Re: [K12OSN] HELP: can there be two samba servers in one domain?



Thanks Mark,

I am sort of amazed the more I look into this. As far as I can tell,
Multiple boxes running Samba really don't have a native way to share a
single backend via AD.  I'd love to be wrong about this. I am sort of
thinking out loud here, perhaps it will help me or someone else who
has this problem in the future.

I am not able to move to OpenLdap since the scope of this project =!
complete network paradigm shift at this time. The newly released FC4
Directory Server http://directory.fedora.redhat.com/wiki/Main_Page
which could be a substitute for AD someday seems too green to me.

The more I look into trying to have more than a single Samba box share
credentials with AD it looks like I have to do one of the following,
all of which seem to have _way_ too many moving parts to be reliable.

1) Hack Samba (this is beyond my meager skillset, I assume if it were
obvious someone would have scratched this itch by now)
http://www.linux-faqs.com//HOWTO/Samba-HOWTO-Collection/cfgsmarts.php

2) use someone else's hack by way of a seemingly moribund project on
Source Forge http://groups.google.com/group/linux.samba/browse_thread/thread/e9d0a4caedd67473/40b697830a6dce06?lnk=st&q=multiple+samba+ads&rnum=10&hl=en#40b697830a6dce06
following directions from here: http://www.securityfocus.com/infocus/1563

3)Or use MS Unix tools
http://www.microsoft.com/windowsserversystem/sfu/downloads/default.mspx
using these directions http://www.oo-services.com/en/articles/sso.html

Frankly, this seems like WAY to much work, just to spread a little
storage around. I'll keep looking into this, and would love to have
someone set me straight, and tell me (in an easy to follow step by
step manner :-)   )how easy this project really is.

John
