Yes, that looks like it should work- is it not?

Note that with an IPA setup, similar to if you were running Active
Directory, you have Kerberos and a KDC available, which is a much better
authentication mechanism that removes the need for the database sever to
reach out to another system to handle the authentication, and avoids
having the user's password sent to the database server.  You might want
to consider using that (which is called 'gssapi' in PostgreSQL, which is
basically generalized Kerberos) instead of LDAP.
