Description Volkmar Glauche 2008-02-14 13:59:45 UTC

I have name service switch configured to use both files and LDAP for passwd and group database. Group lookup fails for users that are only in /etc/passwd, but not in LDAP:
* User vglauche (only in LDAP)
# id vglauche
uid=606(vglauche) gid=100(users) groups=100(users),2005(recovery),2010(spm-kurs),2011(stn_op_mrt),2017(als)
* User firebird (only in /etc/passwd)
# id firebird
uid=450(firebird) gid=450(firebird)id: failed to get groups for user `firebird': No such file or directory



Reproducible: Always

I can confirm this issue on sys-apps/coreutils-6.10-r1. It does not occur on sys-apps/coreutils-6.9-r1.

Comment 4 Volkmar Glauche 2008-02-15 07:30:52 UTC

This bug has already been noticed upstream:

http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/12375

Increasing severity - this bug prevents emerging any package that depends on id to check whether a certain user/group exists.

bug severity is irrelevant ... i'm not going to code any fixes, just wait for upstream to fix it and i'll merge those changes

bug #210975 can reproduce this with:
passwd: files winbind

so it's anything with multi look ups.

But I had a feeling it would be based on the e-mail on the ML.

added fixes from upstream to 6.10-r2

Comment 9 Nahor 2008-04-22 16:52:15 UTC

For me it happens also for users that are in both passwd and ldap. It also depends on what parameters are passed to "id" and sometimes, there is no error but still an incorrect result:

(as root):
> # id
> uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),
> 10(wheel),11(floppy),20(dialout),26(tape),27(video)
> # id root
> uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm)
> # id <user>
> uid=1001(<user>) gid=100(users)id: failed to get groups for user `<user>': No
> such file or directory
> # su - <user>
> $ id
> uid=1001(<user>) gid=100(users) groups=10(wheel),50(cvs),100(users)


Otherwise, I confirm that sys-apps/coreutils-6.10-r2 fixes the problem.
I don't think 6.10-r1 should have been marked stable with such a bug.
