    pam_exec: Use program exit status as return code
    
    pam_exec(8) now accepts a new option "return_prog_exit_status". When
    set, the program exit status is used as the pam_exec return code. It
    allows the program to tell why the step failed (eg. user unknown).
    However, if it exits with a code not allowed by the calling PAM service
    module function (see $PAM_SM_FUNC below), a warning is logged and
    PAM_SERVICE_ERR is returned.
    
    Obtained-from:  FreeBSD
