How to access configuration of custom role decoder

[pmm]

We are evaluating a possible deployment scenario where we would store the groups of a user in LDAP but the roles associated with a group in a database. It is our understanding that we need to implement a custom role decoder (implement org.wildfly.security.authz.RoleDecoder) for this. If we have a configuration like this:

<custom-role-decoder name="acme-custom" module="acme-elytron" class-name="com.acme.CustomRoleDecoder">

  <configuration>

    <property name="key1" value="value1"/>

  </configuration>

</custom-role-decoder>

How do we access the configuration from inside the RoleDecoder implementation?

Currently your custom component should implement the interface 'org.wildfly.extension.elytron.Configurable'.

public interface Configurable {

    void initialize(final Map<String, String> configuration);

}

This is part of the WildFly Elytron subsystem so can be found in org.wildfly.core:wildfly-elytron-integration

The initialize method will be called and the configured properties passed in.

We are currently making a change where the interface will be optional so instead we will just detect if the custom component contains an initialize method that takes a Map as an argument and will automatically use that.

Is there somewhere some documentation that I can read up on? I found quite some information on using the built in configuration but not a whole lot on extending.

My colleague has just put together this blog post for custom security realms, the information about configuration of a custom component is applicable to all of the custom component types.
