FusionDirectory

FusionDirectory provides a solution to daily management of data stored in an LDAP directory.

Go in Configuration and in Login and Session panel. Set:

• HTTP Header authentication: Activate
• Header name: Auth-User

Just set the Auth-User header with the attribute that carries the user login, for example $uid.
