Local user login when connected to Active Directory

Local user login when connected to Active Directory

Hello,

I am facing an issue with the Active directory that,

I have selected "Use External users source" as Active Directory.
 And I am able to log in with the user credentials created in Active Directory.

But the issue is, I am also able to log in with Local users created in Zenon when connected to Active directory.

My Requirement is:

1. When the Zenon Machine is connected to Active Directory, only users created in Active directory should be used. If local user credentials are entered, it should not allow.

2. And when the Active directory machine is disconnected, then only Local user credentials should work for the Log in.

Please support for this.

Thanks,
Raja
