  • A new quick way to set up a simplified SharePoint Extranet is BusinessGuest : http://www.business-guest.com
    A smart way to set a bridge between the internal SharePoint users and documents and the external partners through their email and a secure sharing area.

  • There are many Intranets solutions on the market, however if you are looking for a solid SharePoint based Intranet solution, check out SharePoint Implementeds' product. I think it's the best solution out for the price.They seem to have put a lot of thought into usability and filling in gaps that you would not know exsist in sharepoint until you start your implementation.

    They offer a turnkey solution which provides a custom Home Site, Department Sites and Project Sites, installation, configuration and training all under $5,000 and even have a source code option.

    One thing that I would love to see that they dont have now is a hosted solution

    You can get more details at http://sharepointimplemented.com/AwesomeIntranetGorilla.html

  • Very informative. Do you know of a script I can use to automate the upload vendors into AD LDS? I'm using it on WinServer 2008 for SP2010.

  • Nice article.. There's definitely a lot to be learnt with claims based auth. I've setup SharePoint 2007 Extranet's with AD LDS as the Auth Provider which has worked well, and I'm sure SP2010 extends that even further... the learning begins :)

  • So today we are going to define an extranet and cover …
  • Lets look at three common network topologies …
  • Authentication returns the security principal in the HttpContext.UserIIS AuthenticatesFBA requires authentication providers to implement the Membership Provider interfaceWebSSO requires authentication providers to implement the Membership Provider interface including an HTTPModule for the WebSSO ProviderMembership Provider:GetUser( string )GetUserNamebyEmailFindUsersbyEmailFindUsersbyNameRole manager: RoleExists, GetRolesForUser, GetAllRolesWebSSOHTTPModule: AuthenticateRequest Uses user auth cookie to set HttpContext.User with security principalEndRequest Used to catch the 401 responses from WSS, turns them into 302 redirect for auth to the WebSSO logon server.
  • Classic – Windows Native (NTLM, Kerberos). SharePoint consumes the NT token into an SPUser.Claims – Windows (NTLM, Kerberos), FBA (LDAP, ASP.Net/SQL), SAML (ADFS, WSTrust, WSFederation)Claims authentication for Microsoft SharePoint Server 2010 is built on Windows Identity Foundation. Windows Identity Foundation Framework is a set of .NET Framework classes that are used to implement claims-based identity.
  • Client is using a web browser. The client makes a web request (HTTP GET)SharePoint responds with a 401 Unathenticated and 302 Url to authenticateThe Authentication request is submitted to, and processed by, the local STS or another SAML compliant Identity provider, such as LiveID.The identity provider validates the identity and returns the security token (NT Token/SAML Token)Does SharePoint trust the token? The SharePoint (relying party) STS finds the policy for the requesting Web application in the policy store and creates a token for the requesting user using identity assertion values in the attribute store. Token augmentation, we add additional claims. A valid security token (new SharePoint SAML token) is returned to the user and then submitted to the Web application. The Web Browser requests the SharePoint resource with the Shareoint security token. SAML token is converted into an SPUser.Note there are two different tokens: One from Identity Provider, another from SharePoint.
  • Mixed Mode Authentication – (MOSS 2007) Single SharePoint Web Application, extended IIS Applications with different Urls and authentication.Multi-Authentication - Single SharePoint Web Application with more than one authentication provider.
  • Different scheme for different protocolsProtecting access from different channelsAnonymous web sites

    3. 3. Extranet - Definition<br />A web application that is shared with external users, such as partners, vendors, and customers<br />Common attributes for an extranet:<br /><ul><li>Sharing a private network or secured network
    4. 4. Requires authenticated access, but the identity of the consumer is not always known

Has better security controls than an Internet Web application but usually less secure than the Intranet Web application </li></li></ul><li>Common Extranet Scenarios<br />Line of Business Applications<br />Collaboration<br />Static Content or Publishing<br />Isolate and segregate internal data.<br />Authorize to use only sites and data that are necessary for their contributions.<br />Restrict partners from viewing other partners’ data.<br />Target Content<br />Segment content <br />Limit content access and search results based on audience.<br />Remote Employees<br />Partners<br />Vendors & Customers<br />

    10. 10. Security Terms<br />Authentication is the mechanism whereby systems may securely identify their users<br />Creates an identity for security principal<br />Who am I?<br />Authorization is the mechanism by which a system determines what level of access a particular authenticated user should have to secured resources controlled by the system.<br />Determines what resources an identity has access to<br />What can I access?<br />
    11. 11. SharePoint Authentication<br />SharePoint does not authenticate<br />Windows authentication via Windows server and IIS (Kerberos/NTLM)<br />FBA via ASP. NET and authentication providers (SQL, LDAP, etc.)<br />Web SSO via Active Directory Federation Services (ADFS) and other Identity Management Systems<br />SharePoint creates user profiles<br />SPUser object represents security principal<br />User Profile List in Site Collections track user profiles<br />
    12. 12. SharePoint 2010 Security<br />SharePoint 2010 changes authentication<br />Uses classic mode and claims based authentication<br />Classic mode is SharePoint 2007 style legacy mode<br />Claims-based authentication is the new security model<br />What are the benefits?<br />Claims decouples SharePoint from the authentication provider<br />Allows SharePoint to support multiple authentication providers per URL<br />Identities can be passed without Kerberos delegation<br />Allows federation between organizations<br />ACLs can be configured with DLs, Audiences and OUs<br />

    14. 14. Claims-Based Terminology<br />Identity: security principal used to configure the security policy<br />Claim (Assertion): attribute of an identity (such as Login Name, AD Group, etc.)<br />Issuer: trusted party that creates claims<br />Security Token: serialized set of claims (assertions) about an authenticated user.<br />Issuing Authority: issues security tokens knowing claims desired by target application (AD, ASP.NET, LiveID, etc.) <br />Security Token Service (STS): builds, signs and issues security tokens<br />Relying Party: application that makes authorization decisions based on claims<br />
