http://xi.rename-it.nl 2.2.16-1~auto+10/11/12/13: segfault /var/lib/dovecot/auth OR (db_ldap_connect_delayed):

[Denny Fuchs]

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:

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?

[Dovecot] Compile Metadata for 2.2.9

[Denny Fuchs]

hi,

I use Debian Wheezy backports for Dovecot  and I want to compile the latest 
metadata plugin, but it fails:

the metadata plugin was downloaded via: 
http://hg.dovecot.org/dovecot-metadata-plugin/archive/tip.tar.gz

I tried also hg clone ..., but got the same ...

Do I need Dovecot 2.2.10 to compile successful ?

I want to test a Kolab setup, first for private use, later also in the 
university

I thought, it is plugin, so I tried to find it on the disk ... but nothing 
found on the Debian (regular Wheezy packages)
