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.
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.
The services auth, account, password and session are supported.
PAM_SUCCESS
The external command runs successfull.
PAM_SERVICE_ERR
No argument or a wrong number of arguments were given.
PAM_SYSTEM_ERR
A system error occured or the command to execute failed.
PAM_IGNORE
pam_setcred was called, which does not execute the command.
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.
