What is pamtester?

pamtester is a tiny utility program to test the pluggable authentication modules (PAM) facility, which is a de facto standard of unified authentication management mechanism in many unices and similar OSes including Solaris, HP-UX, *BSD, MacOSX and Linux.

While specifically designed to help PAM module authors to test their modules, that might also be handy for system administrators interested in building a centralised authentication system using common standards such as NIS, SASL and LDAP.
