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\\<username>
S-1-5-21-1117850145-XXXXXXXX-XXXXXXX-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-XXXXXXXX-XXXXXXX-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 <domain>\\<username>
<username>:*:100000:100002::/home/<domain>/<username>:/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=100000,S-1-5-21-1117850145-XXXXXXXX-XXXXXXX-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-XXXXXXXX-XXXXXXX-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
