We have dual stack Netweaver system. We just upgraded to SP18.
Everything in the system is fine, except for the SSO login for some users.
Sometimes the SSO works and sometimes the users have to enter their login details.
Can you tell me the reason behind this erratic behavior?
Also, can you guide me in the right direction is troubleshooting thsi issue.
Where do I look in the OS level or in Visual admin.
