Configuring External LDAP Authentication for Users
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.

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.
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 username,
and the attribute that contains the group name. Based on the server type that you select for your LDAP
server profile, AysncOS enters default values for the username and group name attributes, as well default
query strings.

Note
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 usernames, you can use
{dn}
instead of
