After fresh installation of Wildfly we got pre-defined security domains such as "jaspitest", "jboss-web-policy" or "other" etc. I can see them also in standalone.xml

<security-domain name="other" cache-type="default">
	<authentication>
		<login-module code="Remoting" flag="optional">
			<module-option name="password-stacking" value="useFirstPass"/>
		</login-module>
		<login-module code="RealmDirect" flag="required">
			<module-option name="password-stacking" value="useFirstPass"/>
		</login-module>
	</authentication>
</security-domain>

As you can see, the security domain with name "other" has two login modules defined in authentication, each of them has one module-option defined in it.

But we can not see any definition of module options in web console! (See screenshot in attatchment)

Also in user defined security domains we can not save module options correctly over web console.
