I have excel which connects to analysis service by http://localhost:port/xmla that connect to jetty server which is running on diff server. I want to enable window authentication that will user details for window active directory send to the server to validate.
But the problem if I using radio button that is "use window auth" it is not sending the credential to the server.
To do that we need to enable window integrated security.
I want to know in which layer the credential will be authenticated do we need to write ntlm protocol logic at server side or do we have to write any code to windows level.
Thanks in advance, please help me on this.
You need to have the SSAS to use AD for users. Then you need to add the active directory users to the Cube you are trying to access. You can either create a role and add the users there or you can add the directly to the cube security. The users are added with domain\sAMAccountName to the SSAS. Then to authenticate you use the sAMAccountName and the password (if you created the users manually the username and the sAMAccountName are usually the same).
In excel you write the credentials either in the connection string or in the dialog that it shows. And you input something like
Server: http://localhost/xmla
User: Domain\sAMAccountName (from the AD)
Password: the password :)

I want to automatically authenticate, 'active directory users', which are logged in to their windows, in my applications.
in short, i want SSO for my applications using windows credentials.
**Client is React and back-end is Java 8 and Spring 4.1.2 and Spring Security is 3.2.5.
I already authenticate and search 'active directory users' in my applications, using spring LDAP 3.2.5.
but users should submit their username and password when they use browser.
I have read about 'Integrated Windows Authentication' (IWA), 'Kerberos', 'NTLM'.
should I use NTLM instead of LDAP ???
or, should I use Kerberos ???
or, should I use ADFS ???
should I config anything in active directory for that ???
**I cant config anything in active directory
should I get windows credentials programmatically in react and send it to server and from server I should send that credentials to active directory to verify it ???
I don't know but, should I say any thing in my 'HTTP response' to 'HTTP OPTION Request' to force browser to set windows credentials in next request ??
and, thanks for your time.
There are a couple ways to do this:
Windows Authentication
This is best for the user as it is a seamless login. If the website is trusted, then the browser will automatically send the credentials of the currently-logged-on user to the site.
In this case, the web server (Tomcat in this case) handles the authentication and passes the credentials to the application. If you were using IIS and Windows, the setup would be super easy. But with Tomcat on Linux, it's a little harder. You need to setup kerberos, which requires setting up SPN (Service Principal Name) values on the domain so that your server is trusted on your domain to authenticate. The full instructions for setting this up in Tomcat 8 are here: Windows Authentication How-To
Once that is setup, your website needs to be trusted by the browsers. If your site is recognized as an intranet site, then this should already be true. If not, then your site's domain needs to be added to the Trusted Sites in the Internet Options on the client computers. This can also be done via Group Policy. That will work for IE and Chrome. Firefox uses its own network.negotiate-auth.delegation-uris setting.
Forms Authentication
Another way is to use a login page to ask the user for their username and password, then authenticate them via LDAP in your Java application code. I will assume you know how to setup a login page, so you just need to know how to verify the credentials. You can use the answer here for that code. That answer has the code in a console app, but you can pull out the code that takes the username and password and verifies it.
This is arguably easier to setup, but at the cost to the user.
I am trying to use java code mention on link: http://www.nexttutorial.com/faq/azureAD/1/Azure-active-directory-graph-api-user-authentication-in-java - but I get below error:
java.util.concurrent.ExecutionException: com.microsoft.aad.adal4j.AuthenticationException: {"error_description":"AADSTS50055: Force Change Password.\r\nTrace ID: 7596cf92-f3d6-4baf-a0c9-d166a92d1500\r\nCorrelation ID: 8cccb074-4ae4-4c9b-932b-1f4ddcb514cb\r\nTimestamp: 2017-05-05 08:20:28Z","error":"user_password_expired"}
I haven't used the Java APIs, but I can tell you two things that are the core of the problem:
The user's password has expired
You are using Resource Owner Password Grant flow
You need to change the application to instead show a browser window so the user can reset their password. If you just want to test the code as is, you can open a new Incognito/private/InPrivate window and sign in to e.g. portal.azure.com with the user. That will allow you to make sure they have a working password.
