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.
OPTIONS
debug
-
Print debug information.
expose_authtok
-
During authentication the calling command can read the password from
stdin(3).
log=file
-
The output of the command is appended to
file
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.
MODULE TYPES PROVIDED
All module types (auth,

and
session) are provided.
RETURN VALUES
PAM_SUCCESS
-
The external command was run successfully.
PAM_SERVICE_ERR

EXAMPLES
Add the following line to
/etc/pam.d/passwd
to rebuild the NIS database after each local password change:
-
passwd optional pam_exec.so seteuid make -C /var/yp
This will execute the command
-
make -C /var/yp
with effective user ID.
