OAuth 2.0 Support

Overview

ThingsBoard allows you to provide Single Sign On functionality for your customers and automatically create tenants, customers or subcustomers using external user management platforms, that supports OAuth 2.0 protocol.
This guide is only for the Okta OAuth.

Scenario description

In this guide we will configure the OAuth with the Okta for the authentication. User is going to be logged into the Tenant and Tenant name is going to be equal to the users email. If Tenant does not exist in the system, the new Tenant will be created.

To map those external user infos from Auth0 platform we are going to use built-in basic mapper.

If basic mapper functionality will not fit your business needs, you can configure the custom mapper so that you are able to add an implementation that fits under your specific needs.

Login with Okta

Preparations

To apply the configurations properly, we need to obtain the clientName, clientId and clientSecret first.
For these reasons we first go for the Okta Developer Console.
First we need to create the application.

Then we need to specify platform type.
The platform type equals to Web in our case.

image

The name equals the clientName, and the Login Redirect URIs equals to the redirectUriTemplate from ours side.
The redirectUriTemplate can be found in the thingsboard.yml

    http://domain:port/login/oauth2/code/

Where under the domain, please, specify the current domain of yours and for the port please specify the port to have an HTTP access to the ThingsBoard instance of yours.

For the example of ours, we have the domain equals to the tb.tbsupport.xyz and the port 80, so that there is no need to specify the port additionally.

Then we need to confirm the settings we have applied.

To apply the configurations properly, we need to obtain the clientId and clientSecret first.
Those can be found on the page bottom.

image

Then we need to create the Authorization server.

image

The name and the audience can be set any for the Authorization server.

image

So that we have received three values which are required to be inserted for the thingsboard.yml of ours.

So that now we need to insert those for the thingsboard.yml.

We also need to acquire the list of the links for the next variables:

SECURITY_OAUTH2_DEFAULT_ACCESS_TOKEN_URI
SECURITY_OAUTH2_DEFAULT_AUTHORIZATION_URI
SECURITY_OAUTH2_DEFAULT_JWK_SET_URI

The Up to date list of those can be found on the link for the Metadata URI.

image

Clicking on those provide us with the json where we need to find the next fields.

{
    ...
	"authorization_endpoint":"https://dev-example.okta.com/oauth2/default/v1/authorize",
	"token_endpoint":"https://dev-example.okta.com/oauth2/default/v1/token",
    ...
	"jwks_uri":"https://dev-example.okta.com/oauth2/default/v1/keys",
    ...	
}

So that we can refer to the

SECURITY_OAUTH2_DEFAULT_ACCESS_TOKEN_URI=https://dev-example.okta.com/oauth2/default/v1/token
SECURITY_OAUTH2_DEFAULT_AUTHORIZATION_URI=https://dev-example.okta.com/oauth2/default/v1/authorize
SECURITY_OAUTH2_DEFAULT_JWK_SET_URI=https://dev-example.okta.com/oauth2/default/v1/keys

In the example of ours those equals:

clientName=ThingsBoard
clientId=XXXXXXXX
clientSecret=YYYYYYYY

Result

So that, the resulted thingsboard.yml equals the below one.

After all the changes being applied, please, make sure to have the ThingsBoard restart. The ThingsBoard restart can be invoked with the next command on the Linux Server:

$ sudo service thingsboard restart

After that, proceed to the User Interface of yours, to make sure there are no troubles, press the Login With Okta.

In case of the troubleshooting with those, please, contact us using the contact us form.
