UWL and SSO

Hi everyone,

I've created a custom AbstracPortalComponent to approve and reject work items which works okay.

At the moment the back-end system is using User Mapping but when I change it to Logon Ticket (parameters are set just fine, SSO works perfectly, all of the connection tests succeed) I'm returned this exception:

com.sap.portal.connectivity.destinations.PortalDestinationsServiceException:Could not get connection for alias XXX. Contact your system administrator.

Any ideas?

Thanks!

Regards
