In the LDAP Import User Groups dialog box, select the checkbox for each group that you want to import into the SonicWALL, and then click Save.
Having user groups on the SonicWALL with the same name as existing LDAP/AD user groups allows SonicWALL group memberships and privileges to be granted upon successful LDAP authentication.
Alternatively, you can manually create user groups on the LDAP/AD server with the same names as SonicWALL
The SonicWALL appliance can retrieve group memberships efficiently in the case of Active Directory by taking advantage of its unique trait of returning a ‘memberOf’ attribute for a user.
