Package: coreutils
Version: 5.97-5.7
Severity: normal
Tags: patch
When you run id <username> it calls a built in function called getugroup which
in turn uses getgrent.
The getgrent function is not supported by nss hesiod which of course means id
doesn't return the supplementary
groups the user belongs to.
Instead getgrouplist should be used, this is a known issue, but since the
getgrouplist function didn't work well
with glibc 2.3.2 the change was reverted. Submitted is a patch for getugroup to
use getgrouplist if present.
This might also solve the > 32 groups bug though I haven't tested it.
