Answer 1

The JDBC driver supports the use of Type 2 integrated authentication on Windows operating systems through the integratedSecurity connection string property. To use integrated authentication, copy the sqljdbc_auth.dll file to a directory on the Windows system path on the computer where the JDBC driver is installed. The sqljdbc_auth.dll files are installed in the following location:

\sqljdbc_\\auth\

For any operating system supported by the Microsoft JDBC Driver for SQL Server, see Using Kerberos Integrated Authentication to Connect to SQL Server for a description of a feature added in Microsoft JDBC Driver 4.0 for SQL Server that allows an application to connect to a database using integrated authentication with Type 4 Kerberos.

Note: If you are running a 32-bit Java Virtual Machine (JVM), use the sqljdbc_auth.dll file in the x86 folder, even if the operating system is the x64 version. If you are running a 64-bit JVM on a x64 processor, use the sqljdbc_auth.dll file in the x64 folder. Alternatively you can set the java.libary.path system property to specify the directory of the sqljdbc_auth.dll.

For example, if the JDBC driver is installed in the default directory, you can specify the location of the DLL by using the following virtual machine (VM) argument when the Java application is started: -Djava.library.path=C:\Microsoft JDBC Driver 4.0 for SQL

Server\sqljdbc_\enu\auth\x86
