How to use multiple Login Modules to authenticate SOAP webservice calls from different Consumers ?

Issue

• Currently SOAP webservice calls in JBoss EAP 6.4 are authenticated with SAML 2 tokens.
  A new webservice Consumer (SAP) is not able to generate SAML 2 tokens. In the future we would like provide the Username / Password authentication for this Consumer .

• How to configure JBoss to support two different login modules?

• We think that we have to create two different SOAP webservice modules with differnt url's.

Webservice module to authenticate with samltoken-authentication

jboss-web.xml:  <security-domain>samltoken-authentication</security-domain>
web.xml: <url-pattern>/services/v1/*</url-pattern>

Webservice module to authenticate with username-password-authentication
jboss-web.xml:  <security-domain>username-password-authentication</security-domain>
web.xml: <url-pattern>/services/otherUri/v1/*</url-pattern>

• In the standalone.xml file,

<!-- Login module for samltoken-authentication -->
<security-domain name="samltoken-authentication" cache-type="default">
                    <authentication>
...
<!-- Login modul for username / password authentication -->
<security-domain name="username-password-authentication" cache-type="default">
                    <authentication>
....

• Is this the correct solution? Or do you know a better one?
