How to set the minimum site role for users in active directory group
In the Groups – Details page, administrators can set the minimum site role for group users to apply during synchronization.
This setting does not run synchronization; it sets the minimum site role to applied to the group every time synchronization runs. When you synchronize Active Directory groups, new users are added to the site with the minimum site role. If a user already exists, the minimum site role will be applied if it gives the user more access in a site. If you don’t set a minimum site role, new users are added as Unlicensed by default.
In a site, click Groups.
On the Groups page, select a group.
Click Actions > Minimum Site Role.
Select the minimum site role, and then click Change Site Role.
