I have setup SSRS2008 on a server in DOMAIN1. Users and groups from DOMAIN1 currently can access reports as expected and in accordance to their site, folder and report permissions. This was working well for a month.
Now, I have to allow users from DOMAIN2. DOMAIN2 and DOMAIN1 are in a trust relationship. I can list DOMAIN2 users and groups in the security tabs, but they cannot get into the site, even at the top level.
The error is: User 'DOMAIN2\user' does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed.
Searching Google is useless as the dominant solution addresses the first time access problem, where using IE as administrator gets you into the site and able to start listing the first users and groups. That is not my issue. I currently do have users accessing reports, just not those in DOMAIN2.
Any help is appreciated.
