I have my asp.net web server setup to use windows authentication.
It is authenticating just fine with my current logged in user.
I can verify this by viewing ...
HttpContext.Current.User.Identity.Name
And I can verify that I am authenticated by viewing...
HttpContext.Current.User.Identity.IsAuthenticated
However, when I call the .IsInRole function I get the trust relationship error...
HttpContext.Current.User.IsInRole("accounting")
I have found online references to problems with supplying domain name with the role name (domain\accounting), but I still get the same error. Any suggestions on where to look or troubleshoot the problem?
Well, it seems that if you are referencing a Role that doesn't exist then you get the trusted domain error.
The error went away and the code functioned just fine when I changed from ...
HttpContext.Current.User.IsInRole("accounting")
to the actual group name ...
HttpContext.Current.User.IsInRole("rsi_accounting")
