Please can you post further details of your environment and how the users connect e.g. Unix, Linux, Windows system and LDAP or OS users ?What is the invalid login message ?TeamSite 5.5. users are managed unders iw-home/conf/roles directory if I remember rightly. I suggest starting with a check that the users are valid teamsite users in the configuration files (maybe they have been previously removed and this was only picked up with the restart).
One possibility is that their passwords have expired. Check the logs for the actual error message.
I am facing this weird issue where some users are not able to login to Teamsite 5.5This issue is with some users. they are getting invalid login message.Other user are able to login.This issue has started after server restart.Please assist.thanks.
