I would go the second way.

You mentioned to have a "global" database. This suggests there is also
something "local". While is is possible to let distributed applications
access a "global" database, this usually is a great security risk
(you database communication endpoints are open to anybody - among
others hackers that may try to steal or corrupt your data).
Therefore, you usually use a client server architecture where the
database is hidden behind a server interface. The clients do not
directly connect to the database but to the server interface which in
turn access the database. Part of the server interface is
authentication (who wants my services) and authorization (which access
should I provide to the authenticated user).
Someone else already suggested to implement a web application for your
project. Web application frameworks (such as e.g. "Django") come with
components to easily (and rather safely) implement the common tasks
of authentication and authorization.
