As per the documentation, we have to change the solMan user name in the cryptoClient.properties files -
-------------------------
Prerequisites for SAML Configuration
1 After installing the EI extension into HP ALM, stop the HP ALM server.
2 In C:\ProgramData\HP\ALM\jboss\server\default\deploy\, rename the EIServer.war file to EIServer.rar and open the archive.
3 Extract the files into a new folder named EIServer.war (in the ALM folder mentioned above).
4 Keep the .rar file as a backup outside of the ALM folder.
5 Enter the Solution Manager username for authentication into your HP
configuration file. The file is located in C:\ProgramData\HP\ALM\jboss\server\default\deploy\EIServer.war\
WEB-INF\classes\cryptoClient.properties. Change the temporary value for solman.user to the name of the user you want to use for authentication.
6 Restart your HP ALM server.
-------------------------
I did change the solman user id but after restarting ALM server, the temporary value (solman.user) retained.
I don't know how to change this value. Is anybody faced this issue before?
