Service authorised user tries to access the browser end-points like https://accounting.example.com/accounting/report (example URL)

• Browser redirects to the SSO login page where user is supposed to authenticate with the configured authentication method to the OAuth2 application created during the installation process

What:

• Authentication succeeds but the report is not downloaded, there is this kind of [invalid_redirect_uri_parameter] error page:

  or this kind of [Invalid credentials] error page:

Why:

• Behind a proxy OAuth2 redirection requires a link to the proxy and not to the physical address of the machine hosting your application
  • The property name to define the log file location changed in SSO 8.7 and is now server.forward-headers-strategy which you may have missed when doing upgrade
• Account Service redirect URI needs to be exactly the same in the browser and in the configuration
• Browsers tend to change an uppercase hostname to lowercase and checking on Spring framework side is case sensitive

How to fix:

• In case of proxy check that you have not overridden or removed server.forward-headers-strategy (earlier server.use-forward-headers) setting in Accounting Service additional configuration and configured your reverse proxy / load balancer to send X-Forwarded-For and X-Forwarded-Proto headers
  • Fix the custom configuration file in this location: ubilogin/custom/accounting/config/application.yaml and update service by running ubilogin/config/tomcat/update script.
• Check that access URL (in lowercase) matches with accounting.url setting in win32.config/unix.config file, and that the network configuration supports this properly

When:

• Accounting Service authorised user tries to access the browser end-points like https://accounting.example.com/accounting/report (example URL)

• Browser redirects to the SSO login page where user is supposed to authenticate with the configured authentication method to the OAuth2 application created during the installation process

What:

• Authentication succeeds but the report is not downloaded, there is this kind of [authorization_request_not_found] error page:

Why:

• Account Service can not complete the authentication flow as the session cookie (JSESSIONID) has expired or does not have a matching hostname
• Spring framework creates the session cookie with the hostname from the original request URL and tries to find the cookie with the hostname in the redirect URL and if they differ the problem occurs

How to fix:

• Session expires by default in 10 minutes, try again if the error persists
• Check that access URL matches with accounting.url setting in win32.config/unix.config file, and that the network configuration supports this properly

When:

• Accounting Service authorised user tries to access the browser end-points like https://accounting.example.com/accounting/report (example URL)

• Browser redirects to the SSO login page where user is supposed to authenticate with the configured authentication method to the OAuth2 application created during the installation process

What:

• Authentication succeeds but the report is not downloaded, there is this kind of [invalid_grant] "Authorization code is not valid" error page:

Why:

• In a clustered environment OAuth2 flow starts with one SSO server node but once SSO session is created the flow continues on another SSO server node which is not aware of the existing SSO session and rejects the authorization code
• You must configure either active-passive setup or use Redis as session storage for your cluster

How to fix:

• Fix clustered SSO configuration like explained here SSO Cluster installation
• With IIS, check the SSO server load balancing and server affinity for sticky sessions, you need to have different client cookie name for different server farms, it is a good idea to restart your site after the configuration has been changed
• As a temporary solution you can try several times and may succeed, or you can disable all but one SSO node in order to get the report you need. However, note that incorrect cluster configuration may also affect your customers in regular SSO usage.

When:

• Accounting Service authorised user tries to access the browser end-points like https://accounting.example.com/accounting/report (example URL)

What:

• Authentication succeeds and a CSV file is returned but it is empty or contains an error message, when each CSV file should have at least a header row

• Error example:

  <html>
    <head>
      <title>404 Not Found</title>
    </head>
    <body>
      <div>
        <h2>404 Not Found</h2>
      </div>
    </body>
  </html>

Why:

• Accounting Service uses its own API to provide the actual result but accessing the API through the public address fails

How to fix:

• In case of the example above configure your load balancer / reverse proxy to allow access to the /api/* paths as advised here Installation requirements / Network requirements.
• See also section Troubleshooting Accounting Service - SSO#Empty events CSV due OAuth2 cookie / configuration error below for an other kind of error situation.

