Description Jim Meyering 2008-01-23 22:05:59 UTC

Description of problem: getgrent mistakenly sets errno upon EOF
when /etc/nsswitch.conf has e.g., group: nisplus


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


How reproducible: every time


Steps to Reproduce:set "group: nisplus" in /etc/nsswitch.conf
1.run "./id root", where id comes from unmodified upstream coreutils-6.10
2.note the diagnostic
3.
  
Actual results:
./id root
uid=0(root) gid=0./id: failed to get groups for user `root': No such file or
directory


Expected results:
# ./id root
uid=0(root) gid=0(root)
groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel)
context=root:unconfined_r:unconfined_t:SystemLow-SystemHigh


Additional info: This isn't a big deal for upstream coreutils, because soon it
will no longer use getgrent.

Comment 1 Jakub Jelinek 2008-04-10 10:07:35 UTC

This ought to be fixed in glibc-2.7.90-14, if not, please reopen.
