Connect Codeigniter to ODBC that uses Windows Authentication - codeigniter

Question

I am looking for a solution that will allow me to connect to MS SQL through an ODBC that uses Windows Authentication. I have tested and verified all of the rest of the code by using a standard ODBC connection that requires a user/pass. Below are the settings that work with that ODBC and the settings I have tried on the Windows Authentication ODBC.
Working database.php settings -standard user/pass connection
$active_group = 'jf2';
$active_record = TRUE;
$db['jf']['hostname'] = 'system DSN name';
$db['jf']['username'] = 'db_user';
$db['jf']['password'] = 'db_pass';
$db['jf']['database'] = 'db_name';
$db['jf']['dbdriver'] = 'odbc';
$db['jf']['dbprefix'] = '';
$db['jf']['pconnect'] = TRUE;
$db['jf']['db_debug'] = TRUE;
$db['jf']['cache_on'] = FALSE;
$db['jf']['cachedir'] = '';
$db['jf']['char_set'] = 'utf8';
$db['jf']['dbcollat'] = 'utf8_general_ci';
$db['jf']['swap_pre'] = '';
$db['jf']['autoinit'] = TRUE;
$db['jf']['stricton'] = FALSE;
non-working database.php settings - Windows Auth attempt
$active_group = 'jf1';
$active_record = TRUE;
$db['jf1']['hostname'] = 'system DSN name';
$db['jf1']['username'] = '';
$db['jf1']['password'] = '';
$db['jf1']['database'] = 'db_name';
$db['jf1']['dbdriver'] = 'odbc';
$db['jf1']['dbprefix'] = '';
$db['jf1']['pconnect'] = TRUE;
$db['jf1']['db_debug'] = TRUE;
$db['jf1']['cache_on'] = FALSE;
$db['jf1']['cachedir'] = '';
$db['jf1']['char_set'] = 'utf8';
$db['jf1']['dbcollat'] = 'utf8_general_ci';
$db['jf1']['swap_pre'] = '';
$db['jf1']['autoinit'] = TRUE;
$db['jf1']['stricton'] = FALSE;
Specifically, I am unsure what will go into the user/pass fields. The error is below:
A Database Error Occurred
Unable to connect to your database server using the provided settings.

Thanks for your help.

$db['jf1']['hostname'] = 'system DSN name';
$db['jf']['username'] = '';
$db['jf']['password'] = '';
$db['jf1']['database'] = 'db_name';
You are setting the username and password key on the jf database group instead of on the jf1 group.
$db['jf1']['hostname'] = 'system DSN name';
$db['jf1']['username'] = 'insert_username';
$db['jf1']['password'] = 'insert_password';
$db['jf1']['database'] = 'db_name';
