I am trying to connect to a SQL server 2008 database from within Eclipse. My SQL server uses integrated authentication for login. Eclipse prompts for integrated authentication , but it is unable to login. I get an error message as "This driver is not configured for Integrated authentication". The sqljdbc_auth.dll of the JDBC driver is needed. I put it in the system path, but it does not work. I do not know how to make Eclipse use this file. Can somebody help?
