Use a <connection-property>. From the schema:
The connection-property element allows you to pass in arbitrary connection properties to the Driver.connect(url, props) method. Each connection-property specifies a string name/value pair with the property name coming from the name attribute and the value coming from the element content. Ex: <connection-property name="char.encoding">UTF-8</connection-property>
Justin you are the man!!!
Added the following to the standalone.xml and I am able to connect to the database.
<connection-property name="securityMechanism"> 4 </connection-property>
