The samba private directory may hold saved passwords used by samba to 
authenticate with LDAP.  the lock directory will hold various TBD 
files.  Some of them are caching files.  Some of the them may store 
group map information (that should be in LDAP) or idmap allocations (if 
winbind allocated unix uid's and gid's for samba accounts.)

I don't know what the Samba vers are with Suse 9.3 vs 11.3.   But you 
should definately plan on needing several hours to work out things that 
break.   I found that when going from Samba 3.0x. to 3.4.x.
