[英]ASP.NET MVC 5 Authentication based on IIS server's Windows domain
[英]Windows Authentication issue in IIS using ASP.NET app in a multi-domain forest
我正在尝试实现一个使用Windows身份验证的基于Web的Intranet项目。 Web服务器(Windows 2012 Server)位于域A中,但我需要能够从林中任何域中的计算机访问该站点。 我只是使用域A和B中的计算机对此进行测试。
在IIS 7.0中,我启用了Windows身份验证,并禁用了所有其他身份验证,包括匿名身份验证。 在web.config中,我有:
<authentication mode="Windows"></authentication>
<identity impersonate="true" />
<authorization>
<deny users="?" />
</authorization>
经过身份验证的用户必须位于AD组“ TestGroup”中; 我出于测试目的在web.config中删除了<allow groups =“ TestGroup” />; 我还在主页上添加了一些标签来显示我的用户ID,我所属的组,“ TestGroup”的所有成员以及是否是“ TestGroup”的成员(出于调试目的)。
我相信到目前为止我所做的一切都正确。 使用web.config如下:
如果我在web.config中删除了身份部分:
如果删除授权部分并将身份部分保留在web.config中:
似乎为了能够显示正确的用户ID,我需要将模拟设置为true。 为了要求用户从域AI之外的PC登录,AI需要具有授权部分,但两者似乎都无法在域A之外的PC上正常工作。
这是我用来获取用户ID,用户组成员身份和组成员的内容:
WindowsIdentity wiUser = WindowsIdentity.GetCurrent();
string sID = wiUser.Name.ToUpper().Repl("DomainA\\", string.Empty);
string sGroupName = @"TestGroup";
List<string> lsGroups = Utils.GetUserADGroups(sID);
bool bTC = lsGroups.Contains(sGroupName);
StringCollection scGroupMembers = Utils.GetGroupMembers(Utils.DomainType., sGroupName);
static string adDomain = "USA.ABC.DEF.COM";
static string adContainer = "DC=USA,DC=abc,DC=def,DC=com";
static string adADPath = "LDAP://USA.abc.def.com";
public static List<string> GetUserADGroups(string UserName)
{
List<string> lsGroups = new List<string>();
try
{
PrincipalContext pc = new PrincipalContext(ContextType.Domain, adDomain, adContainer);
UserPrincipal up = UserPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, UserName);
PrincipalSearchResult<Principal> psr = up.GetGroups(pc);
foreach (Principal p in psr)
{
lsGroups.Add(p.Name);
}
}
catch (Exception)
{
}
return lsGroups;
}
public static StringCollection GetGroupMembers(DomainType eDomainType, string strGroup)
{
DirectoryEntry de = new DirectoryEntry(adDSADPath);
System.Collections.Specialized.StringCollection GroupMembers = new System.Collections.Specialized.StringCollection();
try
{
//DirectoryEntry DirectoryRoot = new DirectoryEntry(sADPath);
DirectorySearcher DirectorySearch = new DirectorySearcher(de, ("(CN=" + (strGroup + ")")));
SearchResultCollection DirectorySearchCollection = DirectorySearch.FindAll();
foreach (SearchResult DirectorySearchResult in DirectorySearchCollection)
{
ResultPropertyCollection ResultPropertyCollection = DirectorySearchResult.Properties;
foreach (string GroupMemberDN in ResultPropertyCollection["member"])
{
DirectoryEntry DirectoryMember = new DirectoryEntry(("LDAP://" + GroupMemberDN));
System.DirectoryServices.PropertyCollection DirectoryMemberProperties = DirectoryMember.Properties;
object DirectoryItem = DirectoryMemberProperties["sAMAccountName"].Value;
if (null != DirectoryItem)
{
GroupMembers.Add(DirectoryItem.ToString());
}
}
}
}
catch (Exception ex)
{
}
return GroupMembers;
}
我还尝试使用它来查看用户是否是该组的成员,但是如果我从域B中的PC访问该站点,则会引发错误:
public static bool IsMember(string UserName, string GroupName)
{
try
{
PrincipalContext pc = new PrincipalContext(ContextType.Domain, adDomain, adContainer);
UserPrincipal up = UserPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, UserName);
PrincipalSearchResult<Principal> psr = up.GetGroups(pc);
foreach (Principal result in psr)
{
if (string.Compare(result.Name, GroupName, true) == 0)
return true;
}
return false;
}
catch (Exception e)
{
throw e;
}
}
解决我问题的最终方法是将功能包装在以下方法中:
using (System.Web.Hosting.HostingEnvironment.Impersonate())
{
}
例如,我将原始帖子中的方法从:
public static StringCollection GetGroupMembers(DomainType eDomainType, string strGroup)
{
DirectoryEntry de = new DirectoryEntry(adDSADPath);
System.Collections.Specialized.StringCollection GroupMembers = new System.Collections.Specialized.StringCollection();
...
}
至:
public static StringCollection GetGroupMembers(DomainType eDomainType, string strGroup)
{
using (System.Web.Hosting.HostingEnvironment.Impersonate())
{
DirectoryEntry de = new DirectoryEntry(adDSADPath);
System.Collections.Specialized.StringCollection GroupMembers = new System.Collections.Specialized.StringCollection();
...
}
}
希望这可以使别人免于悲痛,因为这引起了我很多!
