[Samba] Can't add new domain members to Samba PDC

Tue Jan 18 11:30:07 GMT 2005

Dear Samba List,
I have been running a Samba PDC (Win 2000 & XP Clients) for about 1 year 
without problems. Now I find I cannot add new PCs to the domain, 
existing accounts are working fine.
It seems to be a rights issue, but I am not sure quite how to analyse it.
All attempts to add a computer account result in "unknown user or wrong 
password" (translated from German, may not be quite exact in English), 
although this user can and does login and use shares OK including those 
that have only "ntadmins" access rights.
I have,  always used this user account for this purpose and it worked in 
the past.

I am running Samba 3.0.10-1.fc2 on Fedora Core 2.

Your help would be appreciated.
