I have a functioning Active Directory server, but whenever I try to authenticate against the Postfix server that uses it (with
saslauthd) I notice that only the bind user can connect. Whenever I try to connect to the server with valid credentials, it does not work.
Any idea as to where I can debug why only the bind user can log in? I know it's possible, because I have another setup with Postfix authenticating against LDAP with all users, but I cannot seem to figure out what the difference is between those.
