I want to connect to LDAP server using my MVC application.I don't want to use active directory. Here is my post method when I get usename and password from user:
<pre lang="c#">  [HttpPost]
        public ActionResult Login(Login model, string returnUrl)
            string pwd = model.password;
            System.Security.Cryptography.MD5 hs = System.Security.Cryptography.MD5.Create();
            byte[] db = hs.ComputeHash(System.Text.Encoding.UTF8.GetBytes(pwd));
            string result = Convert.ToBase64String(db);
            var BuildServerName = new StringBuilder();

        // setup an ldapconnection to that endpoint
        var ldapConnection = new LdapConnection(BuildServerName.ToString());

        // it looks like you have an administrative account to bind with, so use that here
        var networkCredential = new NetworkCredential(model.username, result, "dc=mnit,dc=ac,dc=in");

        // set the following to true if it's over ssl (636), if not just set it to false

        ldapConnection.SessionOptions.VerifyServerCertificate += delegate { return true; };

        // now set your auth type - I typically use 'negotiate' over LDAPS, and `simple` over LDAP
        // for this example we'll just say you're not using LDAPS
        ldapConnection.AuthType = AuthType.Basic;

        ldapConnection.SessionOptions.ProtocolVersion = 3;

It throws an error at
which is: The distinguished name contains invalid syntax. What should I do in this?

What I have tried:

When I change
it returns error

The LDAP server is unavailable.

. Is there any other way to connect and check username and password through ldap.
