Hi, i would like to know if anybody have implemented the authentication of dovecot against samba4 via secure ldap (SSL/TLS). I made it but in plain text through dovecot?s offical page: wiki2.dovecot.org/AuthDatabase/LDAP/AuthBinds wiki2.dovecot.org/AuthDatabase/LDAP But when i try to do it in a secure way i can?t make it work. Samba4 is listening by port 636 and dovecot is speaking by 389 or 636, but they can?t comunicate themself. I?m wondering if any of you have done this before or have any clue that might help me. Thanks.
