[Samba] vampire: account mapping strangeness

[Mark Roach]

I am testing samba 3.0's net rpc vampire tool and am getting strange
results... after I import the account info, the samba usernames seem to
be mapping to hardcoded unix uid #'s instead of account names. For
example:

# pdbedit -u jah000
idmap uid range missing or invalid
idmap will be unable to map foreign SIDs
idmap gid range missing or invalid
idmap will be unable to map foreign SIDs
jah000:4:TNCorp - Heyer, Jeff A.

# getent passwd jah000
jah000:x:1003:100::/home/jah000:/bin/bash

why is jah000's account in the pdb linked to uid 4? I'm guessing that it
has something to do with the idmap stuff, but I'm not sure where to go
from here... any thoughts? 

Thanks,
