You need to create a change-set containing basic authentication parameters.
This change-set could then point to the change-set hosted in guvnor (or any
of its resources). Here is an example of a change-set using basic
authentication pointing to a package resource:
<change-set>
<add>
<resource source='
http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST
'
type='PKG' *basicAuthentication="enabled" username="admin" password="admin"
*
/>
</add>
</change-set>
Best,

> Hi all,
>>
>> I am using Drools Guvnor as follows:
>>
>> 1º Security configuration:
>>
>> <security:identity
>> authenticate-method="#{defaultAuthenticator.authenticate}"/>
>> <security:role-based-permission-resolver
>> enable-role-based-authorization="true"/>
>>
>> 2º User permission: an user as administrator with permissions of:
>> - Analyst for 'category=examples'
>> - package.developer for 'package=org.examples'
>>
>> What additional configuration is needed to consume a rules from an
>> application using a 'Knowledge Agent'?
>>
>> Someone has an example or tutorial to use of 'Knowledge Agent'?
>>
>> I hope someone can help me in this issue that is critical to use drools in
>> a real project. I attached the related files.

>> Thanks and regards,
