I've written some code but not works it throws Exception "An operations error occurred."
code --->
DirectoryEntry dirEntry = new DirectoryEntry("LDAP path", "admin-username", "admin-password");
dirEntry.Properties["member"].Remove("username-delete");
dirEntry.CommitChanges();
dirEntry.Close();
give me some ideas to get out of this things..
If you're on .NET 3.5 and up, you should check out the System.DirectoryServices.AccountManagement (S.DS.AM) namespace. Read all about it here:
Managing Directory Security Principals in the .NET Framework 3.5
MSDN docs on System.DirectoryServices.AccountManagement
Basically, you can define a domain context and easily find users and/or groups in AD:
// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
// find the user you want to delete
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, "SomeUserName");
if(user != null)
{
user.Delete();
}
The new S.DS.AM makes it really easy to play around with users and groups in AD!
When you are already using a DirectoryEntry there is no need for PrincipalContext or UserPrincipal.
You can simply use the DeleteTree() method:
DirectoryEntry dirEntry = new DirectoryEntry("LDAP path", "admin-username", "admin-password");
dirEntry.DeleteTree();

I'm not a programmer by nature so I apologize in advance :) I'm using the code snippets from http://www.codeproject.com/Articles/18102/Howto-Almost-Everything-In-Active-Directory-via-C#39 and it has been really helpful. I'm using his method for getting user group memberships and it requires his AttributeValuesMultiString method as well. I don't have any syntax errors but when I call the Groups method via Groups("username", true) I get the following error:
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in System.DirectoryServices.dll
I have done some digging but nothing seems to really answer why I'm getting this error.

Does anyone know the best way to search for a single user within Active Directory using DirectoryServices? I have code that currently lists all sub 'OU's' under a given LDAP path but I now want to add the feature of searching for a user under the path too. Could the code just be adapted to search for users?
I have included my code that lists all users in the current OU:
DirectoryEntry Ldap = new DirectoryEntry("LDAP://" + ouselect.SelectedValue + ";" + LDAPRoot, LDAPUser, LDAPPass);
DirectorySearcher ad_search = new DirectorySearcher(Ldap);
ad_search.Filter = "(objectClass=User)";
ad_search.SearchScope = SearchScope.Subtree;
ad_search.PropertiesToLoad.Add("samaccountname");
Any pointer that anyone can offer would be excellent.

PS: the PrincipalContext has a number of different overloads for its constructor - you can also define a username/password to use to query Active Directory, and you can also define a "starting" container, if you need to. Check out the MSDN documentation for details on this.
Your code is almost there. Just change your filter to search for a particular AD Attribute, rather than all users.
ad_search.Filter = string.Format("(department={0})", department);
ad_search.Filter = string.Format("(displayName={0})", "James Doe");
ad_search.Filter = string.Format("(sAMAccountName={0})", "some.username");
I'm trying to integrate a system with Active Directory using the System.DirectoryServices.AccountManagement stuff. Our IT people have setup an AD box and my dev box is not part of this (or any) domain.
So far, I have 3 lines of code as a test:
var pc = new PrincipalContext(ContextType.Domain, "machine", "CN=Administrator,CN=Users,DC=domain,DC=com", "Password");
var user = UserPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, "Administrator");
var gp = GroupPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, "Admins");
Creating the PrincipalContext works as listed above, but if I try to use the domain name instead of the server name then I get an error : The server could not be contacted. So, I left this on the machine name.
When getting the user or group, I get an error : A local error has occurred.
For the user, I also tried this with the same result:
var user = UserPrincipal.FindByIdentity(pc, IdentityType.DistinguishedName, "cn=Administrator,ou=users,dc=domain,dc=com");
So, overall, I'm confused :(
Does anyone have any suggestions?
As a side note, I'd like to kick the programmer who thought that 'a local error has occurred' would be a useful error message!
Cheers
PS: I can use the SysInternals AD Explorer just fine from my machine and I can see the dn's I'm trying to use.
PPS: If I use machine.domain.com for the name when creating the PrincipalContext, it also fails to connect.
So this is one of those things that makes perfect sense AFTER you hack through to the solution. The problem was the Context was trying to use a Negotiated security context which is not configured. When I used SimpleBind it works just fine:
var pc = new PrincipalContext(ContextType.Domain, "machine", "DC=domain,DC=com", ContextOptions.SimpleBind, "CN=Administrator,CN=Users,DC=domain,DC=com", "Password");
Cheers
PS: A more useful error message would have saved me a days head scratching!
To do the search using the credentials of the current user, specify the domain as such:
new PrincipalContext(ContextType.Domain, "xyz.mycorp.com:3268", "DC=mycorp,DC=com");

When do I need a Domain Name and a Domain Container to create a PrincipalContext?
I create a new user successfully, and then I try to set their initial password using the following code:
newUser.AuthenticationType = AuthenticationTypes.Secure;
newUser.Invoke("SetPassword", new object[] { "somepassword" });
newUser.Properties["LockOutTime"].Value = 0; //unlock account
When it (eventually) returns, I get the following exception
System.IO.FileNotFoundException: The network path was not found
If I inspect the 'newUser' object, it has a Path attribute which looks fine to me.
I don't think my instance of AD is available over SSL though, I can only connect to it over port 389. Is that something to do with it?
Any help appreciated, I'm new to AD and struggling...
Thanks
As suggested here, you might have more success with the new and improved System.DirectoryServices.AccountManagement namespace.
// establish context for local machine
PrincipalContext ctx = new PrincipalContext(ContextType.Machine);
// find the account
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, "YourUser");
// set the password to a new value
user.SetPassword("new-top-secret-password");
user.Save();

Since you're on .NET 3.5 and up, you should check out the System.DirectoryServices.AccountManagement (S.DS.AM) namespace. Read all about it here:
Managing Directory Security Principals in the .NET Framework 3.5
Basically, add a reference to the assembly System.DirectoryServices.AccountManagement, and then you can define a domain context and easily find users and/or groups in AD:
using System.DirectoryServices.AccountManagement;
public List<GroupPrincipal> GetGroupsForUser(string username)
{
List<GroupPrincipal> result = new List<GroupPrincipal>();
// set up domain context - if you do a lot of requests, you might
// want to create that outside the method and pass it in as a parameter
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
// find user by name
UserPrincipal user = UserPrincipal.FindByIdentity(username);
// get the user's groups
if(user != null)
{
foreach(GroupPrincipal gp in user.GetAuthorizationGroups())
{
result.Add(gp);
}
}
return result;
}
The new S.DS.AM makes it really easy to play around with users and groups in AD:
