我有一个代码来检查用户是否是某个组的成员。 我在登录时使用此功能。
请注意我有域用户和本地用户,例如。 testdomain\administrator
和administrator
。
这是我使用的代码:
using (DirectoryEntry groupEntry = new DirectoryEntry("WinNT://./" + userGroupName + ",group"))
{
foreach (object member in (IEnumerable)groupEntry.Invoke("Members"))
{
using (DirectoryEntry memberEntry = new DirectoryEntry(member))
{
string completeName = memberEntry.Name;
DirectoryEntry domainValue = GUIUtility.FindDomain(memberEntry);
if (domainValue != null)
{
completeName = domainValue.Name + "\\" + memberEntry.Name;
}
Global.logger.Info("completeName from " + userGroupName + " = " + completeName);
if (userName.Equals(completeName, StringComparison.InvariantCultureIgnoreCase))
{
Global.logger.Debug("IsUserPartOfWindowsGroup returned True with username =" + userName + " , UserGroupName = " + userGroupName);
return true;
}
}
}
Global.logger.Debug("IsUserPartOfWindowsGroup returned false for username =" + userName + " , UserGroupName = " + userGroupName);
return false;
}
此代码有效,但
DirectoryEntry domainValue = GUIUtility.FindDomain(memberEntry);
在我看来,在探查器中花了很多时间。是否有更好/更快的方法来处理这个问题?
public static DirectoryEntry FindDomain(DirectoryEntry memberEntry)
{
if (memberEntry.Parent != null)
{
if (memberEntry.Parent.SchemaClassName.Equals("domain", StringComparison.InvariantCultureIgnoreCase))
{
return memberEntry.Parent;
}
}
return null;
}
另一种方式:
DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, userName, Password);
DirectorySearcher mySearcher = new DirectorySearcher(entry);
mySearcher.Filter = "(&(objectClass=user)(|(cn=" + userName + ")(sAMAccountName=" + userName + ")))";
SearchResult result = mySearcher.FindOne();
Global.logger.Info("result == " + result.Path);
foreach (string GroupPath in result.Properties["memberOf"])
{
if (GroupPath.Contains(adminGroupName))
{
Global.logger.Info(compUsrNameForEncryption + "exists in " + adminGroupName);
}
}

这与我使用的非常接近:
public bool IsUserInGroup(string userName, string groupName)
{
using (var context = new PrincipalContext(ContextType.Machine))
{
using (var searcher = new PrincipalSearcher(new UserPrincipal(context) { SamAccountName = userName }))
{
using (var user = searcher.FindOne() as UserPrincipal)
{
return user != null && user.IsMemberOf(context, IdentityType.SamAccountName, groupName);
}
}
}
}
我还没有为本地用户测试过。逻辑在我的域中工作,我刚刚更改了PrincipalContext(ContextType.Machine)
所以现在应该查看本地用户。
不要忘记为System.DirectoryServices.AccountManagement

也许我错过了一些东西,但你不能这样做:
if(Page.User.IsInRole("GROUP NAME"))
{
// user is in group. do your thing
}
else
{
// user isn't in group
}
当我在ASP.NET上进行Active Directory身份验证时,适用于我。
编辑:这是使用Page.User.IsInRole()描述的link。但是,必须使用Windows身份验证,如果不使用Windows身份验证,则无法正常运行。
EDIT2:由于没有使用Windows身份验证,我就是这样做的:
DirectoryEntry de = new DirectoryEntry(LDAP Address,user,password);
DirectorySearcher searcher = new DirectorySearcher(de);
searcher.Filter = string.Format("(SAMAccountName={0})", user);
SearchResult result = searcher.FindOne();
bool isInGroup = false;
if (result != null)
{
DirectoryEntry person = result.GetDirectoryEntry();
PropertyValueCollection groups = person.Properties["memberOf"];
foreach (string g in groups)
{
if(g.Equals(groupName))
{
isInGroup = true;
break;
}
}
}
return isInGroup;
