This is not how instances work in 389-ds. Each instance is fully
independent of another one, including database content and structure.
You cannot have instance that shares the same content with another one
unless you enable database chaining (and then there are some
limitations).

We used to have CA instance separate from the main IPA instance, for
example, but then merged them together in the same instance using two
different backends.

Standard IPA 389-ds instance already allows its access on the unix domain
socket with EXTERNAL/GSSAPI authentication. It is visible only within
the scope of the IPA master host, of course.

I'm still not sure what exactly you would like to achieve. All ports
that 389-ds listens to do support the same authentication methods except
LDAPI protocol (unix domain sockets) which supports automapping between
POSIX ID and a user object that it maps to.
