This is a place where the LTP fails regularily. The correct solution is to read the value from /proc/sys/kernel/ngroups_max. I'd be happy to talk about it on #ltp on freenode - I fixed this for pid_max in ltp in a few places over the end of last week and the weekend. The kernel headers do not necessarily match the running kernel. Please don't count on it.
