need de-newbification re: user names

[Nelson C. Garcia]

I am running Samba 2.0.7 on Linux Mandrake 7.0 as a PDC for Win NT 4.0 SP6.
My smb.conf is quoted at the bottom of this email.

Everything runs well, except that users complain that NT doesn't show their
full names like it used to (pre-PDC).
For example my locked workstation message would read "<full name> is logged
on as DOLPHIN\garcianc".  I verified that I did enter full names when I
created each user account on the Linux box.

I haven't been doing this very long. Could I have done something wrong when
I ran smbpasswd?  Did I miss a switch?

Thanks in advance.

Aloha,
Nelson Garcia
