problems with samba and tdbsam backend

[Rainer Traut <tr ml gmx de>]

Hi,

I'm trying to setup samba as a PDC in our small network (15 Users).
So LDAP as backend is overkill, using tdbsam instead.

While playing a little with samba I experienced problems which are not 
in el3. Maybe I'm doing something wrong, maybe someone can give me a 
helping hand...

- the useradd program does not allow $ in usernames anymore, so the PDC 
smb.conf from the el4 Admin Guide is broken, the machine add script 
fails obviously
What is the workaround for this?

- samba also fails to add the machine account to the tdb sam
I can do this by hand and add then add my machine in domain without 
problem but samba *never* writes to my tdb backend.

Here is the important part of smb.conf, in EL3 everything works fine.
It's a little funny that the smb.conf from EL4 admin guide is broken...

Thanks
Rainer
