If you want to edit the domain names / groups synchronized with Letsignit, follow the steps below :

2. A window with two sections appears. Click on the "Domain" tab.

Once in this section, you can see the all list of the domain names of your Active Directory.
You can untick those you don't want to synchronize into your Letsignit platform.

You can also choose whether or not to synchronize inactive users in your corporate directory by selecting the option in your synchronization panel.

NB: Domain names present in the groups you synchronize must be ticked in the “by domains” section. Otherwise, users in these groups with these domain names will not be synchronized on your platform.
