The NIS "Client Services" configuration page does not
list the winbind NIS maps of winbind and wins (provided
by the /usr/lib/libnss_winbind.so and
/usr/lib/libnss_wins.so respectively)
Is it possibly to make this list semi-dynamic by
pulling in the list of /usr/lib/libnss_*.so? (and
/usr/lib64/libnss_*.so on x86_64 systems)
