Hello list,
I recently upgraded an Ubuntu 8.04 LTS samba server to 10.04 LTS which
took the installed version of samba from version 3.0.28a to version
3.4.7. The server is an AD member using idmap-rid. I have updated the
idmap directives in the config and it mostly worked (winbind works,
Windows users can get to their shares with their correct permissions,
etc.). The only thing that got broken is the ability of our IP
security cameras to store data directly to the server through samba. I
believe this may have been caused by a change to a default setting,
such as the allowed authentication methods or possibly something like
'allow trusted domains', since these cameras are not capable of
actually joining the domain. I've looked at some of the in-between
release notes but no changes have jumped out at me.
The cameras are configured to connect to the given smb/cifs server and
share (which exists and can be mapped from Windows if you use the
right user). The share ('camshare') has share-level permissions set
such that DOMAIN\camera should have full access. I have winbind set to
use the default domain so the cameras are configured to connect as
'camera' instead of 'DOMAIN\camera' (but I've tried both anyway, to no
avail). I have checked the password on the 'camera' account repeatedly.
However you can see that something isn't right when the cameras try to
mount the share:
root@server:~# tail -f /var/log/samba/log.smbd | grep camera
check_ntlm_password: Authentication for user [camera] -> [camera]
FAILED with error NT_STATUS_NO_SUCH_USER
check_ntlm_password: Authentication for user [camera] -> [camera]
FAILED with error NT_STATUS_NO_SUCH_USER
check_ntlm_password: Authentication for user [camera] -> [camera]
FAILED with error NT_STATUS_NO_SUCH_USER
If I use that username with the password when mapping the share from
Win7, it works and the correct permissions are there.

I've left off some other shares that don't seem relevant.
I can provide other info and or more logs if needed. Thanks in advance

Mark,
Try adding the parameter "map untrusted to domain = Yes"
map untrusted to domain (G)
If a client connects to smbd using an untrusted domain name, such as
BOGUS\user, smbd replaces the BOGUS domain with it's SAM name before
attempting to authenticate that user. In the case where smbd is
acting as a PDC this will be DOMAIN\user. In the case where smbd is
acting as a domain member server or a standalone server this will be
WORKSTATION\user.
In previous versions of Samba (pre 3.4), if smbd was acting as a
domain member server, the BOGUS domain name would instead be
replaced by the primary domain which smbd was a member of. In this
case authentication would be deferred off to a DC using the
credentials DOMAIN\user.
When this parameter is set to |yes| smbd provides the legacy
behavior of mapping untrusted domain names to the primary domain.
When smbd is not acting as a domain member server, this parameter
has no effect.
Default: //|map untrusted to domain|/ = |no| /
