Hi All,

Trying to get the ProjectTracker WCF sample going. I'm able to get a list of projects and roles, no problem, but if I try to add a Project I get the following error:

Invalid token for impersonation - it cannot be duplicated

I haven't changed anything in the config files, other than the connectionstrings...what did I miss?

Thanks in advance!

let that be a lesson to me...read previous posts before posting Smile [:)]

add
ProjectTracker.Library.Security.PTPrincipal.Logout();

before this:
ProjectTracker.Library.Security.PTPrincipal.LoadPrincipal("pm");
