Pass-through Authentication Agent Duplicate–Status Inactive
If you’re one of the early adopters of Azure AD Pass-through Authentication, you may face a problem with a duplicate authentication agent in your Azure portal which is displaying as ‘Inactive’ in its Status. This can happen when you’re upgrading the Authentication Agent or reinstalling it because of some possible fault. You may ask, how do I remove this duplicate/inactive agent?
The answer is trivial. Don’t worry, this is a normal behaviour and the Inactive entry will be automatically removed from the portal after several days. So don’t sweat, leave it and it will go away soon.
