Hello Wietse, thank you for your reply.
I tried to do this, but failed to get any result. Obviously debian optimized the debugging symbols out of postfix. :-( What i did now was the following. In the log /var/log/auth.log i found: Sep 19 18:53:51 hermes postfix/postmap[5385]: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Credentials cache file '/tmp/krb5cc_106' not found) As i did not have this file i symlinked /tmp/krb55cc_0 to /tmp/krb55cc_106 for the test and run the postmap command as the postfix user. /usr/sbin/postmap -q ccolum...@fet.at ldap:/etc/postfix/ldap-aliases.cf ccolumbus So the connection is possible with the postfix user. But i have no idea to set the right configuration parameters to let the postfix user have access to the kerberos credentials cache and to use the correct file. As i dont know why postfix wants to access /tmp/krb5cc_106 when there is only /tmp/krb5cc_0 present. Any hint how to do this? Thank you.
