commit 00c6271d5cbbfe808b81906d5be2b328e4f25b30
Author: Steven Danneman <steven.danneman at isilon.com>
Date: Mon Oct 27 23:37:55 2008 -0700
Added ability to remove id mappings in wbinfo and libwbclient.
The idmap_tdb backend already provides an interface to remove existing id
mappings. This commit plumbs that ability up through, winbindd, libwbclient,
and wbinfo.
Added new winbindd command:
WINBINDD_REMOVE_MAPPING
Added new libwbclient interfaces:
wbcRemoveUidMapping() and wbcRemoveGidMapping()
Added new wbinfo options:
--remove-uid-mapping
--remove-gid-mapping
Increased libwbclient version to 0.2
Increased winbind interface version to 20
commit 041c5cf3b5a2fba6ad49e049601b626d5b04ac3e
Author: Steven Danneman <steven.danneman at isilon.com>
Date: Mon Oct 27 23:46:44 2008 -0700
Added ability to set id mappings in wbinfo.
The two new parameters are:
--set-uid-mapping
--set-gid-mapping
These allow wbinfo to create new, or override existing id mappings in the
idmap backend. These expose the exisiting ability of libwbclient
and winbindd to do this, up through a command line utility.
