[Samba] Request for help

[NWare at ssp-uk.com]

Hi

I have a SCO Open Server system (5.0.5) running Samba 2.2.2. with shared
security. I am running pc's with win2000 installed and they can see all the
files on the share ok. However when they come to save the files the system
reports the files as being read only.
The log reports various messages the main two being:

[2003/03/04 12:35:28, 0] smbd/nttrans.c:call_nt_transact_ioctl(1762)
call_nt_transact_ioctl: Currently not implemented.
[2003/03/04 12:37:05, 0] smbd/posix_acls.c:create_canon_ace_lists(762)
create_canon_ace_lists: unable to map SID
S-1-5-21-1147943395-1069960187-114164586-132068 to uid or gid.

Would you give a pointer as to where the problem might be and how I can fix
it?

Thanks.
