It only tells you that Services API is not supported for type 4 driver. It
is partly supported in type 2 driver, but full support of Services API you
will get only in JayBird 2.

We are almost done with it, there are few "cosmetic" things, so you can
already try version from HEAD. But beware, JayBird 2 is not compatible on
the interface level with JayBird 1.5 (except the org.firebirdsql.jdbc.*
package).

See the source code in HEAD - there is already FBUserManager that performs
all you need. You can try to port this code to JayBird 1.5, there should be
no big issues there.
