LDAP (Lightweight Directory Access Protocol) is an internet protocol for accessing distributed directory services. The NIOS appliance can authenticate admin accounts by verifying user names and passwords against LDAP. The NIOS appliance queries the LDAP server for the group membership information of the admin. The appliance matches the group names from the LDAP server with the admin groups in its local database. It then authorizes services and grants the admin privileges, based upon the matching admin group on the appliance. The following figure illustrates the LDAP authentication process.

• Configure at least one LDAP authentication server group. For more information, see Configuring an LDAP Server Group below.

• Define admin groups for the admins that are authenticated by the LDAP servers and specify their privileges and settings. The group names in NIOS must match the admin group names on the LDAP server. For more information about defining admin groups, see About Admin Groups.

• In the authentication policy, add the LDAP server groups and the admin groups that match those on the LDAP server. You can also designate an admin group as the default group for remote admins. NIOS assigns admins to this group when it does not find a matching group for a remote admin. For more information about configuring the policy, see Defining the Authentication Policy.
