Lightweight Directory Access Protocol (LDAP) defines a directory services structure for storing and managing information about elements in your network, such as user accounts, user groups, hosts, and servers. See Using LDAP/Active Directory/eDirectory Authentication. Several different standards exist that use LDAP to manage user account, group, and permissions. Some are proprietary systems like Microsoft Active Directory which you can manage using LDAP. Some are open standards SAMBA, which are implementations of the LDAP standards. Some are proprietary systems like Novell eDirectory which provide an LDAP API for managing the user repository information.

Microsoft Active Directory also works with SonicWall Single Sign-On and the SonicWall SSO Agent. For more information, see Single Sign-On Overview.
