c# - WindowsPrincipal.IsInRole 和通用与全局活动目录组

Question

有人知道如何WindowsPrincipal.IsInRole("domain\role")使用 Active Directory 通用组吗？

假设当前用户是名为 domain 的域中名为 Role 的组的成员，并且 Role 组是 Active Directory 中的全局组。然后以下代码将产生result = true：

WindowsPrincipal wp = new WindowsPrincipal(WindowsIdentity.GetCurrent());
bool result = wp.IsInRole(@"domain\Role");

但是，如果角色组更改为通用组，则代码会产生result = false。

Answer 1

我发现我的问题没有很好的答案，我必须做的是编写一个新的 Principal 类，它扫描用户所属的所有组的目录，并递归扫描所有这些组以解决组中组成员资格。为有相同问题的用户提供的代码。这不是我写过的最简洁的代码，但至少它有效。

像这样使用：

var wp = new WindowsPrincipalEx(WindowsIdentity.GetCurrent());
result = wp.IsInRole(@"domain\role");



public class WindowsPrincipalEx : IPrincipal
{
    // Dictionary to store all groups, key = uppercase groupname, value = groupname as entered in AD
    private Dictionary<string,string> completeGroupList = new Dictionary<string,string>();
    // Private vars
    private WindowsIdentity identity;
    private string domain;

    // Identity property
    public IIdentity Identity
    { 
        get { return identity; }
    }

    // Constructor, accepts identity
    public WindowsPrincipalEx(IIdentity identity)
    {
        this.identity = (WindowsIdentity)identity;
        // Find domain name and store it for filtering purposes
        if (identity.Name.Contains('\\'))
            this.domain = identity.Name.Substring(0, identity.Name.IndexOf('\\') + 1);

        // Find all groups this user belongs to, and store the list for later use
        getRoles(completeGroupList);
    }

    public bool IsInRole(string role)
    {
        // Remove domain
        if (role.StartsWith(domain, StringComparison.CurrentCultureIgnoreCase))
            role = role.Substring(domain.Length);
        return completeGroupList.ContainsKey(role.ToUpper());
    }

    private void getRoles(Dictionary<string,string> groupList)
    {
        // Find username and remove domain
        string name = Identity.Name.Replace(domain,"");

        // Find user in AD
        DirectorySearcher search = new DirectorySearcher("(&(sAMAccountName="+name+")(objectCategory=user))");
        search.PropertiesToLoad.Add("memberof");

        SearchResult result = search.FindOne();
        if (result != null)
        {
            // Add all groups to the groupList dictionary
            foreach (string s in result.Properties["memberOf"])
            {
                string[] elements = s.Split(new char[] { ',' });
                foreach (string e in elements)
                    if (e.StartsWith("CN=", StringComparison.CurrentCultureIgnoreCase))
                    {
                        if (!groupList.ContainsKey(e.Substring(3).ToUpper()))
                            groupList.Add(e.Substring(3).ToUpper(),e.Substring(3));
                        break;
                    }
            }
        }

        // Scan through all groups found, and find group on group memberships recursevly
        foreach (var ng in groupList.ToArray())
            getRolesInRoles(groupList, ng.Key);
    }

    private void getRolesInRoles(Dictionary<string, string> groupList, string roleName)
    {
        string name = roleName.Replace(domain, "");

        // Find group in AD
        DirectorySearcher search = new DirectorySearcher("(&(cn="+name+")(objectCategory=group))");
        search.PropertiesToLoad.Add("memberof");

        SearchResult result = search.FindOne();
        if (result != null)
        {
            // Add all groups to the groupList dictionary
            foreach (string s in result.Properties["memberOf"])
            {
                string[] elements = s.Split(new char[] { ',' });
                foreach (string e in elements)
                    if (e.StartsWith("CN=", StringComparison.CurrentCultureIgnoreCase))
                    {
                        if (!groupList.ContainsKey(e.Substring(3).ToUpper()))
                        {
                            groupList.Add(e.Substring(3).ToUpper(),e.Substring(3));
                            getRolesInRoles(groupList, e.Substring(3));
                        }
                        break;
                    }
            }
        }
    }
