Slow Login Performance Using SSO(XIR3.0)

I've just got SSO working, but it seems to take a long time to log into infoview.

It is a new install, the system in a single domain with about 200 users. The

Enterprise server and domain controllers are not under any significant load.

Any ideas what might be the cause?

OK The most common resolution would be to add -Djcsi.kerberos.maxpacketsize=0 to the tomcat java options and restart tomcat. I probably should have verified you were using tomcat too.

The reason is that kerberos by default tries to use UDP on all requests, and fails. Then retransmits again with TCP. This setting forces TCP from the beginning for all vintela SSO clients.

Also try hitting a different SSO URL instead of InfoViewApp/logon.jsp try InfoViewApp/logon/logonService.do

I don't think the latter will do much (just saves 1 redirect)

Let us know the results.

Regards,

Tim
