This is very strange, just about the only thing I would really change in 
your smb.conf is to remove these lines:

unix extensions = no
follow symlinks= yes
wide links= yes

And they cannot have anything to do with your problem.

The ID for Domain Users (when using the 'rid' backend) is calculated 
from this:

ID = RID + LOW_RANGE_ID

The RID for Domain Users is always '513' and your domain low range is 
'10000', so it becomes:

ID = 513 + 10000

So 'ID' == 10513

What packages have you installed to get Samba working on your new server ?
