How to customize the login function

Hello,

We are currently implementing user authentication (ID and password) through an external web page that was developed separately from the standard Aras interface.

After successful authentication, we would like to redirect users to the Aras main page by logging in via a URL that includes the user ID, password, and database name.

If anyone is familiar with how to implement this kind of customization, we would greatly appreciate your advice.
For reference, our Aras Innovator version is Release 35.

Thank you in advance!
