Last week our SSO AD loging stopped working. Even though there wern't any changes to our environment, the account that was using doing the Ops manager/Vsphere connection stopped working. I set up a all new account and thought everything was happy. Now, I can't seem to log in to the ops manager server with my domain credentials like we could before. If I go to the Authentication services and use the account that was setup for this I get a "No Permission" and the AD login fails when you try it, though it does pass the test. I use my own AD account, which has the same permissions in vpshere, and it appears to work. I'm a little confused as to what might be causing this since I can't seem to find any info on that "No permission" error. Any thoughts?
