pgadmin4 usage as of web proxy for developers

Good afternoon,

As the new pgadmin (pgadmin4) rely on web browser for the display, I
wanted to use it like a 'phpMyAdmin', .. for postgresql, in a replacement
of phppgadmin.

But its user management make it hard (maybe I'm wrong about that) to plug
it to a corporate ldap authentication and preconfigure server that users
will use with their own credentials.

Despite I know how to plug our active directory servers to PAM, there are 2
points to handle :
- how to make pam the way to authenticate users
- how to let users use their own credentials for pre configured servers -
I'd like them to use their own user instead of configuring servers with
mutualized users.

Is there something planned to make this possible ?
or is it already possible to work this way ?

I found no info over internet about this.

Thank you very much for some help :)

here are the step I used for my 'server side' installation of pgadmin 4,
for information.
