The plug-in of OpenLDAP directory server pqChecker,allows to control the passwords content robustness. It allows, also, to read / change the parameters of its operation, as well as the possibility of broadcasting new passwords through a Java compliant API.

The pqMessenger application is a middleware that use the programming interface of pqChecker and ensures a communication with a JMS compliant server. To do that, the application manages two JMS topic:

  • Topic for reading and modifying parameters.
  • Topic for broadcasting modified passwords.
To ensure the security of the exchanged data, especially the password, this communication is performed within a TLS encrypted tunnel.

Operating environment
OpenLDAP password policy pwdCheckQuality

pqMessenger allows the settings application to read and change password quality parameters. This setup application must act as a JMS server. This operating mechanism makes it possible to manage these parameters without any particular system constraint (need for intervention of a system administrator).

It also allows, if this feature is enabled in pqChecker, to broadcast the new values of the passwords as soon as they are modified.


pqMessenger is a free and opensource software. It is licensed under the GNU GPL v3+ license.
