This sounds like it's either an application issue or a Lotus Domino SSO issue. However I will ask some questions that may point you in the right direction. Is the application dependent on tomcats JSession? If so , when does it determine the userPrincipal? If not then it's an application issue. How is this SSO setup? Header based? cookie based? agent based session? is Tomcat responsible for connecting to the userstore to determine who the user is? This would be done via a realm. > We had 2 servers on Test region which are load balanced where 1 server is > working fine ( with another server shutdown ) , no issue with login page on > this server , while issue happening on another server. > So are you saying it works fine with 1 server and doesn't when 2 are running? Are you sure its not a load balancing issue? How does your application handle sessions? Does it replicate them?
