与UserPrincipal.GetAuthorizationGroups错误（）方法 [英] Error with UserPrincipal.GetAuthorizationGroups() method

问题描述

我现在用的是UserPrincipal类的GetAuthorizationGroups方法，在Web应用程序中有一个问题。

I am having an issue using the GetAuthorizationGroups method of the UserPrincipal class in a web application.

使用下面的code，我收到试图获取授权组，一个错误（5）发生

Using the following code, I am receiving "While trying to retrieve the authorization groups, an error (5) occurred"

PrincipalContext context = new PrincipalContext(ContextType.Domain, null, "DC=MyCompany,DC=COM", "username", "password");
UserPrincipal p = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, "joe.blogs");
var groups = p.GetAuthorizationGroups();

我相信这code工作在一定程度上。

I believe this code works to an extent.

• 当我查看上下文对象，我可以看到服务器和用户名/密码已在对象正确地解析
• 当我查看p对象，我可以看到AD细节都被填充像电话号码等。

下面是错误的堆栈跟踪。

Here is the stack trace from the error.

[PrincipalOperationException: While trying to retrieve the authorization groups, an error (5) occurred.]
   System.DirectoryServices.AccountManagement.AuthZSet..ctor(Byte[] userSid, NetCred credentials, ContextOptions contextOptions, String flatUserAuthority, StoreCtx userStoreCtx, Object userCtxBase) +317279
   System.DirectoryServices.AccountManagement.ADStoreCtx.GetGroupsMemberOfAZ(Principal p) +441
   System.DirectoryServices.AccountManagement.UserPrincipal.GetAuthorizationGroupsHelper() +78
   System.DirectoryServices.AccountManagement.UserPrincipal.GetAuthorizationGroups() +11

通过从PrincipalContext构造函数删除用户名和密码信息，并改变applicationpool（在IIS7），以相同的用户（[e-mail]）运行 - 以下code ++工程

By removing the username and password details from the PrincipalContext constructor and changing the applicationpool (in iis7) to run as the same user ([e-mail]) - the following code works.

PrincipalContext context = new PrincipalContext(ContextType.Domain, null, "DC=MyCompany,DC=COM");
UserPrincipal p = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, "joe.blogs");
var groups = p.GetAuthorizationGroups();

我需要得到code。在第一个例子中的工作 - 我不想要运行的应用程序池作为域用户只是为了得到这个code工作

I need to get the code in the first example to work - I do not want run the application pool as a domain user just to get this code working.

我处理了这个相同的问题。查看类似的问题的讨论。 http://stackoverflow.com/a/8347817/2012977

I dealt with this same problem. See discussion on similar question. http://stackoverflow.com/a/8347817/2012977

解决方案是如下：

public List<GroupPrincipal> GetGroups(string userName)
    {
        var result = new List<GroupPrincipal>();
        PrincipalContext ctx = GetContext(); /*function to get domain context*/
        UserPrincipal user = UserPrincipal.FindByIdentity(ctx, userName);
        if (user != null)
        {
            PrincipalSearchResult<Principal> groups = user.GetAuthorizationGroups();

            var iterGroup = groups.GetEnumerator();
            using (iterGroup)
            {
                while (iterGroup.MoveNext())
                {
                    try
                    {
                        Principal p = iterGroup.Current;
                        result.Add((GroupPrincipal) p);
                    }
                    catch (PrincipalOperationException)
                    {
                        continue;
                    }
                }
            }
        }

        return result;
    }
