This is a standard ASP.NET profile configuration section. All profile properties of the corresponding user get turned into claims when requesting a token from StarterSTS.
You can either manually edit this file, or use the IIS7 manager to create and modify the properties.
The corresponding configuration file looks like this:
<profile
automaticSaveEnabled="false"
defaultProvider="Profile">
<providers>
<add
name="Profile"
connectionStringName="ProviderDB"
applicationName="/"
type="System.Web.Profile.SqlProfileProvider, System.Web,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</providers>
<!-- properties that should get turned into claims go here
-->
<properties>
<add
allowAnonymous="false"
defaultValue=""
name="WebPage"
readOnly="false"
serializeAs="String"
type="System.String" />
<add
allowAnonymous="false"
defaultValue=""
name="TwitterName"
readOnly="false"
serializeAs="String"
type="System.String" />
</properties>
</profile>
