Cause

In the warning message, the highlighted text shows that there was a space character that is typed at the end of the sAMAccountName parameter in the 'Manage External Authentication' page in DPA interface.

Resolution

  1. In the DPA UI, open the User & Security > External Authentication page.
  2. Check the Identification Attribute field.
  3. Ensure that there are no spaces that are typed at the end of sAMAccountName.
