It uses getpwnam() and getspnam() routines for authentication.
This has the following advantages over the NCSA module:
When used for authenticating to local UNIX shadow password databases the program must be running as root or else it won't have sufficient permissions to access the user password database. Such use of this program is not recommended, but if you absolutely need to then make the program setuid root
Please note that in such configurations it is also strongly recommended that the program is moved into a directory where normal users cannot access it, as this mode of operation will allow any local user to brute-force other users passwords. Also note the program has not been fully audited and the author cannot be held responsible for any security issues due to such installations.
