The unique id associated with this portlet is 48. The IFramePortlet class extends javax.portlet.GenericPortlet.
The source [http://content.liferay.com/document/api/portal-ejb/com/liferay/portlet/IFramePortlet.java.html] of
this class shows that this class prints an IFRAME tag that references an external site. This portlet is editable
and viewable by HTML browsers. The preferences bind the name src with the default value of http://www.gfa.org.
The auth value, if set to true, will attempt to authenticate the user to the external IFrame application. The authtype value can be set to basic or form. Basic authentication appends the login information to the URL and form
authentication requires a post to the external IFrame application. The form-method value can be set to get or
post. This is only used if you are using form authentication. The user-name value sets the user name for authentication. If you are using basic authentication, then you just need to set the user name. If using form authentication, you need to set the user name as a key value pair like acme_login=test@acme.com. The password
value sets the password for authentication. If using basic authentication, you just need the password. If using
form authentication, set the password as a key value pair like acme_password=password. The hidden-variables value is used for form authentication. Some forms require certain prepopulated fields in order to proceed
with authentication. Separate each key and value with a = and each key value pair with a ;. Users must have
either the Power User or User role to access this portlet. The roles can be changed at run time via the Admin
portlet.
