Apache 2.2 changed the way you configure LDAP authentication.
mod_auth_ldap was replaced with mod_authnz_ldap, so don’t forget to
enable the new module and disable the old one. Because I’ll always
forget, here’s the new style config.
AuthType basic AuthName "admin" AuthBasicProvider ldap AuthLDAPUrl ldap://ldap.example.com:389/ou=people,dc=example,dc=com?uid?sub AuthLDAPGroupAttributeIsDN off Require ldap-group cn=systems,ou=groups,dc=example,dc=com AuthLDAPGroupAttribute memberUid
The sections in bold are the sections I had to change from the 2.0
config.
