Description Jeff Layton 2008-02-05 16:57:11 UTC
Currently, CIFS lacks the ability to map windows users to Linux users and vice
versa. This means that CIFS mounts are single-user unless posix extensions are
enabled. If they are enabled, then we rely on the (likely wrong) assumption that
uids and gids are mapped identically on the client and server.

To fix this, we need to be able to query userspace for this info, probably via a
daemon that talks to winbind. So we need to add support for idmap upcalls to
CIFS. We'll also need userspace support for this, but that's really a separate
project.

Comment 1 Bug Zapper 2008-05-14 05:00:31 UTC
Changing version to '9' as part of upcoming Fedora 9 GA.

Comment 2 Bug Zapper 2009-06-09 23:30:00 UTC
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Comment 3 Bug Zapper 2009-11-16 08:01:12 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Comment 4 Jeff Layton 2010-01-13 13:50:22 UTC
Closing this bug for now. I'm in the process of designing a better solution upstream, so I'll pursue this there for now...
