title: node-mssql - User authentication fails when specifying database
body: <p>I'm trying to connect to SQL server using the node-mssql package. </p>
  
  <p>I can successfully connect to the default database with the following configuration:</p>
  
  <pre><code>{
     "user": "service_user",
     "password": "myPass",
     "server": "10.2.xxx.xxx",
  }
  </code></pre>
  
  <p>However, there are multiple databases I would like to connect to. When I try configuring my connection to target a specific database, like so, it fails:</p>
  
  <pre><code>{
     "user": "service_user",
     "password": "myPass",
     "server": "10.2.xxx.xxx",
     "database": "Q-xxx-SQL-xxx\\DB2"
  }
  </code></pre>
  
  <p>I have also tried to this configuration that also fails:</p>
  
  <pre><code>{
     "user": "service_user",
     "password": "myPass",
     "server": "10.2.xxx.xxx\\Q-xxx-SQL-xxx",
     "database": "DB2"
  }
  </code></pre>
  
  <p>When I try to connect to a specific DB, I get the following error: </p>
  
  <pre><code>{ ConnectionError: Login failed for user 'service_user'.

  <p>When I log in to the server that is running the DBs, I can successfully read and write into the target DB in SSMS.</p>
