4. Say What?  SSO  IWA  Classic Authentication  Claims Authentication  AuthN  AuthZ  IdP  RP / SP  ADFS  HRD  SAML  WS-Fed  SaaS  IDaaS

5. Answers:  SSO = Single Sign On (SSO)  IWA = Integrated Windows Authentication  SharePoint Classic Authentication  SharePoint Claims Authentication  AuthN = Authentication  AuthZ = Authorization  IdP = Identity Provider (Trusted IdP)  RP = Relying Party / SP = Service Provider  ADFS = Active Directory Federation Services  HRD = Home Realm Discovery  SAML = Security Assertion Markup Language  WS-Fed = WS-Federation  SaaS = Software as a Service  IDaaS = Identity as a Service

6. SSO Defined  End user logs in once and seamlessly can access many different web applications without needing to re- authenticate to each web application.  “Logs in once” could mean a workstation login, or a browser login.  It is NOT what I call “SAME Sign On” – using the same username each time to log into many different web applications.

7. The 3 SharePoint Doors  Authentication Options 1. Windows Authentication ○ Classic (domain\UserID) OR Claims (i:0#.w|domain\UserID) 2. Forms Authentication (i:0#.f|provider|UserID) ○.net membership provider (LDAP, SQL, Custom) 3. Trusted Identity Provider (c:0#.t|provider|IdentifyerClaim) ○ WS-Federation / SAML  If >1 door enabled, users see “picker page”.

8. Users SharePoint Identity  Each AuthN option is associated 1:1 with a users identity.  The Same user could be represented as 3 different identities to SharePoint depending on HOW the user authenticated to SharePoint. 1. (domain\eraff) OR (i:0#.w|domain\eraff) 2. (i:0#.f|provider|eraff) 3. (c:0#.t|provider|eric.raff@outlook.com) Having 3 options enabled at the same time is not common, but having 2 is.

9. Windows Authentication  Been around for years  401 challenge response – NTLM, Negotiate (Kerb)  Both Classic and Claims  Microsoft “bubble”  Every host name requires AuthN  NOT an internet friendly solution Browser/Computer must be able to access AD Domain Controller directly.

10. IWA Browser Matrix Browser Prompt HELL!

11. Forms Authentication .net membership provider LDAP identity store SQL identity store Custom  SharePoint collects user credentials and verifies them against identity store.  Must update 3 web.config files – tedious

12. Trusted Identity Provider  The Future of SSO – Web friendly using Federated authentication approaches  SharePoint NOT involved in AuthN  SharePoint IS still doing AuthZ  SharePoint is a Relying Party to an external “Trusted Identity Provider” (IdP) Anything that supports WS- Federation/SAML ○ ADFS, Windows Azure Access Control, Okta, PingIdentity, OneLogin etc.

13. Trusted IdP – the ugly  No name resolution OOTB – will affect how you authorize users in SharePoint.  MUST still enable Windows AuthN (claims) for core SP services (search)  Picker page – may need custom login page.  Possible Home Realm Discovery (HRD) issues if IdP have multiple AuthN sources.

16. And Your IdP Is….  The heart of any SSO Architecture.  Picking an IdP should be carefully considered.  Lots of options with rapidly changing and evolving landscape.  Depends on company needs, culture, applications that need to participate, legacy apps etc.

17. IDaaS  Can significantly simplify an SSO deployment and implementation.  Will likely have a role in your future to some degree.  Bringing greater security offerings to table such as Multi-Factor Authentication (MFA), real time risk analysis, Mobile integration etc.

19. Bringing it Together  Is there any current SSO technology involved?  What web applications do you want to participate in SSO? SharePoint Office 365 SaaS providers Desktop Authentication (IWA)  Do you want Web SSO or Desktop + Web SSO?  What Authentication method should you use for SharePoint?
