crossdomain.xml 401 error when accessing site when already authenticated

crossdomain.xml 401 error when accessing site when already authenticated

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

Answer: 1

Apparently the issue was that only anonymous access to the file was allowed. Setting

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