But I would advise against using that sign in flow because of potential problems like this one.
The reason you get the error is that the user needs to set a new password, but the flow you are using cannot support that scenario. It also cannot support the scenario where the user account has MFA enabled/is a Microsoft account etc.
And by the way, if this app is intended not to be used by a user, but just run as is, I would suggest making it a daemon with application permissions on the necessary APIs and then use client credentials flow for authentication. No user account needed then, since the app has the needed rights.
I need to develop a web application for the Intranet users. I don't want them to enter the login credentials each time they visit the site. It should be automatically loaded from the System Username and Password.
I have successfully implemented functionality which prompt user name and password registered with active directory and validate against LDAP. I need some tips to login directly from intranet website without prompt username & password.
Here is my queries, please let me know your suggestion.
Is it compulsory to set SPN?
Do we need to create separate keytab file for each client? In my organization, there is around 800 people are working so should I need to add all client principal in keytab file & copy to client machine to perform autologin.
I have tried many API's like JESSO, Waffle, Spring Kerberos, SPNGO but failed to implement auto login.
If you want to use Kerberos/SPNEGO (which would be my recommendation) you do have to set up SPN. And you only need one keytab for AD domain. Are you running your Java program on some app server, like Weblogic, or as a standalone program? Servers do have security framework that you could use, while for standalone program you'd have to do a bunch of stuff manually.
I've found that the easiest way to do this is to use Atlassian's Crowd (https://www.atlassian.com/software/crowd/overview) instead of implementing it yourself. It's a commercial product, but last time I checked, it was dirt cheap, and it just works.
i want to implement SSO in an application for that i have a SiteMinder policy server at the application which provide the login (say application 1) and also have installed the Siteminder webagent on the server of other application which am going to login through SSO (say application 2). This siteminder thing is already done by some other team. Now i want to get the siteminder session and from that session i want the HTTP_SM_USER this is all with the help of WebAgent. After getting the user i want to validate the user against the DB of 2nd application. Can anyone guide me how can i proceed with this work ?
The SM agent usually adds an HTTP header with the user ID to the incoming request. You can inspect this header in your code to determine the user. Note that this header does not come from the browser, the SM agent inserts it before the request is handed to your application.
I am getting confused.
I have to write an Java Serverapplication for an mobile application. We have our own user management in that application, meaning the user can register and login on our servers without using an OAuth-Provider at all.
Now I want the user to be able to alternativly register via an OAuth Provider.
These are the options I see:
Let the user register local only.
Advantage:
The mobile applications can use the frameworks which are able to login and retrieve an access token for our application
Everything is prestyled by the platform itself, so no GUI work on that
Disadvantage:
How does the server know if the user is logged in or not? One way to figure that out could be to send the access token to the server and let the server start a request to the provider to check if the token is valid or not.
For the registration I have to send all user information which the client got from the provider to our servers.
I dont like this option, cause I would send Userdata and Accesstoken arround. Yes, it would be crypted via https of course, but it just feels wrong.
Let the user register via our servers
The user requests the OAuth provider itself to retreive the code with which you could request the access token.
Send this code to the server and let the server retreive the acess token.
Advantage:
The Server can be sure now, that the user is logged in
The server can retreive all user specific information about the user (such as username etc) from the OAuth provider itself, without sending the arround.
On a login you can repeat this, to make sure that the user is logged in correctly
Disadvantage:
I have to write the OAuth connectors (or using some library for that)
We are not able to use the sdk's, cause they're just returning the actual access token.
We still prefer the first option (register local only)
Because
they WANT to use the sdks. "'cause everyone does it."
If the user would start the application the first time and he was logged in already (with i.e. the FB client), he just has to accept the scopes, we setted up for our application.
Easier to handle the actual login, cause the sdk's where made for it
Does anyone know how to do something like that correctly? Both solutions seem a bit wrong to me.
