+++ This bug was initially created as a clone of Bug #703880 +++
Description of problem:
On a machine using NIS for passwd in compat mode and with a big
netgroup (~ 790 users), the uid resolution is unreliable.
Version-Release number of selected component (if applicable):
How reproducible: every time, with and without nscd running.
Steps to Reproduce:
1. in /etc/nsswitch.conf: passwd: compat
2. in /etc/passwd: +@NETGROUP::::::
where NETGROUP contains ~ 790 users.
3. "ls -l" in a directory containing a sub-directory per user owned by
each of them.
All the uid's are not reliably translated to user names.
All the uid's translated to user names.
A fix that works (at least for me) is to recompile glibc with the
following flags for ypclnt.c in glibc-fedora.patch
+CFLAGS-ypclnt.c = -fno-strict-aliasing -DUSE_BINDINGDIR=1
+CFLAGS-ypclnt.c = -fno-strict-aliasing
