Component org.nuxeo.usermapper.service.UserMapperComponent

Documentation

This component expose a service to help mapping NuxeoPrincipal to userObject provided by an external system.

The mapping itself is configurable using an extension point.

Typical use cases include :

  • SSO plugin that are able to do Just In Time provisioning
    • SAML
    • Shibboleth
    • OpenId
    • Keyloack
  • User provisioning API (such as SCIM)

Requirements

Resolution Order

940
The resolution order represents the order in which this component has been resolved by the Nuxeo Runtime framework.
You can influence this order by adding "require" tags in your component declaration, to make sure it is resolved after another component.

Start Order

979
The start order represents the order in which this component has been started by the Nuxeo Runtime framework.
This number is interesting to tweak if your Java component interacts with other components, and needs to be started before or after another one.
It can be changed by implementing the method "Component#getApplicationStartedOrder()" on your Java component: components are sorted according to this reference value, in increasing order.
The default value is 1000, and the repository initialization uses number 100. Negative values can also be used.

    This component expose a service to help mapping NuxeoPrincipal to
    userObject provided by an external system.

    The mapping itself is configurable using an extension point.

    Typical use cases include :

    <ul>
      <li> SSO plugin that are able to do Just In Time provisioning </li>
      <ul>
        <li> SAML </li>
        <li> Shibboleth </li>

  <extension-point name="mapper">
    <documentation>
      Allow to contribute mapper classes that will be responsible for
      handling the mapping in 2 directions :

      <ul>
        <li> find and update NuxeoPrincipal given a userObject coming from
          the external system</li>
        <li> create an external userObject from a NuxeoPrincipal</li>
      </ul>

      Here is an example to contribute a custom class :
      <code>

        <mapper name="javaDummy"
          class="org.nuxeo.usermapper.test.dummy.DummyUserMapper">
          <parameters>
            <param name="param1">value1</param>
          </parameters>
        </mapper>

      </code>

      The contributed class has to implement the UserMapper interface.

      You can also contribute the implementation via a Groovy or JavaScript.

      In this case, simply omit the class attribute and add a script tag:
