adam at sogo:~$ lsb_release -a
No LSB modules are available.
Distributor ID:    Ubuntu
Description:    Ubuntu 14.04.2 LTS
Release:    14.04
Codename:    trusty

The initial Samba packages from from Ubuntu repositories, and the new 
ones come from Inverse.

I've been happy with SOGo & OpenChange until this round of upgrades (I 
wasn't using Samba then)

thx, Rowland
