I hope someone can help with this.
Due to the decommissioning of the DC used for authentication by the plug-in, I have modified the list of DCs used. The issue is, as soon as the old DC is shut down, users are no longer able to log in! This is despite the new addresses of 2 DCs being entered into the 'Domain Controllers' tab of the plugin and the changes being saved correctly. How is the plug-in still referencing our old DC? Stumped!
Any feedback welcomed.
