This document covers the steps on how an external Identity Server is used to authenticate users that log in to WSO2 IoT Server using the OpenID Connect protocol. To make it easy for you to try out the scenario, the IdentityServer4 that is hosted on is used. You can follow the same steps to configure another Identity server.

Let's get started! Follow the steps given below:

Installing OpenID Authenticator Feature in IoT Server


You need to add the federated OpenID Connect authentication configurations to the WSO2 IoT Server's default Identity Provider (IdP) configurations. Follow the steps given below:

  1. Open the <IOTS_HOME>/conf/identity/identity-providers/iot_default.xml file.
  2. Add the following configuration before the <FederatedAuthenticatorConfigs> tag.

    Code Block
  3. Add the following configurations inside the <FederatedAuthenticatorConfigs> tag.


    The IdentiyServer4's hosted demo server is available at If you are using your own external Identity Server, make sure to replace with the URL of your hosted Identity Server.

    Code Block
  4. Add OpenIDConnectAuthenticator as the value for the <DefaultAuthenticatorConfig> tag.

    Code Block

    Make sure that the above configuration is in one line as shown above. If it is broken into new lines as shown below, you run into errors.

  5. Add the following configurations inside the <ClaimConfig>  tag  tag to get the role of the user that is signing in because the demo server does not return any values.

    Code Block
  6. Anchor
    Add the following configurations inside the <PermissionAndRoleConfig> tag. The new users that get created on the fly via Just In Time (JIT) provisioning is assigned the Internal/devicemgt-admin role by default.


    This allows you to map a remote role name, which is as a role that is not defined in WSO2 IoT Server, into a local role name, which is a role that is defined in WSO2 IoT Server. In the example given below, the role that is passed from IdentityServer4 to the idp claim is mapped to the Internal/devicemgt-admin role of WSO2 IoT Server. You can use this feature to map remote roles, such as mapping the Administrator into the Internal/devicemgt-admin role.

    Code Block
  7. Add the following configurations inside the <JustInTimeProvisioningConfig> tag to enable JIT provisioning.

    Code Block
    titleWhat is JIT provisioning?

    With JIT provisioning, you can create users on the fly the first time they try to log in to WSO2 IoT Server.

Configuring the Service Providers

The Jaggery applications in WSO2 IoT Server, such as the device management, app store, and app publisher consoles, are configured as service providers to enable Single Sign-On (SSO) and authentication. For more information, on accessing the different consoles available in WSO2 IoT Server, see Accessing the WSO2 IoT Server Consoles.
You need to configure the service providers to have both the basic authentication mechanism that authenticates the user based on the username and password that was entered, and to have the OpenID Connect authentication mechanism.
For this use case, only the devicemgt service provider is configured. If you want to configure the other applications, you need to add the same configurations that are given below to the other service providers in the <IOTS_HOME>/conf/identity/service-providers directory.
  1. Open the <IOTS_HOME>/conf/identity/service-providers/devicemgt.xml file file.
  2. Add the following configurations after the <StepOrder>1</StepOrder> property.

    Code Block

Extend the log-in page for OpenID Connect


  1. Start the WSO2 IoT Server's core profile.

    Code Block
    cd <IOTS_HOME>/bin
  2. Access the device management console: https://<IOTS_HOST>:<IOTS_HTTPS_PORT>/devicemgt

    • By default, <IOTS_HOST> is localhost. However, if you are using a public IP, the respective IP address or domain needs to be specified.
    • By default, <IOTS_HTTPS_PORT> is set to 9443. However, if the port offset is incremented by n, the default port value needs to be incremented by n.
  3. Click Sign in with OpenID Connect.

    You are redirected to the OpenID connect log in page.
  4. Enter bob as the username and bob as the password, and click Login. This is the default username and password for the IdentityServer4 demo site.

    Once the authentication is successful, you are redirected into to the device management console. 



When starting off the user bob did not exist in WSO2 IoT Server. Because you configured JIT provisioning for the IdP, you see that a new user is created under Users in the WSO2 IoT Server device management console. The new users name is denoted by as a string of integers, such as 88421113.

Follow the steps given below to check the role of the user that got created:

  1. Access the IoT Server managemnet management console.
  2. On the Main tab in the Management Console, click List under Users and Roles.
  3. Click Users. This link is only visible to users with the Admin role.
  4. Click View Roles next to the new user.

    The Internal/devicemgt-admin role is assigned because you configured WSO2 IoT Server to assign this role to all the JIT provisioned users in step 6 when configuring the WSO2 IoT Server IdP.
