C# - Forms Authentication Against Active Directory - LDAP Protocol

Jan 27, 2011

I need to create a web page that authenticates users against an existing active directory. The domain is actually a cloud computing configuration where there is a domain controller and multiple other servers on the stack.

I understand that objects from the System.DirectoryServices namespace can be used. However, I cant seem to path the code to the active directory through the LDAP://domain.com address. There doesnt seem to be any communication going on. I suspect there is some initial configuration necessary or security measures blocking the communication.

I am working with this example from MSDN: http://msdn.microsoft.com/en-us/library/ms180890(v=vs.80).aspx.

I get an error that says the server is not operational.

Active Directory/LDAP :: AD Authentication Using Forms - Dealing With Roles

Mar 2, 2010

I am not really sure if this post should go in the Security section or the Active Directory / LDAP section....with that being said I am looking for advice on how to best accomplish my goal(s), I am working with FORMS authentication, using active directory (across 2 domains). I have got authenticating working correctly based upon the article at: [URL] now - my questions:

1. What is the best way to deal with roles? What I would like to do is restrict access to my application so that only the users that are authorized to use the application can login - not everyone in the AD. My gut feeling tells me I would use an AD group for this. Furthermore, a subset of these users in this group will be allowed to access the data maintenance forms

2. Ideally, in a perfect world, I would like to write this authentication piece as a separate project - this way it could be used for multiple projects - the only thing different would be the AD groups it would be checking. Is there a way that I could set which AD groups or roles in each projects web.config?

Am I approaching this the correct way? What is typically done?

Active Directory/LDAP :: Error "Invalid Dn Syntax Specified" When Try To Use Authentication Form With LDAP

Mar 16, 2010

I tried to use Authentication form with LDAP but when I run my web application I received error: Invalid dn syntax specified. This is my code:

public bool IsAuthenticated(string domain, string username, string password)
{
// string domainAndUsername = domain + @"" + username;
string domainAndUsername = "http://localhost:389
jsmith";
// DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, password);// _path = LDAP://localhost:389/dc=example,dc=com
DirectoryEntry entry = new DirectoryEntry("LDAP://localhost:389",domainAndUsername,"rJsmitH");
try
{
Object obj = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=" + username + ")";
search.PropertiesToLoad.Add("cn");

SearchResult result = search.FindOne();

if(null == result)
{
return false;
}
_path = result.Path;
_filterAttribute = (String)result.Properties["cn"][0];
}
catch (System.Exception ex)
{
throw new Exception("Error authenticating user. " + ex.Message);
}
return true;
}

I got exception at line Object obj = entry.NativeObject; and error message is: Invalid dn syntax specified. how can i take a right dn syntax? I tried some domain name such as: LDAP://localhost:389, [URL], ... but I still get this error

Active Directory/LDAP :: Converting Old Active Directory Code To New Namespace References?

Jun 24, 2010

I am updating some CS code that was written in 2004, and that references some assemblies which extract user data from AD by query filtering on the user's title. I can't test my updated code in VS2010 because the assemblies no longer compile - the references are no longer valid (I can't create a DirectoryEntry or DirectorySearcher) so I need to work out how to replace the code with current directoryservices.accountmanagement namespace properties and methods. I have searched around but don't seem to be getting anywhere. give me some code that will work with vs 2010 to replicate the following:
