From Univention Corporate Server (UCS) you need to be logged at least once on each application even though you already logged to the UCS. So where is the SSO here ? can someone tell us how to activate it ?
For someone whom may want to know.
The SSO is supported for UCS applications. However, application from the app catalog liek OX are not supported. You need a SAML authentication for any applications which need the provider procedure of the application.
