RE [Samba] root != admin domain user?

Tue Oct 23 11:46:51 GMT 2007

Hi,

I read the whole chapter and found the magic words :-)

---
To obtain the domain SID on a Samba domain controller, run the following 
command:

|root# | net getlocalsid
SID for domain FOO is: S-1-5-21-4294955119-3368514841-2087710299

You may assign the domain administrator RID to an account using the 
|pdbedit| command as shown here:

|root# | pdbedit -U S-1-5-21-4294955119-3368514841-2087710299-500 -u root -r

---

Only the first command runs properly on my site...

The second one fails (yes, I changed it to use our domain SID :P ):
---
build_sam_pass: Failing attempt to store user with non-uid based user RID.
smbpasswd_update_sam_account: build_smb_pass failed!
Unable to modify entry!
---

google doesn't tell me much...
A "similar" problem has been posted here: 
http://lists.samba.org/archive/samba/2007-April/131104.html but it seems 
that Mauricio Silveira never got an answer...

@ Mauricio: if you found a solution please post! :-)

Any (more) ideas?

Cheers,
Martin
