2.3. Creating PAM Modules
New PAM modules can be created or added at any time for use by PAM-aware applications. PAM-aware programs can immediately use the new module and any methods it defines without being recompiled or otherwise modified. This allows developers and system administrators to mix-and-match, as well as test, authentication methods for different programs without recompiling them.
Documentation on writing modules is included in the
/usr/share/doc/pam-
version# directory.
