Has anybody managed to have Dovecot authenticate to Microsoft Active Directory?

I've tried to get it to work using LDAP and the following settings

dovecot.conf:

userdb = ldap /etc/dovecot-ldap.conf passdb = ldap /etc/dovecot-ldap.conf

dovecot-ldap.conf:

hosts = rdg-home.ad.rdg.ac.uk dn = cn=bind-user,cn=users,dc=rdg-home,dc=ad,dc=rdg,dc=ac,dc=uk dnpass = XXXXX ldap_version = 2 base = dc=rdg-home,dc=ad,dc=rdg,dc=ac,dc=uk user_filter = (sAMAccountName=%u) pass_filter = (sAMAccountName=%u)

I've also tried things like "(&(objectClass=sAMACcountName)(cn=%u))" to no avail. It appears to bind properly, but never finds the account, so login fails.

I've had Active Directory authentication working with Squid and with Cyrus SASL/IMAP.

Best Wishes, Chris
