pam_exec — PAM module which calls an external 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, and PAM_USER
.
OPTIONS
debug
Print debug information.
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.
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.
