# KeyUserName

The name of the attribute to search for in the LDAP server.

When you authenticate a user in LDAP, it searches the group and its subdirectories for the user name that you provide in the action. You can specify the group in the Group configuration parameter, or in the Group action parameter in the Security or UserRead action. If the Community component finds the specified user name in this attribute, it attempts to authenticate against it with the credentials provided in the action.

NOTE: If there is more than one user with the specified user name, authentication fails.

If your LDAP server does not allow anonymous binding, you must use BaseDN and BaseDNPassword to specify the credentials of an LDAP user that has permission to perform the search.

You must also set RDNAttribute to perform LDAP authentication. If you do not set `KeyUsername`, Community does not perform a search, and it can only authenticate users within the Group directory, and not subdirectories.
