The pam_echo PAM module is for printing text messages to inform user
about special things. Sequences starting with the % character are
interpreted in the following way:
The name of the remote host (PAM_RHOST).
The name of the local host.
The service name (PAM_SERVICE).
The name of the controlling terminal (PAM_TTY).
The remote user name (PAM_RUSER).
The local user name (PAM_USER).
All other sequences beginning with % expands to the characters
following the % character.
For an example of the use of this module, we show how it may be used
to print information about good passwords:
password optional pam_echo.so file=/usr/share/doc/good-password.txt
password required pam_unix.so
