How to allow user to change passowrd in Access Project (.ADP)?

I need to allow my users to change their passwords on my Access Project.

In normal database files (.MDB) I would normally use something like:
RunCommand acCmdSetDatabasePassword
behind a command button or on a Menu, and it always worked... But now I need
the same functionality but in an Access Project (.ADP).

This functionality is offered trough the built-in menu [TOOLS>SECURITY>Set
User Password...], but I'm not allowing this type of menus in my Project and
programatically I'm not able to have the acCmdSetDatabasePassword to work
(probably its only valid for MDB projects): It raises error 2046 stating that
"the command is not available at that time".

Does any one knows how to programatically allow a user to change its
password in AN ACCESS DATABASE PROJECT (.ADP)?

Thanks,
Luis
