Authentication of users with login accounts on Linux / MacOS operating systems using the build-in PAM provider.

This login type is a sub-type of the System Authentication. Setting up an application specific PAM login configuration in /etc/pam.d/<corePluginId> is supported. The <corePluginID> can be obtained from the log file line "Starting initialization of application with ID". The authentication provider uses /etc/pam.d/login as fallback.
