For others who want to use that instead of having a Username / Password
1) Copy the appropriate sqljdbc_auth.dll (either the X86 or the X64) to your path. (no, it does not work putting into the Aware/Tomcat/Lib folder. So I just copied it to the Windows folder). This file is located in:
<installation directory>\sqljdbc_<version><language>\auth\
2) Remove UserName and Password from the JDBC string and replace it with: IntegratedSecurity\=true;
3) Stare Aware and smile
(of course, this only works under Windows.)
