Sounds kind of like a bug in glibc that was fixed in 2.3.4-2.13.  You're 
probably best off reporting this to RH via bugzilla.  I might be able to 
help you track down the precise cause of the problem, if you'd like, and 
help Red Hat get the issue resolved more quickly.

* confirm the version of glibc on that system
* install "ltrace" if necessary
* stop the "nscd" service temporarily
* run "ltrace -s 512 -S getent group massweb > /tmp/ltrace.getent 2>&1"

Email me /tmp/ltrace.getent off-list.  If there is any private info in 
/etc/ldap.conf, you'll want to clear it out of the ltrace file before 
sending it.