When:

• Accounting Service authorised user tries to access the browser end-points like https://accounting.example.com/accounting/report (example URL)

What:

• Authentication succeeds and a CSV file is returned but it is empty, when each CSV file should have at least a header row

• There is a following kind of error message in the Accounting Service application log:

Why:

• Accounting Service uses its own API to provide the actual result but accessing the API through the public address fails because of certificate with Accounting DNS name is not present: "No subject alternative DNS name matching accounting.ids-centos7.localdomain found"

How to fix:

• Add certificate to the trust store e.g. by including the configured DNS (hostname from accounting.url in win32.config/unix.config) as a Subject Alt Name, see Add Server Certificate to Java Trust Store
• See also section Troubleshooting Accounting Service - SSO#Empty events CSV due OAuth2 cookie / configuration error below for an other kind of error situation.

When:

• Accounting Service is trying to initialise the secret key for pseudonymisation by reading it from the given location on the first 15 minutes of each month

What:

• Refreshing secret key (HMAC key) fails, the following kind of error messages in the Accounting Service application log:

  2019-08-01 00:00:00.242 ERROR 416 --- [scheduling-1] c.u.i.a.collector.DataProtector          : 
  HMAC key could not be read from the key file and events cannot be stored. Service is not stopped but the system setup and 
  key file in location: <secret key location> should be checked and fixed. 
  java.nio.file.NoSuchFileException: <secret key file name>
  
  
  2019-08-01 00:00:00.691 ERROR 416 --- [scheduling-1] c.u.i.a.collector.DataProtector          : 
  Invalid HMAC key in the key file and events cannot be stored. Service is not stopped but the key file in 
  location: <secret key location> should be checked and fixed.
  java.lang.IllegalArgumentException: Empty key

Why:

• The Accounting Service would not have started if you had a faulty key location or contents after the installation

• You have accidentally either prevented access to the network resource or file, removed the file in the given location, or corrupted (emptied) its contents later, which is notified when the service tries to read the key again in the turn of the month

How to fix:

• If the configured accounting.secret-key-location-uri is correct make the location available and have a random key present

• The system will use the previous valid key up to the next time slot it tries to refresh the key

• If you realise that accounting.secret-key-location-uri should be changed, fix setting in the win32.config/unix.config file

• In normal case the job writes to the application log:

  2019-08-01 00:00:01.684  INFO 416 --- [scheduling-1] c.u.i.a.collector.DataProtector          : 
  Successfully initialised MAC provider with algorithm: HmacSHA256 and key of length: 32.

When:

• In a clustered environment calculator or cleaner scheduler job is executing

What:

• There are these kind of error messages in the Accounting Service application log on some of the nodes:

  Calculator job:
  2019-08-29 03:00:02.526  WARN 10644 --- [scheduling-1] c.u.i.a.calculator.AccountingCalculator  : 
  Failed to create Daily Accounting entities for day: 2019-08-28 because: 'could not execute statement; SQL [n/a]; 
  nested exception is org.hibernate.exception.LockAcquisitionException: could not execute statement'. 
  Check the 'calculationSchedule' configuration property for all running instances of this application.
  
  
  Cleaner job:
  2019-08-29 04:00:01.507 ERROR 15968 --- [scheduling-1] o.s.s.s.TaskUtils$LoggingErrorHandler    : Unexpected error occurred in scheduled task.
  org.springframework.orm.ObjectOptimisticLockingFailureException: Batch update returned unexpected row count from update [0]; 
  actual row count: 0; expected: 1; nested exception is...

Why:

• You have forgotten to specify a different execution time for the scheduled jobs on different nodes

How to fix:

• Check and fix calculation-schedule and cleaner-schedule on different nodes, follow instructions here, and restart Accounting Service
• These warnings and errors are not critical as we never count daily events twice, and it does not matter if we try to delete something that is not existing anymore, but you get rid of unnecessary noise in the logs

• When the jobs run normally they write to the application log:

  2019-08-29 03:00:00.162  INFO 82497 --- [scheduling-1] c.u.i.a.calculator.AccountingCalculator  :
