[Samba] Beginner problems

[Nash Computer Technology]

Hi

I hope I've posted this to the correct place.  I've installed Samba 2.2.4 on a Caldera 
Open Unix 8 server, and created a basic smbd.conf file.  When I launch smbd as a 
daemon, I'm getting the following in the log file:

passdb/secrets.c: (43)
failed to open /usr/lib/samba/private/secrets.tdb
passdb/machine_sid.c: (163)
pdb_generate_sam_sid: Failed to store generated machine SID
smbd/server.c: (793)
ERROR: Samba cannot create a SAM SID

Is it something to do with a password file???  I'd appreciate some help with this.  I'm 
new to Unix and Samba.
