SQLServer IntegratedSecurity related

Hi all, I have a problem trying to create a data service under WSAS 3.1.3 running on my desktop (Windows Vista). I would like to connect to the MSSQLserver using the windows native authentication. Here is the jdbc string: jdbc:sqlserver://teraclope\chiefmaster:1592;databaseName=EhlStages;Provider=SQLOLEDB.1; I placed the sqljdbc4 jar in WSAS_ROOT\repository\components as well as in WSAS_ROOT\repository\lib directories. I also placed sqljdbc_auth.dll in (JAVA_HOME\bin). As the username, password is assumed to be supplied automatically by the sqljdbc_auth.dll these params can only be empty. My dbs config file looks like this:     <config id="ehlstages">         <property name="org.wso2.ws.dataservice.driver">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>         <property name="org.wso2.ws.dataservice.protocol">jdbc:sqlserver://teraclope\chiefmaster:1592;databaseName=EhlStages;Provider=SQLOLEDB.1;IntegratedSecurity=true;</property>         <property name="org.wso2.ws.dataservice.user"/>         <property name="org.wso2.ws.dataservice.password"/>         <property name="org.wso2.ws.dataservice.minpoolsize">1</property>         <property name="org.wso2.ws.dataservice.maxpoolsize">1</property>         <property name="org.wso2.ws.dataservice.autocommit">true</property>     </config> FYI, the above jdbc connect string has been in production in one of our java based ESB environment. My questions:   1. Has the MSSQLserver been tested with IntegratedSecurity option ?   2. Keeping the org.wso2.ws.dataservice.user, org.wso2.ws.dataservice.password empty results in appending empty strings ? Any suggestions for progressing forward will be much appreciated!
