Warning

The following instructions should not be utilised. There remains a potential of data loss during these upgrade instructions. Customers are requested to follow these upgrade instructions which require a service break.

Note

NOTE: If the solution contains additional components UbiloginCertAP and/or UbiloginWSIDP it is recommended to stop these services prior stopping the Ubiloginserver service whenever stated in the step list. UbiloginCertAP and UbiloginWSIDP services can be started after starting the Ubiloginserver service.

SSO Cluster

The diagram below describes an SSO cluster configuration to be updated.

High availability is achieved by using two SSO instances so that there is one active SSO node, and another, passive, as high availability option if another SSO node is not available. A reverse proxy is used to switch the traffic in case of failures. In case of high-performance setup, the traffic load can be distributed between both SSO nodes by the reverse proxy.

Note that LDAP content is replicated between the SSO instances, but both SSO nodes use their own LDAP (LDAPs can be installed also on their own nodes).

A reverse proxy is configured to use primarily SSO 1 node, and SSO 2 node only when SSO 1 node is not available. During the update operation, the reverse proxy is used to switch traffic away from an SSO node that is being updated while the other SSO node is still operational.

Clustered SSO Update

Update Procedure Overview

...

  1. Find out which SSO node is the schema master
    1. Use the Active Directory Schema snap-in to connect an AD LDS instance
    2. Identify the schema master
  2. Configure the reverse proxy server to route the production traffic only to the SSO 2 node
    1. Setup both SSO nodes for the activity test
    2. Optional: Test through the reverse proxy server which SSO node is active
    3. Disable traffic from the reverse proxy server to the SSO 1 node
    4. Test through the reverse proxy server which SSO node is active
  3. Disable the replication
    1. Stop the Ubiloginserver process from the SSO 1 node
    2. Disable outbound and inbound replication from the SSO 2 node
    3. Disable outbound and inbound replication from the SSO 1 node
  4. Configure the metadata clean up for the retired AD LDS instances in the SSO 1 node
    1. Clean up the metadata from the SSO 1 node using the dsmgmt tool
    2. Remove the SSO 2 node server object from the SSO 1 node using the ADSI Edit tool 
  5. Update the SSO 1 node
    1. Use document: Upgrade on Windows - SSO
    2. Test the functionality of the updated SSO 1 node
  6. Configure Proxy to route production traffic only to SSO 1 Server
    1. Route the traffic towards the SSO 1 node
    2. Optional: Export session information from the SSO 2 node's directory and import to SSO 1 node's directory
    3. Setup SSO 1 node for the activity test
    4. Test through the reverse proxy server which SSO node is active
  7. Remove the AD LDS (UbiloginDirectory) from the SSO 2 node
    1. Stop SSO and Accounting Service Windows services
    2. Stop an remove the AD LDS from the SSO 2 node
  8. Enable the replication in the SSO 1 node
  9. Update the SSO 2 node
    1. Install Java to the SSO 2 node according to the System Recommendations and Supported Platforms
    2. Execute the steps in the document  AD LDS clustering setup (node 2) - SSO
    3. Install the new SSO version to the SSO 2 node
    4. Update Tomcat configuration by reinstalling it to the SSO 2 node
    5. Check Single node installation finalization
    6. Test the functionality of the updated SSO 2 node
  10. Enable traffic from the Reverse Proxy to route production traffic to SSO 2 node in addition to the SSO 1 node

File - Add/Remove Snap-in...


Available snap-ins - Active Directory Schema - Add - OK


Active Directory Schema - Change Active Directory Domain Controller (Do not mind the possible connection error).

...

      b.   Identify the schema master

Active Directory Schema - Operations Master


Verify the schema master and click the close button.

...

      a.  Execute the steps in the document: Upgrade on Windows - SSO

      b.  Test the functionality of the updated SSO 1 node. This might require separate reverse proxy server configuration. This should be planned considering the customer's application and network setup.

...

      c. Install the new SSO version to the SSO 2 node.

         Copy the Ubisecure SSO configurations from the SSO 1 node to the SSO 2 node.

    • In practice, this means that the SSO installation folder (C:\Program Files\ubisecure\ubilogin-sso) is copied as such
    • Check the win32.config file's parameter ldap.url to see if the LDAP has been installed in the localhost. If the directory (LDAP) connection is something else than "localhost" (LDAPs are installed on their own separate nodes) then modify the C:\Program Files\ubisecure\ubilogin-sso\ubilogin\config\settings.cmd file's LDAP URL parameters on the SSO node 2. 
      1. set LDAP_URL=ldap://<IP address of the LDAP server 2>:389
      2. set LDAP_URL_HOSTNAME=<IP address of the LDAP server 2>
      3. set LDAP_URL_PORT=389

      d. Update Tomcat configuration by reinstalling it (DON’T RUN setup.cmd on SSO node 2):
