Lightweight Directory Access Protocol (LDAP) defines a directory service structure for storing and managing information about elements in your network, such as user accounts, user groups, hosts, and servers. Several different standards exist that use LDAP to manage user accounts, groups, and permissions. Some are proprietary systems, like Microsoft Active Directory (AD), which can be managed using LDAP, or Novell eDirectory, which provides an LDAP API for managing user repository information. Others are open standards, like SAMBA, which implements LDAP standards.
In addition to RADIUS and the local user database, SonicOS supports LDAP for user authentication. It is compatible with various schemas, including Microsoft Active Directory, Novell eDirectory, and a fully configurable user-defined option that allows SonicOS to interact with any schema.
Microsoft Active Directory also works with SonicWall Single Sign-On and the SonicWall SSO Agent. For more information, see What is Single Sign-On?
