AsyncOS also uses a query to determine if a user is a member of a directory group and a separate query 
to find all members of a group. Membership in a directory group membership determines the user’s 
permissions within the system. When you enable external authentication on the Management 
Appliance > System Administration > Users page in the GUI (or 

userconfig

 in the CLI), you assign 

user roles to the groups in your LDAP directory. User roles determine the permissions that users have in 
the system, and for externally authenticated users, the roles are assigned to directory groups instead of 
individual users. For example, you can assign users in the IT directory group the Administrator role and 
users in the Support directory group to the Help Desk User role. 

If a user belongs to multiple LDAP groups with different user roles, AsyncOS grants the user the 
permissions for the most restrictive role. For example, if a user belongs to a group with Operator 
permissions and a group with Help Desk User permissions, AsyncOS grants the user the permissions for 
the Help Desk User role.

When you configure the LDAP profile to query for group membership, enter the base DN for the 
directory level where group records can be found, the attribute that holds the group member’s user name, 
and the attribute that contains the group name. Based on the server type that you select for your LDAP 
server profile, AsyncOS enters default values for the user name and group name attributes, as well 
default query strings.

For Active Directory servers, the default query string to determine if a user is a member of a group is 
(&(objectClass=group)(member={u})). However, if your LDAP schema uses distinguished names in the 
“memberof” list instead of user names, you can use {dn} instead of {u}.
