Defined in:
lib/jss/api_object/ldap_server.rb,
lib/jss.rb

Overview

An LDAP server in the JSS.

This class doesn’t curretly provide creation or updaing of LDAP server definitions in the JSS. Please use the JSS web UI.

However, it does provide methods for querying users and usergroups from LDAP servers, and checking group membership.

The class methods LDAPServer.user_in_ldap? and LDAPServer.group_in_ldap? can be used to check all defined LDAP servers for a user or group. They are used by Scopable::Scope when adding user and groups to scope limitations and exceptions.

Within an LDAPServer instance, the methods #find_user and #find_group will return all matches in the server for a given search term.
