Описание (Description)
pam_exec is a PAM module that can be used to run an external
command.
The child's environment is set to the current PAM environment
list, as returned by pam_getenvlist(3) In addition, the following
PAM items are exported as environment variables: PAM_RHOST,
PAM_RUSER, PAM_SERVICE, PAM_TTY, PAM_USER and PAM_TYPE, which
contains one of the module types: account, auth, password,
open_session and close_session.
Commands called by pam_exec need to be aware of that the user can
have controll over the environment.
Параметры (Options)
debug
Print debug information.
expose_authtok
During authentication the calling command can read the
password from stdin(3). Only first PAM_MAX_RESP_SIZE bytes of
a password are provided to the command.
log=file
The output of the command is appended to file
type=type
Only run the command if the module type matches the given
type.
stdout
Per default the output of the executed command is written to
/dev/null. With this option, the stdout output of the
executed command is redirected to the calling application.
It's in the responsibility of this application what happens
with the output. The log option is ignored.
quiet
Per default pam_exec.so will echo the exit status of the
external command if it fails. Specifying this option will
suppress the message.
seteuid
Per default pam_exec.so will execute the external command
with the real user ID of the calling process. Specifying this
option means the command is run with the effective user ID.
