[Samba] Can't add machine account with 3.0.0; ldapsam backend
Hi,
Please cc me on any replies as I'm not subscribed.
First, I've seen reference to this problem on the list but no solution, eg.:
http://marc.theaimsgroup.com/?l=samba&m=106032316504352&w=2
Platform is:
# uname -a
Linux allanon 2.4.21-xfs-aihplc3 #1 SMP Thu Aug 21 15:50:27 BST 2003
i686 unknown
Debian woody. Samba is 3.0.0final-1 from Debian unstable complied for
woody. Some other non-woody backports such as OpenLDAP, libacl, etc.
I was using beta1 previously which didn't have this problem, ie., I
could join machines to the domain, both win(NT|2k) and Linux, by
providing appropriate credentials without first adding a system account.
Config and -D 10 debug output attached.
So, adding a machine account from the samba 3.0.0 PDC machine using
pdbedit gives:
# pdbedit -v -a -m -u tardis
ldapsam_modify_entry: Failed to add user dn=
uid=tardis$,ou=Machines,dc=amazing-internet,dc=net with: Object class
violation
object class 'sambaSamAccount' requires attribute
'sambaSID'
ldapsam_add_sam_account: failed to modify/add user with uid = tardis$
(dn = uid=tardis$,ou=Machines,dc=amazing-internet,dc=net)
Unable to add machine! (does it already exist?)
And using net join on a Linux box not in the domain, tardis, gives:
# net join -S allanon -U admin -d 3

net join -d 10 output available directly on request - it's 180Kb.
I'm at a loss to explain this. It worked prior to the upgrade. Any ideas?
