Flex 1.5 syntax
In Flex 1.5, you specified the type of authentication and the role in the named service
definition in the flex-config.xml file:
<named>
<object name="myobj">
<use-custom-authentication>true</use-custom-authentication>
<roles>
<role>sampleusers</role>
</roles>
</object>
</named>
Flex 2 syntax
In Flex 2, you define the security constraint in the services-config.xml file:
<service-config>
<services>
... // Destinations are defined here.
</services>
<security>
<security-constraint id="sample-users">
<auth-method>Custom</auth-method>
<roles>
<role>sampleusers</role>
</roles>
</security-constraint>
</security>
</service-config>
You then refer to that security constraint in your destination definition, which is also in the
services-config.xml file or a file that it includes by reference:
<destination>
...
<security>
<security-constraint ref="sample-users"/>
</security>
</destination>
