Authetication from a Kerberos authenticated machine to an NTLM server
You can't. Kerberos has nothing to do with NTLM. Absolutely nothing. NTLM is Windows only. All you can do is to login with your Windows user/pass and perform NTLM auch. Though I would strongly recommend making your SharePoint Kerberos-capable which is less than an hour work.

C# Active Directory authentication
I am not sure I understand AngularJS angle. If I had a regular WCF service I would use WindowsIdentity from ServiceSecurityContext.Current. http://msdn.microsoft.com/en-us/library/system.servicemodel.servicesecuritycontext.aspx ServiceSecurityContext securityContext = ServiceSecurityContext.Current; if (securityContext == null) throw new Exception("Failed to retrieve Service Security Context"); WindowsIdentity identity = securityContext.WindowsIdentity; currentUser.name = identity.Name

MVC2 Active Directory Authentication
I think the solution is in the Authentication type. Originally, I was using the following: IIS Authentication Anonymous: Disabled ASP.NET Impersonation: Disabled Forms: Enabled Windows: Disabled And in my Web.config file I was using Forms authentication. Apparently for Active Directory authentication, the type has to be Windows. Original: <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880" /> </authentication> Revised: <authentication mode="Windows" /> <authorization> <deny users="?" /> </authorization> I know this worked, but since I'm new to MVC, I could still be missing something.

Jetty - JAAS and Active Directory - Authentication Only?
Your authentication is successful. Since you want to allow all authenticated users to access everything, you still need to protect the URL pattern /* as you are doing. You can use the RegExpAuthorizationFilter (see https://wiki.apache.org/solr/SolrSecurity). Now, they don't include this class in the regular distribution. I found the code here (https://issues.apache.org/jira/secure/attachment/12572819/SOLR-4470_branch_4x_r1454444.patch) and it compiled easily. When you configure the filter, specify one arbitrary (non-existent, like /abcde) URL pattern with any role. The way it works is that it will see if the URL being requested matches this pattern. Since it doesn't, it moves forward. But there are no more rules, and access is allowed. So it requires authentication for all URLs but al

Active Directory authentication through ssl as anonymous user
I did some research and found other applications having similar issues. 1. Make sure you have imported your certificates into the keystore according to the Connect to LDAP or Other Services Via SSL instructions. 2. Make sure any certificates have been imported into the correct keystore; you may have multiple JDKs.

Active Directory Authentication using Client Certificate in ASP.NET MVC
This should work out of the box with no code. First, turn off anonymous access and basic authentication for the website and turn on integrated windows authentication and certificate integration. Then, in your asp.net application, set the auth mode to windows. Then, turn on SSL for the website and check the option "require client certificate". http://technet.microsoft.com/pl-pl/library/cc753983%28v=ws.10%29.aspx From now on, when the browser supports certificate integrated authentication and the client machine has the certificate either in the user store (IE) or in the browser store (other browsers), the browser will automatically ask the user to pick up the certificate. My advice is to start with integrated windows authentication over SSL but without certificates (do not check "Requ

Drupal 7 and LDAP authentication with Active Directory
Your problem is the baseDN apparently. on the first error, the authentication fails (login or password are wrong). As to the second one, there is some other problem in your configuration. Have you checked everything? Enabled the ports in iptables? Because it seems to fail when it tries to contact with the server (bind_method; Authentication Server or Configuration Error). I hope this helps at least to clarify the situation a little bit :)

Tomcat 6 - authentication through active directory with encrypted password
I think your only alternative is to subclass JNDIRealm and make a new attribute that will have some sort of encrypted connection password. The password can't be hashed (with, e.g. MD5 as you specify) because hashes are one-way--there's no undoing a hash--and Tomcat needs the password in its original unhashed form to authenticate against the AD installation. If you use a reversible encryption in your JNDIRealm subclass, then when Tomcat needs the password you can decrypt the password and pass it along.

AccountController not redirecting to the correct page when using Active Directory authentication
Before you redirect to action, issue a FormsAuthentication.SetAuthCookie. This should override the default behaviour of the return URL: Its also worth noting that the bool in SetAuthCookie(string username, bool createPersistantCookie) can be used to remember the user. For this example I have set it to false. try{ LDAPAuth.LDAPQuery(model); FormsAuthentication.SetAuthCookie(model.UserName, false); return RedirectToAction("Homepage", "HomePage"); }

how to check the username in Active Directory in WPF
Your process has to be run under active directory user otherwise you should provide also active directory user credentials when creating PrincipalContext. This is simple code to find user by userName: var context = new PrincipalContext(ContextType.Domain, "yourDomainHost"); var userInfo = UserPrincipal.FindByIdentity(context, userName); EDIT: if you need to use directory searcher you can try this method: bool ContainsUser(string domain, string userName) { string ldapBase = string.Format("LDAP://{0}", domain); // in case if process is not running under AD user use: new DirectoryEntry(ldapBase, "userName", "password") using (var entry = new DirectoryEntry(ldapBase)) { using (var searcher = new DirectorySearcher(entry))

