Problem

The Tomcat version in use is visible in error messages.

Solution

To hide the version number of Ubilogin SSO’s Tomcat, proceed as follows on each node in use.

Create folder
mkdir /usr/local/ubisecure/ubilogin-sso/tomcat/lib/org/apache/catalina/util/ -p
Create a file that contains the version information
vim /usr/local/ubisecure/ubilogin-sso/tomcat/lib/org/apache/catalina/util/ServerInfo.properties
server.info=Server
server.number=20.0.0
server.build=Jan 01 2020 13:33:37
Change the permissions and restart the Ubilogin SSO
chown ubilogin:ubilogin /usr/local/ubisecure/ubilogin-sso/tomcat/lib/org/apache/catalina/util/ServerInfo.properties
service ubilogin-server restart
