Missing authentication token for rest request

Comments

One of the most common headers is call Authorization. Wait a minute, we are talking about authentication but why the Authorization header? The distinction between authentication and authorization is important in understanding how RESTful APIs are working and why connection attempts are either accepted or denied:.

Authentication is the verification of the credentials of the connection attempt. This process consists of sending the credentials from the remote access client to the remote access server in an either plaintext or encrypted form by using an authentication protocol. Authorization is the verification that the connection attempt is allowed.

Authorization occurs after successful authentication. In other words: Authentication is stating that you are who are you are and Authorization is asking if you have access to a certain resource. I know that it is a bit confusing that in REST APIs we are using the Authorization header for doing Authentication or both but if we remember that when calling an API we are requesting an access to certain resource it means that the server should know whether it should give access to that resource or not, hence when developing and designing RESTful API Authorization header sounds just fine.

The most simple way to deal with authentication is to use HTTP basic authentication. We use a special HTTP header where we add 'username:password' encoded in base Note that even though your credentials are encoded, they are not encrypted! It is very easy to retrieve the username and password from a basic authentication.

One of the downsides of basic authentication is that we need to send over the password on every request. Also, it does not safeguard against tampering of headers or body.

Another way is to use HMAC hash based message authentication. Instead of having passwords that need to be sent over, we actually send a hashed version of the password, together with more information.

Let's assume we have the following credentials: username "username", password "secret". We could add other information as well, like the current timestamp, a random number, or the md5 of the message body in order to prevent tampering of the body, or prevent replay attacks.

Next, we generate a hmac:. Right now, the server knows the user "username" tries to access the resource. The server can generate the digest as well, since it has all information. Please note that the "password" is not encrypted on the server, as the server needs to know the actual value. This is why te name "secret" is preffered and not a "password". Even if a hacker was listening in on the conversation, they could not use the authentication information to POST data to user's account details, or look at some other users accounts, or any other URL, as this would change the digest and the hacker does not have the secret that both the server and client has.

However, the hacker could access user's account whenever it wants since it doesn't change the digest. This is why many times more information is send over, like the current time, and a nonce:. We added two extra pieces of information.

The current date and a number that we only use once nonce. The server can reconstruct the digest again, since the client sends over the nonce and date. When the date is not in a certain range of the current servers time say, 10 minutesthe server can ignore the message, as it probably is a replay of an earlier send message note: either that, or the server or clients time is wrong.One of the key principles of REST is that its stateless.

This means that the server never keeps user state. In the context of security, this aspect has impacts when implementing security. This means that authentication hints must be sent and verified at each time. For the latter, we describe how to design the resources that manages security tokens within a RESTful application.

In the past, StackMob provides a great sample of this within their plateform. HTTP provides a built-in authentication mecanism based on a username and a password. These hints are provided within the request using the header Authorization and formatted as described below:. Base64 simply means that the enclosed content is encoded using the base We can also notice that the password can consist in a token to be more robust. We mean by token an UUID.

Restlet implements such authentication within its client support thanks to the class HttpBasicHelper. Its method formatResponse shows how to format the content of the header:.

To have a look at the complete content of the class, we can use this link. As said in the name of the authentication, the latter is basic and should be used for simple scenarios. For more advanced and robust use cases, we should consider to use. The first resource allows to obtain temporary security tokens that can be used to authenticate actual calls to RESTful applications.

The following parameters are required to call the resource:. The two first parameters are generally available within your account within the application you want to access. Following code describes the content of the request to send by a REST client to obtain a temporary access token:. Some additional fields specified to the remote application can be also present.This topic covers specifics for the Azure Key Vault service.

The Azure Key Vault Service supports protocol versioning to provide compatibility with down-level clients, although not all capabilities will be available to those clients. Clients must use the api-version query string parameter to specify the version of the protocol that they support as there is no default.

Other 3xx codes may be used in the future to indicate DNS and path changes. The response body will contain detailed error explanation.

The response body will contain summarized error information. The system is designed to work behind a proxy or firewall.

Therefore, a client might receive other error codes. Azure Key Vault also returns error information in the response body when a problem occurs. The response body is JSON formatted and takes the form:. For more information on registering your application and authenticating to use Azure Key Vault, see Register your client application with Azure AD. When an access token is not supplied, or when a token is not accepted by the service, an HTTP error will be returned to the client and will include the WWW-Authenticate header, for example:.

Hi, going via java application having set up the rest high level client to use the cacert and then running the request in postman with basic auth username password. For postman, you need to pass credentials with your requests, see Basic Auth.

For the High Level rest client see the last comment here that references HttpAsyncClientBuilder where you can pass the keystore parameter. Please do go through the documentation that I linked above and see how Authentication works in Elasticsearch, it would be much helpful.

