Dear everyone,

I have a system whose authentication and authorization depends on an Active Directory. The system does perform well with the AD except for just a constraint. For the system to work properly on a given machine where the system never been installed on I have to manually map the active directory server on the machine, for example if the OS is windows 7 or above I have to go into Credential Manager in control panel and set the server name and account to login to. This has to be done per installation. I want to avoid this situation.

Thanks

You have to set credentials somehow. Either through code or this way or prompt the user.

Solution 1

Try replacing your Authentication method.

C#

private bool Authenticate(string userName,
    string password, string domain)
{
    bool authentic = false;
    try
    {
        DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain,
            userName, password);
        object nativeObject = entry.NativeObject;
        authentic = true;
    }
    catch (DirectoryServicesCOMException) { }
    return authentic;
}

Does the code will avoid the situation that I'm experiencing? Because the code I have is working fine with the AD authentication, once a credential mapping is done, it only fails for the first time, if the credential is not mapped.

Well I only wrote one app that need AD authentication and that was a few years ago.
Back then I was told to do it this way because then you can add the username and password to an encrypted config file. So if the username and/or password changes you can just send a new encrypted config file to everyone using the program.
I'm not to sure what you do after the authentication process but I'm sure this code will work. Give it a try and if it doesn't I'll see if I can help you find another solution ;)
