question on how to use obs for debian packages

[Jan Kowalsky]

Hi all,

I try to do my first steps with the open build system and have a few questions. 
Maybe sombody can help me a little further.

1. I'll try to locate the package kolab-ldap in the obs.

  here I can find it in the repository:
     http://obs.kolabsys.com:82/Kolab:/3.1/Debian_7.0/all/

  but neither
    https://obs.kolabsys.com/project/show?project=Kolab%3A3.1
  nor
    https://obs.kolabsys.com/project/show?project=Kolab%3ADevelopment

an apt-cache policy on my server gives me

# apt-cache policy kolab-ldap
kolab-ldap:
  Installiert:           (keine)
  Installationskandidat: 3.1.0-1
  Versionstabelle:
     3.1.0-1 0
        501 http://obs.kolabsys.com/Kolab:/3.1/Debian_7.0/ ./ Packages
        501 http://obs.kolabsys.com/Kolab:/Development/Debian_7.0/ ./ Packages

How can I get the package in my home-branch for modifying it?

2. Most of the packages have allready the debian specific files but not all.

e.g.:

https://obs.kolabsys.com/package/show?package=python-
ldap&project=Kolab%3ADevelopment has no debian files.

How is the debian package build on the source without debian-package 
description?

Thanks for explanation.
Jan
