Ich fand keine gute Antwort auf meine Frage, was ich tun musste, war eine neue Principal-Klasse zu schreiben, die das Verzeichnis nach allen Gruppen durchsucht, zu denen der Benutzer gehört, und rekursiv all diese Gruppen scannt, um Gruppen zu lösen. Gruppenmitgliedschaften. Code für Benutzer mit demselben Problem. Es ist nicht der prickiest Code, den ich geschrieben habe, aber zumindest funktioniert es.
Verwendung wie folgt aus:
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;
}
}
}
}
}
