pam_echo - Echo PAM module
[service-name] module-type control-flag pam_echo [arguments]
The echo service module for PAM displays its arguments to the user, separated by spaces, using the current conversation function.
If the % character occurs anywhere in the arguments to pam_echo, it is assumed to introduce one of the following escape sequences:
| %H || The name of the host on which the client runs (PAM_RHOST). |
| %s || The current service name (PAM_SERVICE). |
| %t || The name of the controlling tty (PAM_TTY). |
| %U || The applicants user name (PAM_RUSER). |
| %u || The target accounts user name (PAM_USER). |
Any other two-character sequence beginning with % expands to the character following the % character.
