I configured the ldap idm for the user and role configuration. I can set the provider url and administrator credentials as options in the picketlink-idm-ldap-config.xml:

But how can I set this options programmatically in the portal extension and read this properties from an own configuration file?

<options>

          <option>

            <name>providerURL</name>

            <value>ldap://localhost:1389</value>

          </option>

          <option>

            <name>adminDN</name>

            <value>cn=Directory Manager</value>

          </option>

          <option>

            <name>adminPassword</name>

            <value>password</value>

          </option>

        </options>