If you want to use client certificates for authentication, you need to enable and configure a PKI Realm in Elasticsearch. If you have configured Elasticsearch, please share your configuration.

curl -u es_admin -XPUT 'localhost:9200/people/person/l?pretty' -d '{"name" : "Administrator"}';

Skimmed through it, I don't see anything particularly wrong with it, but I can't verify it should work as this is not reproducible outside your specific environment. Not sure what you mean with the above, but I assume you will post some logs from the error Both from your app and Elasticsearch would be optimal as otherwise there is not much we can do.

Please don't post images of text as they are hard to read, may not display correctly for everyone, and not searchable. This makes it more likely that your question will receive a useful answer. You need to set xpack. You don't specify what's in the JKS keystore that you use in your code, but I'd thought I'd mention it should contain your cert. You need to also add your private key to your keystore, the certificate is not enough.

The current state would explain why your client can't authenticate. Unfortunately keytool doesn't offer functionality for importing a key and certificate pair so you need to create a PKCS 12 out of your pair first.

When prompted above, add a password to the PKCS 12 store as the next command depends on it. Cheers will give that a go, how would you swap that out for Client certificates?If you've got a moment, please tell us what we did right so we can do more of it.

Amazon S3 now supports the latest Signature Version 4. This latest signature version is supported in all regions and any new regions after January 30, will support only Signature Version 4. Authentication is the process of proving your identity to the system. Identity is an important factor in Amazon S3 access control decisions. Requests are allowed or denied in part based on the identity of the requester.

For example, the right to create buckets is reserved for registered developers and by default the right to create objects in a bucket is reserved for the owner of the bucket in question.

As a developer, you'll be making requests that invoke these privileges, so you'll need to prove your identity to the system by authenticating your requests. This section shows you how. To authenticate a request, you first concatenate selected elements of the request to form a string.

Informally, we call this process "signing the request," and we call the output of the HMAC algorithm the signature, because it simulates the security properties of a real signature. Finally, you add this signature as a parameter of the request by using the syntax described in this section.

When the system receives an authenticated request, it fetches the AWS secret access key that you claim to have and uses it in the same way to compute a signature for the message it received. It then compares the signature it calculated against the signature presented by the requester. If the two signatures match, the system concludes that the requester must have access to the AWS secret access key and therefore acts with the authority of the principal to whom the key was issued. If the two signatures do not match, the request is dropped and the system responds with an error message.

If you are signing your request using temporary security credentials see Making requestsyou must include the corresponding security token in your request by adding the x-amz-security-token header. You provide the session token value in the x-amz-security-token header when you send requests to Amazon S3. The name of the standard header is unfortunate because it carries authentication information, not authorization.

Under the Amazon S3 authentication scheme, the Authorization header has the following form:. For request authentication, the AWSAccessKeyId element identifies the access key ID that was used to compute the signature and, indirectly, the developer making the request. If the request signature calculated by the system matches the Signature included with the request, the requester will have demonstrated possession of the AWS secret access key. The request will then be processed under the identity, and with the authority, of the developer to whom the key was issued.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Token Authentication using the REST API

In this blog post, we'll be going over examples of both requesting an OAuth token from the Aras Innovator server as well as using that token to authenticate additional requests. One of the features of the Authentication Server is to limit what apps can request a token.

The Authentication Server keeps a list of registered apps that are able to request tokens, so external applications cannot get tokens by default. If you don't wish to do any additional configuration, you can use the default "IOMApp" client registry.

However, we recommend adding a new client registry to register your app with the server by following the steps below. Make note of the ID you give this new registry. You will need to use it in the body of your request for a token which is covered later in this blog. The first thing we'll want to do is query for the location of the OAuthServer. The result of this request should look something like below. The response to this request is significantly longer, but it should contain our token endpoint somewhere near the top.

The final request we'll use to retrieve our token will use the token endpoint URL retrieved in the previous step. Because this token will be linked to a user's credentials, we will need to pass in additional information before making our request. If you're following along with Postman, you can use the Multipart Form to specify the following pieces of information in your body. After configuring your body, you can send a POST request to the token endpoint URL with the body containing the properties defined above.

The response will contain both the OAuth token as well as how long you will have until that token expires. By default, the IOMApp token expires in seconds or 1 hour. Token authentication using this header follows the format below. Note that the word "Bearer" must come before your token in the header. If you're using Postman, there should be a way to configure authentication differently than other headers which should automatically add in this word for you.

Alternatively, depending on the programming language you're using to perform this request, there may be a special authentication class or library which will automatically add "Bearer" into the header for you as well. You can also confirm that the permission model is still in place by querying for items to which you do not have access. I'll look into this and…. I believe this could also be related to my response on the other REST blog post.

Were you able to get this request working after you switched to JSON? Since I cannot edit my comment, but had left what what supposed to be a helpful snippet here is the corrected version - taking in account the added newline which was my mistake. I'm going to start making a generic PM collection with as many placeholders as possible.
