Thread:Extension talk:LDAP Authentication/Authentications with ldap works but mediawiki says "bad password"

I'm trying to get LDAP Authentication (version 1.2e) working on Mediawiki 1.19.1. The wiki is installed on a Synology NAS.

The users are created in the wiki database, and the LDAP log looks like : 2012-06-21 06:32:22 nas-01 wiki: 1.2e Entering validDomain 2012-06-21 06:32:22 nas-01 wiki: 1.2e User is using a valid domain (demo). 2012-06-21 06:32:22 nas-01 wiki: 1.2e Setting domain as: demo 2012-06-21 06:32:22 nas-01 wiki: 1.2e Entering getCanonicalName 2012-06-21 06:32:22 nas-01 wiki: 1.2e Username isn't empty. 2012-06-21 06:32:22 nas-01 wiki: 1.2e Munged username: User1 2012-06-21 06:32:22 nas-01 wiki: 1.2e Entering allowPasswordChange 2012-06-21 06:32:22 nas-01 wiki: 1.2e Entering modifyUITemplate

But the wiki login allways says... Wrong Password ! Any idea ?
