User authentication using Digital Certificate


  • Hi,

    The SharePoint portal I'm working on has been configured to work with both forms based authentication and windows authentication, but the portal owner wants that every user uses a Digital Certificate so the portal will know that the user really is who he is saying that he is.

    Is it possible? How it works? How can I do this?

    Thanks. (Português) | (English) | |

  • As far as I know, sharepoint doesnt support it.

  • What if we define that computers must have a digital certificate installed to have their access granted? Is this possible?

  • Hi, 

    Thanks for the link, but this is a lit bit different from what I really need. This solution will provide digital signature to documents, but I need to provide digital certificates to users or client computers. (Português) | (English) | |

    According to , when you use Windows authentication in SharePoint, you can configure IIS to use client certificates:


    Authentication method

    Additional configuration

    Specialized roles


    1.    Select Windows authentication in Central Administration.

    2.    Configure IIS for certificate authentication.

    3.    Enable Secure Sockets Layer (SSL).

    4.    Obtain and configure certificates from a certification authority (CA).

    Windows Server 2003 administrator, to obtain and configure


    For detail about client certificate authentication and IIS, please refer to .
