Thread:Extension talk:LDAP Authentication/Failed to bind as

Hello, i have a problem with the LDAPAuthentication. Maybe someone can help me. The user authentication should be managed through Active Directory (Exchange 2003). The problem is users cannot login. The errorlog always says "bind failed". The passwort is definitely correct, i've also tried using encryptiontype = 'clear'. But same result. I got the Server's certificate and put into described folder: C:\openldap\sysconf\certs.pem and modified the ldap.conf. In Active Directory all users are in the default folder "Users".

Any mistakes in the config or what can cause the problem?

the following versions are installed: Mediawiki 1.16.5 PHP 5.3.5 (XAMPP) MySQL 5.5.8 (XAMPP) LDAPAuthPlugin 1.0.8.6

Localsetting - config:
