Re: [Samba] CTDB -- manually setting winbind uid with wbinfo

2012-05-08 Thread koutsane 
Hi Bob,

I was wondering if you were able to manually update/create the UID / GID
mappings with wbinfo --set-uid-mapping ?

I am also using CTDB samba and being able to manually set / update the IdMap
would save me a lot of time in a DR situation.

Thank-you and best regards,

Evan

[Samba] CTDB -- manually setting winbind uid with wbinfo

2011-05-17 Thread Bob Cregan 

Hi
We have a ctdb cluster setup as follows

ctdb version -- surprisingly difficult to determine. I think it is 
1.0.99 (dragged from a include file somewhere, I forget where exactly ). 
If anyone can tell me how to determine this proberly then I would be 
pleased to know.


samba version 3.5.8

I was hoping to be able to set the UID to SID mapping manually using the 
following procedure.


get the SID:

wbinfo -n domain\\
S-1-5-21-1117850145--XXX-220398 SID_USER (1)

Then set the SID to map to a desired UID rather than the random one chosen

[root@filer01-ph ctdb]# wbinfo 
--set-uid-mapping=198000,S-1-5-21-1117850145--XXX-220398

Could not create or modify uid to sid mapping
[root@filer01-ph ctdb]

I have tried deleting the old mapping beforehand and clearing the cache

[root@filer01-ph ctdb]# wbinfo -i \\
:*:10:12::/home//:/bin/false
[root@filer01-ph ctdb]

[root@filer01-ph ctdb]# net cache flush
[root@filer01-ph ctdb]# net cache list
[root@filer01-ph ctdb]#

[root@filer01-ph ctdb]# wbinfo 
--remove-uid-mapping=10,S-1-5-21-1117850145--XXX-220398

Could not remove uid to sid mapping
[root@filer01-ph ctdb]#

[root@filer01-ph ctdb]# wbinfo 
--set-uid-mapping=198000,S-1-5-21-1117850145--XXX-220398

Could not create or modify uid to sid mapping
[root@filer01-ph ctdb]


Is this a bug or am I misunderstanding how the SID to UID mapping works.

Relevant bits of the smb.conf are below


Thanks

Bob
