Duplicate user for Intranet and Internet Domains

    Question

  • Hi,

    Am woring on a Portal with Intranet and Internet Access.

    For Intranet users authentication is against AD domains. This part is fine.

    For Internet users - The Security policies doesnt allow authentications against AD which is in internal network. There is a copy of AD in the DMZ tier against which the authentication has to happen. But then, the domain is completely different. We have not reached to stage of setups yet, but am afraid this would mean that because of separete domains in internal netwrok and dmz network, the user would be treated as different user when logging in on intranet Vs Internet.

    Has anyone seen this before - any thoughts/guidance would be helpful.

    Thanks.

  • Hello,

    I think having 2 AD (1 original and 1 copy) will definitely create 2 different credentials for single user. There are other options to avoid 2 credentials for 1 user such as:

    1. Set-up one-way trust from external domain to internal domain
    2. Use Azure AD FS  (see http://technet.microsoft.com/en-us/library/dn296436.aspx)
    3. Create custom STS for external user what will inject custom claim properties; and use the claim for user/group management. (see http://msdn.microsoft.com/en-us/library/ff699494(v=office.14).aspx)

    I hope it gives you some clue.

  • I did confirm that there is one way trust from external domain to internal domain. Am not sure if that can help users to authenticate against the internal AD. Can someone pls help confirm?

  • That means users on the internal domain can authenticate to services on the external domain.  If SharePoint was hosted on the external domain, that would mean you would need to configure each Web Application to allow authentication against the internal domain:
