Hi, I'm trying to implement the following setup.
Kerberos with LDAP-Backend. Postfix and Dovecot authenticate with Dovecot SASL against the Kerberos server. My user informations (logon, name, email, etc.) are stored in the LDAP-directory. I can logon to dovecot with gssapi over dovecot sasl without any problems. I can query fro users with the following command and get the expected result for users stored in ldap. postmap -q ccolum...@fet.at ldap:/etc/postfix/ldap-aliases.cf But when I try to send an email to any address I get the following error. Sep 19 11:56:32 hermes postfix/local[12260]: warning: dict_ldap_connect: Unable to bind to server ldap://laika.htu.tuwien.ac.at:389 with dn empty or implicit: -2 (Local error) With debuglevel = 3 in my ldap-aliases.cf I get the following log entries.
