Apache and SSO

Hello all,

 

We are running webtier over Apache and configured SSO trough IIS. The authentication works fine, but ESS is very very slow. Every click takes about 30 seconds to load the next page. My first question now, why is it so slow and does somebody have some tweaking instructions? Is it possible to run the Webclient/ESS with SSO without IIS, only apache in interaction with Kerberos?

 

Thank you for your help
