LDAP authentication is well documented:
https://www.postgresql.org/docs/current/auth-ldap.html

But I don't think you are on the right track.

"pg_signal_backend" cannot login, it is a role to which you add a login user
to give it certain privileges.  So you don't need to authenticate the role.

"postgres" is the installation superuser.  If security is important for you,
you won't set a password for that user and you won't allow remote logins
with that user.

But for your application users LDAP authentication is a fine thing, and not
hard to set up if you know a little bit about LDAP.
