I'm working on the new CMS implementation project. We have ~4000 users in ExpressionEngine v 1.6.3 CMS.
The project requirement is, to let current EE members login to new CMS based on their encrypted credentials in EE.
Is the any way I can run an external php script utilizing Authentication Function from EE core $this->EE->auth->authenticate_username($username, $password)?
Any help will be appreciated.
