Configure Generic SSO

As an alternative to Kong Konnect’s native authentication, you can set up single sign-on (SSO) access to Konnect using OpenID Connect or SAML. This authentication method allows your users to log in to Kong Konnect using their IdP credentials, without needing a separate login. This topic covers configuring SSO for use with various identity providers.

If you want to configure Okta, please see the Okta configuration guide.

Prerequisites

Konnect must be added to your IdP as an application
Claims are set up in your IdP

Set up SSO in Konnect

OIDC

SAML

In Kong Konnect, click Organization, and then Auth Settings.
Click Configure provider for OIDC.
Paste the issuer URI from your IdP in the Issuer URI box.
Paste the client ID from your IdP in the Client ID box.
Paste the client secret from your IdP in the Client Secret box.
In the Organization Login Path box, enter a unique string. For example: examplepath.

Konnect uses this string to generate a custom login URL for your organization.

Requirements:
- The path must be unique across all Konnect organizations. If your desired path is already taken, you must to choose another one.
- The path can be any alphanumeric string.
- The path does not require a slash (/).
After clicking Save, close the configuration dialog and click Enable on your OIDC provider.

The Konnect SAML integration allows you to configure various identity providers. While technically any SAML-compliant provider can be used, the following have been verified:

Okta
Azure Active Directory
Oracle Identity Cloud Service
Keycloak

Log in to Kong Konnect, click Organization, and then select Auth Settings.
Click Configure provider under SAML.
Enter the Metadata URL from your IdP in the IDP Metadata URL field.
In the Login Path field, enter the unique string that matches the one in Okta. For example: examplepath.

Konnect uses this string to generate a custom login URL for your organization.

Requirements:
- The path must be unique across all Konnect organizations.
- The path can be any alphanumeric string.
- The path does not require a slash (/).
After clicking Save, configure the SP Entity ID and Login URL on your SAML IdP.

Test and apply the configuration

OIDC

SAML

Important: Keep built-in authentication enabled while you are testing IdP authentication. Only disable built-in authentication after successfully testing IdP authentication.

You can test the SSO configuration by navigating to the login URI based on the organization login path you set earlier. For example: https://cloud.konghq.com/login/examplepath, where examplepath is the unique login path string set in the steps above.

If your configuration is set up correctly, you will see the IdP sign-in page.

You can now manage your organization’s user permissions entirely from the IdP application.

Reference

Provider specific SAML configuration

The following section contains provider specific information and attribute mapping tables necessary for configuring SSO.

Azure

Oracle Cloud

KeyCloak

When adding an enterprise application, note that OIDC uses app registration.
Remove the namespace from the claim name in Azure. You can do this by checking Customize on the group claim.
Using groups maps to the Group ID by default.

Attribute mapping for Azure configuration:

Azure	Konnect
Identifier (Entity ID)	`sp_entity_id`
Reply URL (Assertion Consumer Service URL)	`callback_url`
App Federation Metadata Url	`idp_metadata_url`
`user.email`	`email`
`user.givenname`	`firstname`
`user.surname`	`lastname`
`user.groups`	`groups`
`user.principalname`	Unique user identifier

When configuring the Name ID format in Oracle Cloud, make sure to set it to transient.
You will need to manually upload the signing certificate from sp_metadata_url.
- cert.pem must use the X509Certificate value for signing.

Attribute mapping for Oracle Cloud configuration:

Oracle Cloud	Konnect
Entity ID	`sp_entity_id`
Assertion consumer URL	`callback_url`
App Federation Metadata Url	`idp_metadata_url`

You will need to manually upload the signing certificate from sp_metadata_url.
- cert.pem must use the X509Certificate value for signing.
Go to Realm Settings in Keycloak to locate your metadata endpoint. The sp_metadata_url for Konnect will be:http://<keycloak-url>/realms/konnect/protocol/saml/descriptor

Attribute mapping for KeyCloak configuration:

KeyCloak	Konnect
Client ID	`sp_entity_id`
Valid redirect URI	`callback_url`
App Federation Metadata Url	`idp_metadata_url`

Advanced OIDC settings

You can configure custom IdP-specific behaviors in the Advanced Settings of the OIDC configuration form. The following options are available:

Scopes: Specify the list of scopes Konnect requests from the IdP. By default, Konnect requests the openid, email, and profile scopes. The openid scope is required and cannot be removed.
Claim Mappings: Customize the mapping of required attributes to a different claim in the id_token Konnect receives from the IdP. By default, Konnect requires three attributes: Name, Email, and Groups. The values in these attributes are mapped as follows:
- name: Used as the Konnect account’s full_name.
- email: Used as the Konnect account’s email.
- groups: Used to map users to teams defined in the team mappings upon login.

Authentication issues with large numbers of groups

If users are assigned a very large number of groups (over 150 in most cases), the IdP may send the groups claim in a non-standard manner, causing authentication issues.

To work around this limitation in the IdP, we recommend using group filtering functions provided by the IdP for this purpose. Here are some quick reference guides for common IdPs:

You may need to contact the support team of your identity provider in order to learn how to filter groups emitted for the application.
