Does DRA display the domain controller that authenticates user accounts?

Directory and Resource Administrator 6.x
fact
Directory and Resource Administrator 7.x
fact
Directory and Resource Administrator 8.0
fix
Directory and Resource Administrator (DRA) 8.0 and 7.x clients that have the Detail Pane revealed display the Last Logon Domain Controller when the logon link is selected in the Details Pane. This field only displays in the lower-right window pane when a user account is selected in Account and Resource Management. This field also displays the Last Logon Time and Logon Count.
The Last Logon by Account report in DRA Reporting also displays this information in the last default column of the report, as Authorizing DC. The Last Logon by Account report is available in the 6.x,7.x and 8.0 versions of Directory and Resource Administrator.
