Hi,

I have to code a .dll in c# that will create/manage user in our active directory.
Everything works great, except one thing. Im not able select "Allow access" in Dial-in tab.
I try this line "newUser.Properties["msNPAllowDialin"].Add(true);". No error there with compilation or execution. But i see no change in AD.

Later if I search for this user throught c# code, i see that property msNPAllowdialin = true.

Am I missing something in my code? Or this problem is related to our AD ?

Thanks in advance for your help !
public void selectDomain(string ldapPath) {
            currentDomainDE = new DirectoryEntry(ldapPath);
            currentDomainDE.AuthenticationType = AuthenticationTypes.Secure;
        }
 
        public void CreateUserAccount(string _userName, string _userPassword, string _firstName, string _lastName,
                                      string _description, string _company)
        {
            try
            {
                DirectoryEntry newUser = currentDomainDE.Children.Add("CN=" + _userName, "user");
                newUser.Properties["samAccountName"].Value = _userName;
                newUser.Properties["sn"].Add(_lastName);
                newUser.Properties["givenname"].Add(_firstName);
                newUser.Properties["displayname"].Add(_firstName + " " + _lastName);
                newUser.Properties["description"].Add(_description);
                newUser.Properties["company"].Add(_company);
                newUser.CommitChanges();
 
                int flags = (int)newUser.Properties["userAccountControl"].Value;
                newUser.Properties["userAccountControl"].Value = (flags ^ 0x10000);
                newUser.Properties["msNPAllowDialin"].Add(true);
                newUser.CommitChanges();
                
                this.changePasswordUser(newUser, _userPassword);
 
                this.enableAccount(newUser);
 
                newUser.Close();
                this.closedDomain();
            }
            catch { .......}

AD related I believe.

It depends a little, tell us about your domain if you could? Specifically, what Functional Level is your domain set to?

Mine works when set using a small script with Functional Level set to Windows 2003 Native.

And take a look at these two articles:

There we go :)

You must switch to Native for the change to work as you expect in your existing code.

For whatever reason the attribute cannot be updated correctly using ADSI / DirectoryServices via LDAP in Mixed Mode.

Alternatively bind using the WinNT interface as described in:

http://support.microsoft.com/default.aspx?scid=kb;en-us;252398

However, there are no issues with changing to Native Mode unless you have Windows NT 4 Backup Domain Controllers on the Domain.

I will be surprise if we have a NT4 DC. So i will ask him if we can go with Native Mode.

If not, i will try the other option with the .dll and winnt provider.
Do you know where i can find the ADSI SDK on MS website? All the links I try redirect to microsoft.com/windows/

Thanks for your help !

Hmm that's a good question.

You don't seem to be able to get it any more. I know they stopped doing any work on it quite a few years ago, but that doesn't help if they're still got references to it.

You can grab the file from here though:

http://microsoftluder.dk/resources/ADSI%20SDK%205%20HTML/rtk.htm#ras

Obviously we can't vouch for the validity of the files held on the site, so use them with care.

For your information, with the modification of our domain from Windows 2000 Mixed to Windows 2000 Native, everything works great now. Thanks for your help !
