===== SP element

Here is the explanation of the SP element attributes: 

[source,xml]
----

<SP entityID="sp"
    sslPolicy="ssl"
    nameIDPolicyFormat="format"
    forceAuthentication="true"
    isPassive="false"
    keepDOMAssertion="true"
    autodetectBearerOnly="false">
...
</SP>
----
entityID::
  This is the identifier for this client.
  The IdP needs this value to determine who the client is that is communicating with it. This setting is _REQUIRED_.

sslPolicy::
  This is the SSL policy the adapter will enforce.
  Valid values are: `ALL`, `EXTERNAL`, and `NONE`.
  For `ALL`, all requests must come in via HTTPS.
  For `EXTERNAL`, only non-private IP addresses must come over the wire via HTTPS.
  For `NONE`, no requests are required to come over via HTTPS.
  This setting is _OPTIONAL_. Default value is `EXTERNAL`.

nameIDPolicyFormat::
  SAML clients can request a specific NameID Subject format.
  Fill in this value if you want a specific format.
  It must be a standard SAML format identifier: `urn:oasis:names:tc:SAML:2.0:nameid-format:transient`.
  This setting is _OPTIONAL_.
  By default, no special format is requested. 

forceAuthentication::
  SAML clients can request that a user is re-authenticated even if they are already logged in at the IdP.
  Set this to `true` to enable. This setting is _OPTIONAL_.
  Default value is `false`.

isPassive::
  SAML clients can request that a user is never asked to authenticate even if they are not logged in at the IdP.
  Set this to `true` if you want this.
  Do not use together with `forceAuthentication` as they are opposite. This setting is _OPTIONAL_.
  Default value is `false`.

turnOffChangeSessionIdOnLogin::
  The session ID is changed by default on a successful login on some platforms to plug a security attack vector.
  Change this to `true` to disable this.  It is recommended you do not turn it off.
  Default value is `false`.

autodetectBearerOnly::
  This should be set to __true__ if your application serves both a web application and web services (for example SOAP or REST).
  It allows you to redirect unauthenticated users of the web application to the {project_name} login page,
  but send an HTTP `401` status code to unauthenticated SOAP or REST clients instead as they would not understand a redirect to the login page.
  {project_name} auto-detects SOAP or REST clients based on typical headers like `X-Requested-With`, `SOAPAction` or `Accept`.
  The default value is _false_.

logoutPage::
  This sets the page to display after logout. If the page is a full URL, such as `http://web.example.com/logout.html`,
  the user is redirected after logout to that page using the HTTP `302` status code. If a link without scheme part is specified,
  such as `/logout.jsp`, the page is displayed after logout, _regardless of whether it lies in a protected area according
  to `security-constraint` declarations in web.xml_, and the page is resolved relative to the deployment context root.

keepDOMAssertion::
  This attribute should be set to __true__ to make the adapter store the DOM representation of the assertion in its
  original form inside the `SamlPrincipal` associated to the request. The assertion document can be retrieved using
  the method `getAssertionDocument` inside the principal. This is specially useful when re-playing a signed assertion.
  The returned document is the one that was generated parsing the SAML response received by the {project_name} server.
  This setting is _OPTIONAL_ and its default value is __false__ (the document is not saved inside the principal).
