oxd OpenCart OpenID Connect Single Sign-On (SSO) Extension by Gluu#
The oxd OpenID Connect single sign-on (SSO) plugin for OpenCart enables you to use a standard OpenID Connect Provider (OP), like Google or the Gluu Server, to authenticate and enroll users for a OpenCart site.
OpenCart Demo Video#
You can watch a video demo of the OpenCart plugin installation and configuration here. In the video we use a Gluu Server as the OP.
In order to use the OpenCart module you will need to have a OpenCart site, standard OP (like Google or a Gluu Server) and an active oxd server. Some additional notes:.
This plugin is compatible with OpenCart Versions : 184.108.40.206 - 220.127.116.11
If you want to stand up your own OP server, you can deploy the free open source Gluu Server. Otherwise we recommend using Google.
You will need a valid license to start the oxd server. You can get a license and a $50 credit by signing up on the oxd website.

Unzip the downloaded plugin file in your OpenCart site root directory.

Installbutton, and wait for the process to complete and to display success message on the top of the page.
In your OpenCart admin Console, you should now see
OpenID Connect Single Sign-On (SSO) Extension by Gluu under
Edit button to complete the General configuration.
In the server settings section of the plugin configuration page you will need to enter information about your OP, your oxd server, and where you want to redirect users after logout.
A short description of each field follows:
URI of the OpenID Provider: Insert the URI of the OpenID Connect Provider here. If you are using Google as your OP, this will simply be
https://accounts.google.com. If you are using another OP it will be something like
Custom URI after logout: Provide a URL for a landing page to redirect users after logout of the OpenCart site, for instance
https://example.com/thank-you. If you don't have a preferred logout page we recommend simply entering your website homepage URL. If you leave this field blank the user will see the default logout page presented by OpenCart.
oxd port: Enter the oxd-server port, which you can find in your
If your OpenID Provider supports dynamic registration no additional steps are required.
If your OpenID Connect Provider does not support dynamic registration (like Google),
after clicking register two additional fields will be exposed where you need to enter
client_secret. Both values need to be obtained from the OP. To generate
client_secret use the redirect uri:
If you are using a Gluu server as your OpenID Provider,
you can make sure everything is configured properly by logging into to your
Gluu Server, navigate to the
OpenID Connect >
Search for your
oxd id. If it's present in the OP, everything worked.
Enrollment and Access Management#
In the enrollment and access management section of the plugin configuration page you can decide, (1), how new user registrations will be handled, and, (2), what role new users will receive upon registration.
You have three options for new user registrations:
Automatically register any user with an account in the OpenID Provider: By setting registration to automatic, any user with an account in the OP will be able to dyanmically register for an account on your OpenCart site;
Only register and allow ongoing access to users with one or more of the following roles in the OP: Using this option you can limit registration to users that have a specified role in the OP, for instance
OpenCart. Each time the user authenticates they will need to have this scope present in order to be approved for access (i.e. if you remove this scope from the users profile in the OP, the user would be denied access);
This is not configurable in all OP's. It is configurable if you are using a Gluu Server. Follow the instructions below to limit access based on an OP role.
Disable automatic registration: If you choose to disable automatic registration, you will need to manually add a user in OpenCart for each person that needs access. Make sure that when you add the user in OpenCart, you use the same email they have registered in the OP.
New User Default Role: Use this field to specify which role new users are assigned upon registration. If you have automatic registration set to disabled, you will have the opportunity to specify the users role during manual account creation.
Role Based Enrollment#
In order to implement role based enrollment, you will need to make changes in both the plugin and the Gluu Server.
Perform the following in the Plugin:
- In the Enrollment and Access Management section, choose the option:
Only register and allow ongoing...;
- Add a name for the role want to use to enforce access (e.g.
- Save the configuration.
- Navigate to the OpenID Connect Configuration tab;
- In the User Scopes section, check the box for
- Save your settings.
Perform the following in your Gluu Server:
- Navigate to your Gluu Server admin GUI ("oxTrust");
- Click the
Userstab in the left hand navigation menu;
- Find the person(s) who should have access;
- Click their user entry;
- Add the
User Permissionattribute to the person and specify the same value as in the plugin. For instance, if in the plugin you specify that enrollment should be limited to users with role =
OpenCart, then you should also have
OpenCartin the user entry. See a screenshot example;
- Update the user record.
Now only users with the role
OpenCart in the Gluu Server will be able to gain access to your OpenCart site.
OpenID Connect Configuration#
Navigate to the OpenID Connect Configuration tab to set your preferences for scopes and authentication.
Scopes are groups of user attributes that are sent from the OP to the application during login and enrollment. By default, the requested scopes are
openid. If you want more information about the users, you can request additional scopes.
To view your OP's available scopes, open a web browser and navigate to
https://<hostname>/.well-known/openid-configuration. For example, if you are using Google the the OP, you can see the available scopes in the Google's OP configuration.
If you are using a Gluu server as your OpenID Provider, you can view available scopes by navigating to the OpenID Configuration page as described above, or within oxTrust by navigating to
OpenID Connect >
In the authentication settings, you have two options:
- Bypass the local OpenCart login page and send users straight to the OP for authentication: If you would like to bypass OpenCart's default login page and send users straight to the OP, check this box (recommended). When this option is left unchecked users will see the following screen when trying to login:
- Select ACR:
acris an OpenID Connect specific value that enables applications to request a specific type of authentication from the OP, e.g. SMS based two factor authentication, or FIDO U2F tokens. If you are using Google as your OP, you will have to accept their default authentication mechanism. If you are using a Gluu Sever, you will be able to request any supported form of authentication. To view the OP's supported ACR values, navigate to your OpenID Provider configuration page,
acr_values. In the
Select acrfield you can choose your preferred authentication mechanism. If
none, users will be sent to pass the OP's default authentication mechanism.
Gluu Server Configuration#
If you are using a Gluu Server as your OP, you will need to configure Gluu to release the email claim. You can do so by following the below steps:
Log in to your Gluu Server dashboard ("oxTrust") and navigate to
Set the default scope field to
Claimsfield, click the
Add Claim, search for email, and add it.
- Now navigate to
