getpwent() isn't guaranteed to be implemented, or implemented in the
same way, for all NSS types.
Most programs should use getpwnam() (preferably) or getpwuid() instead.
For example, getpwent() is not implemented for nss_nds, and only
returns users in the root container for nss_ldap. Also be aware
that getpwuid() returns NULL for nss_ldap under certain circumstances.
