Authenticating users against Active Directory

Posted by Michael Bray on December 13, 2007

string userName = loginName + "@ctiusa.com"; 
DirectoryEntry de = new DirectoryEntry("LDAP://ldapRootPath", userName, password); 
de.AuthenticationType = AuthenticationTypes.Secure; 
System.DirectoryServices.PropertyCollection props = de.Properties; 
try 
{ 
    int n = props.Count; 
    return StandardServiceResponse.SuccessResponse;   // Success 
} 
catch (Exception ex) 
{ 
    System.Diagnostics.Debug.WriteLine(ex.Message); 
    return StandardServiceResponse.InvalidCredentials;   // Error 
}
