Confluence Server upgraded from 5.8.4 to 6.6.0, can't connect to SQL DB via JDB

Question

I am upgrading my Development instance of Confluence from v5.8.4 to v6.6.0 and using the com.microsoft.sqlserver.jdbc.SQLServerDriver driver, cannot connect to the existing database on MS SQL Server using a domain service account (mydomain\mylogin).

On v5.8.4, connection to SQL Server uses the net.sourceforge.jtds.jdbc.Driver and connects like this:

jdbc:jtds:sqlserver://myserver:1433/Confluence;domain=mydomain

I've iterated configurations many times using the com.microsoft.sqlserver.jdbc.SQLServerDriver, based on the instructions in https://confluence.atlassian.com/confkb/migrate-from-the-jtds-driver-to-the-supported-microsoft-sql-server-driver-in-confluence-6-4-or-later-939505122.html, with strings like this:

jdbc:sqlserver://myserver:1433;database=Confluence;

With the added property "IntegratedSecurity=true", the login is ignoring the configured username/password and passing "mydomain\myservername" to the DB (which is rejected).  What I need to do is pass "mydomain\mylogin".  I cannot find relevant examples online. Has anyone successfully configured this?

Thanks for the repost and followup Ann! :)

Jamie figured out that if he added the IntegratedSecurity=true property to the JDBC connection string, the MS JDBC driver would pass through to the database the credentials used to run the Windows service. So a big part of the trick was changing the default Local System as the account running the service, to the domain account he wanted to connect to the database with.

Using IntegratedSecurity=true causes the database driver to ignore the username and password in confluence.cfg.xml.

We did some testing but found we need more information to continue. So that we can have a closer look, I opened a support request on your behalf. You should get an email from the portal shortly.