Javascript/Ajax NTLM Authentication
As far as I have seen, no one has implemented Windows Integrated/NTLM auth with AJAX, although it should be possible (I'm considering doing it for a current project to combine form authentication with the WindowsTokenRoleProvider) The basic workflow should breakdown like this (based on articles here and here): do a GET request with a base64-encoded type-1 NTLM message in the "Authorization" header take the base64-encoded type-2 NTLM message out of the "WWW-Authenticate" header in the 401 response. perform the NTLM operation on the noonce recieved in the previous step (sorry I don't have a code example yet) perform a final GET with a base64-encoded type-3 NTLM message in the "Authorization" header. This should return a 200. NTLM auth over HTTP is more of a CHAP implementation using HTT

SOAP and NTLM Authentication between Debian an IIS Server
For information we finally found a workaround to resolve the problem. The problem was due to the fact the IIS Server needed an AD Login / Password to let our PHP application connect to the Web Service. What we did was using an other url to reach the Web Service, an URL needing an "anonymous" account. It means the account is defined by the application itself and not the AD. Consequently we don't need to use NTLM authentication, where the problem was coming from.

Check if Active Directory Group exists in current container using C#
You seem to be under the (false) assumption that a entry.Children.Find() will do a recursive search through your entire directory - it does not do that. So, either you need to bind to the actual container where that group should be located, and then check its immediate children for existence of your group: DirectoryEntry entry = new DirectoryEntry("LDAP://YourServer/OU=SubOU,OU=TopLevelOU,dc=test,dc=com", userName, password,AuthenticationTypes.Secure); try { DirectoryEntry childGroup = entry.Children.Find("CN=TestGroup2"); // create group here } catch (DirectoryServicesCOMException exception) { // handle the "child not found" case here ... } or then you need to do a directory search for your group which works recursively through your entire directory (and thus will

Mixing NTLM with Forms Authentication in IE (Empty POST issue)
I wrote about this issue here: http://blogs.msdn.com/b/ieinternals/archive/2010/11/22/internet-explorer-post-bodies-are-zero-bytes-in-length-when-authentication-challenges-are-expected.aspx Your question omits important information which makes it hard to troubleshoot. You should never see the problem described with the literal URLs you've used, because IE uses protection spaces to decide whether a site is going to demand credentials via a HTTP/401 and example.com/ and example.com/foo/ are different protection spaces. It would be very helpful if you could share a Fiddler log of this scenario for better troubleshooting.

Simple User/Password authentication for HiveServer2 (without Kerberos/LDAP)
In essence, you have to provide a java application that can perform your authentication. Maybe you're authing to a mysql or postgres database, or a flat file, etc. You need to provide a jar that can implement the org.apache.hive.service.auth.PasswdAuthenticationProvider interface. A simple example: package org.apache.hive.service.auth.PasswdAuthenticationProvider.SampleAuth; import java.util.Hashtable; import javax.security.sasl.AuthenticationException; import org.apache.hive.service.auth.PasswdAuthenticationProvider; /* javac -cp $HIVE_HOME/lib/hive-service-0.12.0-cdh5.0.0-beta-2.jar SampleAuthenticator.java -d . jar cf sampleauth.jar hive cp sampleauth.jar $HIVE_HOME/lib/. */ public class SampleAuthenticator implements PasswdAuthenticationProvider { Hashtable<String, Str

Automate download of a dynamically generated file after NTLM Authentication using vbscript/java
You can't authenticate a user without providing credentials. Manually download the file once while inspecting the session with something like Fiddler. That will reveal the headers required for the POST request. Then automate the request like this: url = "http://..." user = "..." pass = "..." credentials = "username=" & user & "&password=" & pass Set req = CreateObject("Msxml2.XMLHttp.6.0") req.open "POST", url, False req.setRequestHeader "Content-Type", "application/x-www-form-urlencoded" req.send credentials Modify credentials according to what Fiddler revealed. You may need to encode the values (user and pass in the example above) with something like this: Function Encode(ByVal str) Set re = New RegExp re.Pattern = "[^a-zA-Z0-9_.~-]" enc = "" For i = 1 To L

Is this HTTPS authentication protocol secure?
The security bases on the certificate you use for encryption. In general this is enough, you may also check if it is the expected certificate. In the case that you check yourself the fingerprint of the certificate you can be sure (if you use sha1 or better) that the certificate is from you and not a successful man in the middle attack. E.g. the NSA could simple create valid certificates for your domain, but AFIK it is impossible to generate a second certficate with the same fingerprint. By the way I hope that the passwords and tokes are also salted. That is important so it is impossible to see that two customers uses the same password and also it increases the complexity of the hash, that means that it will take much more time to crack such a password with a rainbow table.
