[Samba] win98 users authenticating with Samba PDC, but accessing shares as guest

[Brian J. Murrell]

I recently migrated an NT4 PDC to Samba 2.2.2 on Debian Woody.  I used the
pwdump2 utility to dump the NT SAM so that it was suitable for Samba. 
Everything went pretty smoothly.

The issue seems to be now that although users on Windows 98 are
successfully authenticating against the Samba PDC (i.e. if I use a known
invalid account/password pair, I get an authentication error as I would
expect) all but one or two users seem to be getting bound to the
guest (nobody/nogroup) user rather than who they authenticated to the PDC
as:

# smbstatus

Samba version 2.2.3a-12.3 for Debian
Service      uid      gid      pid     machine

User1 is on Windows XP, but the rest are on Windows 98.  As you can see,
User2 successfully "binds" to her Linux uid/gid, but the rest are all
bound to the guest account uid/gid.

Any ideas why this would be?

Thanx,
