Hello Wietse.
Thank you for the help.
I found the problem to be in my dovecot config file.
Now it is working as expected.
Thanks.

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. :-(
You should follow the DEBUG_README example that uses STRACE not GDB.
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?
Postfix does not use Kerberos. LDAP uses Kerberos. Therefore,
there is no Postfix parameter for Kerberos.

Thank you.

Can anybody tell my why postmap can access my ldap data and postfix can
not?
Because you run the postmap tests as root, whereas Postfix avoids
using root privileges all the time?
To find out what operation fails, see the section on non-interactive
debuggers in http://www.postfix.org/DEBUG_README.html
