Kolab +samba

[Sascha Schneider]

yet another question to setip kolab with samba 

I have samba and kolab alreay installed on my linux mainserver "Ubuntu Hardy 
LTS 64bit" wich should replace our windows server as a pdc in future.
I want samba to use the openldap of kolab and read some wiki an howto's on 
that but did not yet find the "best practice".
My questions:
1) is it better to use the samba of my ubuntu or install samba from openpkg
2) should I use openldap from ubuntu or openpkg
3) should I take Gosa2 wit the samba and kolab plugins?? has someone a detaild 
installation howto for that??
