Troubleshooting: "An Item with the Same Key Has Already Been Added" Error From Duplicate Realm Folders

Version Affected: All
 
 

Overview

When accessing the Advanced/Classic Experience, the page throws a generic Please Contact Your Administrator error if custom errors are turned on. The realm's Error and Event logs show:

Exception message: An item with the same key has already been added.

Cause

The same realm is being referenced more than once, due to duplicate realm folders under D:\SecureAuth and possibly duplicate matching entries in Internet Information Services (IIS).

Resolution

1. Go through the realm folders under D:\SecureAuth.
2. Find any realms with a duplicate SecureAuth# folder name. For example:
   SecureAuth24
   SecureAuth25
   SecureAuth25_ORG
   SecureAuth25_ORG1
   SecureAuth25_ORG2
   SecureAuth26
   In this example, the duplicates are SecureAuth25_ORG, SecureAuth25_ORG1, and SecureAuth25_ORG2.
3. Move or remove the duplicate folders, and remove any matching duplicate entries from IIS as well.

Special Considerations

Keep a temporary copy of any removed realm folders in case they need to be restored.
