Associate Sitefinity CMS roles to external claims

When you use third party identity providers, such as ADFS, you can configure Sitefinity CMS to automatically maintain the membership of users in Sitefinity roles when the role of a user in ADFS changes or a new user is created.

EXAMPLE: A user is assigned a new role in ADFS. You can map this role to a role in Sitefinity CMS. Then, all users that acquire the role in ADFS will be automatically assigned to the mapped role in Sitefinity CMS.

      For example, enter groups

      For example, enter role
3. Save your changes.

      For example, enter role
   3. In Claim value, enter the value of the external claim.
      For example, enter sitefinity.adfs\Domain Users. This means that a user with claim role is logged in as a domain user.
   4. In Mapped roles, enter a comma separated list of Sitefinity CMS roles that the claim will be mapped to.

4. Save your changes.
5. Restart the application.

NOTE: The types of all claims coming from external providers are updated according to the mappings specified in the following file: https://github.com/IdentityServer/IdentityServer3/blob/master/source/Core/Configuration/Hosting/ClaimMap.cs
For example, if you have claim type returned from the ADFS:
http://schemas.microsoft.com/ws/2008/06/identity/claims/group
and mapping:
{"group", "http://schemas.microsoft.com/ws/2008/06/identity/claims/group"}
you will need to map just group as claim type. For custom claims you must map the complete claim - for example, http://schemas.microsoft.com/ws/2008/06/identity/claims/customclaim.
