Hard to say without looking at the specific code, trying to implement this.

But I would assume, those fields aren't available because the custom
federation
LDAP provider doesn't implement the underlying interface methods, that
are actually responsible for performing the action, when particular button
is clicked?

What happens, if you override the specific methods from the default LDAP
provider, responsible for accessing these fields, and point them back
to the default implementation (e.g. by calling super() with the same args /
params within the overridden interface method)?

Is the issue, that you can't see the fields, newly introduced by your
custom LDAP
federation provider, or that some fields from the default screen aren't
accessible /
usable upon the implementation of that a provider? Or both?
