NSS and PAM, the subsystem being used by getpwid_r() do not work with
non-dynamicly linked programs.  This is because NSS and PAM loads
shared libraries to do the job.

In short, you can not access the user database or check password from
staticly linked programs.

Be aware that this list is no longer used by the glibc maintainers.
It is so filled with spam that it because almost impossible to read.
Check out <URL:http://sources.redhat.com/glibc/> for info on other
places to contact the glibc maintainers.  I'm not one of the people
with write access to glibc source. :)
