I'm trying to connect to a SQL Server database using a JDBC connection from Logstash installed on a Linux server. I'm running into issues with the security portion of it. This is my current connection string:

> jdbc\_connection\_string =\> "jdbc:sqlserver://servername:1433;databasename=dbname;integratedSecurity=true;authenticationScheme=JavaKerberos"  
> jdbc\_ucser =\> "user"  
> jdbc\_password =\> "pass"

When I try to run logstash using this, I get a SQLServer error: Integrated authentication failed. I've tried a couple different configurations using/not using integrated, using/not using authenticationScheme, and I can't get it to work at all. Any ideas for me?
