[Samba] access denied & Sid does not start with 'S-'.

[dnk]

Hi there.

For some reason I am getting permission denied errors on a new samba server.
I can add machines to the domain, I can login with any user id's and so on
as well. But when I try connecting to a public share, or the users home
directory, I get a user denied error.

"\\Fileserver\user is not accessible. You might not have permission to use
this network resource. Contact the administrator of this server to find out
if you have access permission."

When checking the permissions on the users home directory, i have the
following:

drwx------   3 user user

And permissions on my "public" directory is:

drwxrwxr-x 9 root users

In my log files I have:

smb.log

Connect path is '/home/dustin' for service [dustin]
  string_to_sid: Sid dustin does not start with 'S-'.
  '/home/dustin' does not exist or permission denied when connecting to
[dustin] Error was Permission denied
  Yielding connection to dustin
  create_conn_struct: Can't ChDir to new conn path /home/dustin. Error was
Permission denied
  create_conn_struct: Can't ChDir to new conn path /home/dustin. Error was
Permission denied




My SMB.conf is below, any ideas? This one is driving me insane as this
server was working when i set it up back in our office....
