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