[Samba] Upgrade Novell 4.11 to Samba 3.0.7 wisdom needed

[Misty Stanley-Jones]

Has anybody done such a thing as this?  I'm looking to make this transition as 
smooth as possible.  I have the new fileserver up and running, and I'm using 
rsync to keep the Novell data current on the Samba server.  Any words of 
advice on transferring the users and groups and permissions over to the new 
server in the least painful way possible?  I have some idea that Novell uses 
LDAP so that I should be able do it somehow.  I don't want to screw this 
upgrade up, and any help would be appreciated.  I am hoping someone has 
already done it before and has written a Howto or something about it.

Thanks,
Misty
