Upgrading Stash (2.12) to BitBucket Server. Fatal Error: This driver is not configured for integrated authentication.

[JonSeidmann]

I am attempting to upgrade an instance of Stash 2.12 to the latest version of Bitbucket (4.6). Once I upgrade the latest version of Bitbucket, I get:

A fatal error has occurred

The following problem occurred, which prevents Atlassian Bitbucket from starting:

• The database, as currently configured, is not accessible. 
  This driver is not configured for integrated authentication. ClientConnectionId:653d7fa9-85b6-40c2-8ea8-be74f8acbeee

I tried installing Java jdk1.8 which did not help. I do get references in the log file to "no sqljdbc_auth in java.library.path". Any help regarding how I can get this up and running?

Edit: Should mention that I am using SQL Server Express 2012

Based on the JVM being used to run Bitbucket Server, rename either the x64 or x86 DLL to sqljdbc_auth.dll in lib/native. I just renamed the x64 file to sqljdbc_auth.dll and everything worked fine (needed to reboot Bitbucket, of course).

Based on the stackoverflow answer for a similar problem, sounds like you have to copy a *.dll file into your JRE's "java.library.path" which is typically equivalent to the $PATH environment variable on windows.  And the *.dll file has to be compiled to the same architecture that your JRE is using (e.g., 64bit vs. 32bit):
