pam_exec
PAM_EXEC(8) Linux-PAM Manual PAM_EXEC(8)NAME
pam_exec - PAM module which calls an external command
SYNOPSIS
pam_exec.so [debug] [expose_authtok] [seteuid] [quiet] [log=file] command [...]
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.
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, account, password and session) are provided.
RETURN VALUES
PAM_SUCCESS
The external command was run successfully.
PAM_SERVICE_ERR
No argument or a wrong number of arguments were given.
PAM_SYSTEM_ERR
A system error occurred or the command to execute failed.
PAM_IGNORE
pam_setcred was called, which does not execute the command.
EXAMPLES
Add the following line to /etc/pam.d/passwd to rebuild the NIS database after each local password change:
password optional pam_exec.so seteuid /usr/bin/make -C /var/yp
This will execute the command
make -C /var/yp
with effective user ID.
