I have a SingleSignOn solution in place from 1 domain to the other.

It is done by a silverlight app which sends an authenticated request to my other domain.

The problem I have is that when I go to the silverlight page, when I'm not logged on to the second domain yet, the SSO is done and I'm logged in to the second domain without any problem.

When I then, DON't log out, but perform the SSO again, I'm getting a 401 Not authorized error on my crossdomain.xml file..

Anyone encountered a similar problem and knows whats going on?

Will provide extra info if needed, Thanks

Apparently the issue was that only anonymous access to the file was allowed. Setting <location> <allow =? and =* did not help.

The fix was to add Everyone to the permissions of the file and give them read access.
