Double check when errnop is set and make sure it sticks to the values as defined here: http://www.gnu.org/software/libc/manual/html_node/NSS-Modules-Interface.html#NSS-Modules-Interface

Secondly, ensure other calls set errnop when they error.

With forking and using pipes, you can also set the effective UID/GID for the script before the script starts.

Hello,
What is a purpose of invertion of result_status in _nss_exec_getpwent_r_locked ?

NSS_STATUS_SUCCESS is 1.
From the _nss_exec_getpwent_r_locked return will be NSS_STATUS_SUCCESS even if it get error from nss_exec_script_long.
That may cause infinite loop when getpwent is used to enumerate users because getpwent will always return pointer instead of 0.

It would be nice to mimic the library as found here: https://support.software.dell.com/authentication-services/kb/14197
