Post Hook configuration

You can write a script that will be called it the password was changed. This allow for example to update a file or a database on password change.

This script must be executable by the user running Apache. It will take 3 arguments:

  • $login : the user login
  • $newpassword : the new password
  • $oldpassword : the old password
The old password is only provided on standard password change, not on password reset

To declare this script, use:

$posthook = "/usr/share/self-service-password/";

You can choose to display an error if the script return code is greater than 0:

$display_posthook_error = true;

The displayed message will be the first line of the script output.

Here is an example of a simple posthook script:

echo `date` >> /tmp/posthook.log
echo "$LOGIN / $NEWPASSWORD / $OLDPASSWORD" >> /tmp/posthook.log
... there is an error ...
echo "Posthook script has failed"
exit 1
... there is no error ...
exit 0
This script is an example, do use not it in production: passwords should never be put in logs. Write your own script to propagate the password in a safe place
If you are using systemd, it is possible that the PrivateTmp feature is enabled by default for Apache (in your httpd.service or apache2.service).

When enabled, all logs written from to /tmp will be redirected to /tmp/systemd-private-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-apache2.service-XXXXXX/tmp or similar.
