Enhance Tracing for SAP HANA SSO Issues

SAP HANA will not login and authentication failures and errors. To troubleshooting any login/authentication/sso issue user need to enable tracing

Normally I enable below tracing to get the required info

ALTER SYSTEM ALTER CONFIGURATION ('indexserver.ini', 'SYSTEM') set ('trace', 'authentication') = 'debug' with reconfigure;
ALTER SYSTEM ALTER CONFIGURATION ('indexserver.ini', 'SYSTEM') set ('trace', 'crypto') = 'debug' with reconfigure;
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') set ('trace', 'authentication') = 'debug' with reconfigure;
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') set ('trace', 'xssession') = 'debug' with reconfigure;
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') set ('trace', 'xsauthentication') = 'debug' with reconfigure;

Reproduce the issue and collect the trace. After you collect all the necessary info you can run below command to disable the tracing.

ALTER SYSTEM ALTER CONFIGURATION ('indexserver.ini', 'SYSTEM') UNSET ('trace', 'authentication');
ALTER SYSTEM ALTER CONFIGURATION ('indexserver.ini', 'SYSTEM') UNSET ('trace', 'crypto');
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') UNSET ('trace', 'authentication');
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') UNSET ('trace', 'xssession');
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') UNSET ('trace', 'xsauthentication');

Hope this helps,
