Hi Folks,

I've fresh installed CentOS 5.5 and realized, that Samba is in version 
Is it possible to conect WIN7 in a Samba-Domäne with this version?
And I've read abaut RHEL 5.6 with samba 3.5.4.
Can I expect, that  this version is included in CentOS 5.6?
And can I get this version with yum-update?
