I have an SSRS issue where I'm getting The user or group name 'DOMAIN\Username' is not recognized. (rsUnknownUserName)
However the group or name I am trying to add is not the name that is shown it is one that already is in the list and has rights.
This is after attempting to add a group to the list. This used to work prior to changing from one AD Account to another. The old AD account couldn't send mail so we changed it but now we can't add groups!!
Is there any special AD permissions that account needs to be able to add users?
