hi, I testing around with Kolab with LDAP and have some strange problems, with the auto generated packages for Wheezy.
On my first test VM, I have 2:2.2.16~rc1-1~auto+4 installed, and everything
works as expected. On a new VM I have 2.2.16-1~auto+13_amd64.deb packages and
if I include LDAP backend, I get a segmentation fault on /usr/lib/dovecot/auth:
root@kolab:/etc/dovecot/conf.d# /usr/lib/dovecot/auth
Segmentation fault
with auto+12 and auto+13
If I downgrade to auto+11 or auto+10 I get:

Then I copied from my first VM the libauthdb_ldap.so file on the new test VM to
/usr/lib/dovecot/modules/auth/libauthdb_ldap.so (remember: ~rc1-1~auto+4) and
the result:

So, it seems, that there is something broken with the autogenerated packages,
or with my fresh installed Wheey VM (KVM AMD64) in combination with LDAP.
any suggestions?
