I am trying to connect to oracle DB using Oracle SQL Developer (Version 3.0.04) Connection parameters follows,

host : port : user : xxxx password : sssss service name : asdf.somedomain.com

When connecting I am getting the following error

Unsupported verifier type.

I am able to ping the host so no network problem. I have another server in the same network which works perfectly fine.
