I could then select this attribute in the "Password Never Expires Users" Report under Password Reports.

Now that I have purchased ADManager Plus, it won't let me create the attribute in my new installation of ADManager Plus.  It says the attribute is already in use however I cannot select this attribute in the "Password Never Expires Users" built-in report.

I need this attribute so that I can see when these users have actually logged in.

I have also tried lastLogonTimeStamp with no luck as I get the same error.

Please help!
