The JDBC driver supports gssapi, but not sspi.  It's possible that the 
existing gssapi support could be used to implement sspi, but no one has 
tried that.

Yes, no specific client support is needed for LDAP authentication, that is 
all done server side.  Using LDAP transmits the password from the driver 
to the server in plaintext form, so you should use a SSL connection if 
you're worried about security.
