SQL connection as domain service account (8.1.2)

Hello All, 

The scenario:  I need to make the connection to the SQL server as one domain account, then log in to the tools via AD authentication as my own AD account. 

The setup so far:   I am trying to use the advanced connection from the normal DB connector screen. Note, if you use the config encryptor you go through the same screens. 


The issue:   When attempting to create this connection it seems as if the credentials are not being properly passed. I get an error telling me the login failed for a user with no username.

Does anyone have experience setting up this situation that could help?
