我有一個MVC3應用程序具有存儲在數據庫中的自定義成員資格提供程序和用戶/角色。用戶根據需要在應用程序中手動創建,並分配適當的角色。MVC3自定義MembershipProvider和活動目錄

我想現在擴展應用程序,以提供使用Active Directory的選項,但因爲應用程序有幾個自定義字段+表用戶FK查找,我想我仍然必須有一個定製版本的默認活動目錄成員資格提供程序。

SF上有人做過類似的事情,他們可以與我分享? 感謝

我知道這是一個老問題,但...

讓我們看看從哪裏開始

在我的web應用程序我建立了直接基於身份驗證與我的ADFS服務器的聯合聲明。我一直無法找到一個很好的教程,如何做到這一點,因爲它不是微不足道的。但是有很多關於如何使用azure ACS作爲中間人來做到這一點的參考資料。這其中將至少讓你開始:

一旦你得到這個工作,你只需要幾件事情。

在您的數據庫用戶表中添加一些可以與AD鏈接的屬性。我將AD GUID存儲在我的,但我也使用電子郵件地址作爲輔助。這使我可以在我的應用程序中創建用戶,然後讓他們通過AD進行身份驗證。我只是將他們的電子郵件作爲聲明傳回,在我的應用中將其與用戶匹配,然後將AD GUID添加到用戶。

我也利用繼承來做我的身份驗證。我的所有控制器都從BaseController繼承,所以他們獲得了這種標準的行爲。

public class BaseController 
{ 
    protected override void OnAuthorization(System.Web.Mvc.AuthorizationContext filterContext) 
    { 
     if (filterContext.HttpContext.User.Identity.IsAuthenticated) 
     { 
      //read in the claims that we got back from ADFS 
      IClaimsPrincipal icp = Thread.CurrentPrincipal as IClaimsPrincipal; 
      IClaimsIdentity ici = icp.Identity as IClaimsIdentity; 

      var claims = ici.Claims; 

      // This is a claim that I add manually to see if I've already synced 
      // ADFS user with DB user 
      var ppid = claims.FirstOrDefault(x => x.ClaimType == ClaimTypes.PPID); 
      if (ppid == null) 
      { 
       //query/sync user. 
       var guidString = claims.FirstOrDefault(x => x.ClaimType == ClaimTypes.Name).Value; 

       // get AD GUID 
       var userGuid = new Guid(System.Convert.FromBase64String(guidString)); 

       //look up user 
       var currentUser = UserRepository.FetchUserByGUID(userGuid); 

       //if user not found try fetch by email. 
       if (currentUser == null) 
       { 
        var email = claims.FirstOrDefault(x => x.ClaimType == ClaimTypes.Email).Value; 
        currentUser = UserRepository.FetchByEmail(email); 
       } 

       //If user is still not found create User 
       if (currentUser == null) 
       { 
        currentUser = new Models.User(); 
        BaseRepository.GetDataContext().Users.Add(currentUser); 
       } 

       //update users information using AD claim as master record 
       currentUser.ADID = userGuid; 
       currentUser.Name = claims.FirstOrDefault(x => x.ClaimType == ClaimTypes.GivenName).Value; 
       currentUser.EmailAddress = claims.FirstOrDefault(x => x.ClaimType == ClaimTypes.Email).Value; 
       currentUser.LastLoginDate = DateTime.UtcNow; 
       currentUser.LoginCount = currentUser.LoginCount + 1; 

       BaseRepository.GetDataContext().SaveChanges(); 

       // Now that you have your AD user linked to your user record 
       // in your database... 
       // Create new claims in your ADFS token that include all the roles that 
       // your user has. That way you can just piggyback on claims based 
       // authentication 
       foreach (var r in currentUser.Roles) 
       { 
        claims.Add(new Claim(ClaimTypes.Role, r.Name)); 
       } 

       // Add userid claim so that we know that this users claims have already 
       // been sync with my database 
       claims.Add(new Claim(ClaimTypes.PPID, currentUser.Id.ToString())); 
      } 
     } 

     base.OnAuthorization(filterContext); 
    } 

希望有所幫助!
