[Samba] Resolution of Groups on Mac OS X 10.4.8...

[Peter]

Hi,

my Problem:

I tried to limit the disk usage for certain samba users by means of  
group quotas. But when looking at the disk free space from the client  
the quota is not honoured. So I wrote a little script trying to find  
out the quota left using the "dfree command" setting. So far  
everything is fine, but now, as soon as the script is called (I  
placed some debug output there) the groups, the user signing on via  
samba is member of, are not recognised. Calling "id" for this  
purpose, I got for my user a:

uid=1001(a) gid=1099(dummy) groups=1099(dummy)

but called from the commend line (after su s2) I got:

uid=1001(a) gid=1099(dummy) groups=1099(dummy), 1098(tmp), 1002(x),  
1001(y)

So my questions are:
How are those groups are resolved in Mac OS X? Which mechanism is  
used by samba (the default installation provided by apple) to resolve  
this???

Maybe I should ask this at apple as well, but maybe you are so kind  
to help...

Thakns a lot in advance,
Peter
