Connecting to postgresql using SSPI via JDBC

Hi everyone,

I've got a postgresql configured with sspi authentication.
The authentication works usng psql, however, when attempting to connect via
the jdbc driver I get this exception:

"org.postgresql.util.PSQLException: The authentication type 9 is not
supported. Check that you have configured the pg_hba.conf file to include
the client's IP address or subnet, and that it is using an authentication
scheme supported by the driver."

Does the jdbc driver simply not support sspi?
Does it support ldap?

Thanks,
Idan
