How does JBoss Data Services handle authentication when multiple security domains are defined?

Issue

• Authenticating to a VDB through JDBC with Multiple Security Domains in Teiid
• We have Multiple Security Domains defined for Teiid in teiid-jboss-beans.xml like this:

<property name="securityDomains">teiid-security,application1-security,application2-security</property>

• which Security Domain will be used when connecting through JDBC when multiple domains are configured
• Is it possible to specify the accurate Teiid Security Domain required for authorization and authentication when using JDBC connections
