Hi Jeff,

The most common such system is LDAP (or LDAPS if it is more remote
than in the same room). You can also use RADIUS, NIS(+) etc. I believe
that Debian (Pluggable Authentication Modules, actually) can also
authenticate against a PostgreSQL, MySQL or other database.

Then there are all the OAuth mechanisms that allow you to authenticate
against common services such as (dare I say it) Google, Facebook etc.

What is the actual use case here? What do you want the "someone" to
authenticate for? Shell access? Web access? IOT/MQTT access? etc.

cheers,
Bob Edwards.
