# LDAP Simple Authentication

The LDAP Simple Authentication module implements a very basic form of LDAP authentication. The module validates all connections (users, routes, and so on) by authenticating to the LDAP server. The authentication process uses the name and password that the application used when connecting to the EMS server.

The user name must be in the form of a distinguished name, unless a user name pattern is supplied through the `tibems.ldap.user_pattern` parameter. When a user pattern is supplied, the DN used for the lookup is that pattern string, with `%u` replaced with the name of the user.
