Datasource *-ds.xml security with Active Directory

Our security requiresments indicate that our database accouts must be controlled in Active Directory.  So the user id and password that I would normally store in a JBoss *-ds.xml file has to come from Active Directory. While I see a ton of How-To's on encrypting and securing the password in this file, I am finding nothing on how I can have JBoss Datasource files use AD user id's and passwords while only specifically knowing the user id and not storing the password in the JBoss Datasource file.  Help please?  Oh and we're useing JBoss EAP 6.0.1 with EnterpriseDB

Thanks,
