Note that the link you posted is to an old copy of the
documentation. For 4.1, docs would be here:

create-zone etc. rely on the Master/Slave featureset. These are not
supported by the LDAP backend.

Only gsql, really. Probably remote if you implement everything.
The bindbackend has some limitations that make some operations fail.

Yeah. For now the answer is easy: if you want to use the API, use
one of the gsql backends.
