Pluggable Authentication Module (PAM) on UNIX and Linux

You can use PAM with the IBM Informix ODBC Driver on the UNIX and Linux operating systems that support PAM. PAM enables system administrators to implement different authentication mechanisms for different applications. For example, the needs of a system like the UNIX login program might be different from an application that accesses sensitive information from a database. PAM allows for many such scenarios in a single machine, because the authentication services are attached at the application level.
