Description hawke 2008-06-23 18:38:05 EDT
Description of problem:

Version-Release number of selected component (if applicable):

How reproducible:


Steps to Reproduce:
1. Install fedora
2. Use authconfig-gtk to enable winbind auth and join a Windows domain.
3. Log in as a domain user.
4. run 'id' as the domain user.
Actual results:
winbindd hangs, requiring a SIGKILL to stop.  After doing so, 'id' returns with
a partial list of group names, and a partial list of group IDs.  At this point,
running 'id' again will return a list containing more group names but still a
couple of group IDs only.

Expected results:

winbind doesn't hang at all.  'id' gets a name for every group.

Additional info:

Same here:

[root@ls3313 ~]# rpm -qa samba\*

Before the "id" command, logging in via e.g. ssh woks, but afterwards logins just hang (I haven't checked whether they timeout after a while). I've ltraced the "id" command and it issues a number of getgrgid() calls which get dispatched to winbindd which takes very long to respond.

Do you need any other information?

Comment 4 Bug Zapper 2009-06-09 21:44:55 EDT
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bug reports from releases that are no longer maintained.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 5 Bug Zapper 2009-07-14 12:32:07 EDT
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
