[Dovecot] Dovecot 1.0-test52 and LDAP authentication

[Jonathan Salomon]

Hi all!

I have upgraded Dovecot 0.99.11 installation that's worked with LDAP to
Dovecot 1.0-test52 and I can't get LDAP to work. I noticed the
/etc/dovecot.conf is slightly different, so I have adjusted changes. If I
use the standard auth (passw & pam) everything works fine, however when I
user ldap for auth Dovecot starts but then dies:

dovecot: Nov 26 14:14:36 Error: Auth process died too early - shutting
down dovecot: Nov 26 14:14:36 Error: child 16454 (auth) killed with signal
11

As far as I can tell the /etc/dovecot-ldap.conf hasn't changed since
0.99.11 and the LDAP server is working properly. What is happening here?

I did a 'strace -f dovecot 2>log' because I saw this in the mailing list
archive, but it doesn't really tell me anything, so I have someone can
tell me what is happening here. I have included the tail below.

Thank you in advance!
Jonathan
