K2 Product Compatibility, Integration and Support

How to use this matrix

Use this matrix to determine what products and versions of products are supported and compatible with various versions of K2. A check mark means that the listed product/version is supported by K2. If any product or version is not listed and not covered by the K2 Product Support and Release Strategy , it is not supported. A missing check mark means that the listed product/version is not supported with that specific version of K2.

Note:

Authentication (Identity Providers) Compatibility

This section lists which user identity providers can be used for inbound authentication with K2. For more on authentication in K2, see Authentication and Authorization in K2. K2 uses a concept called "user managers" to interact with identity providers; for more information on user managers in K2, see Introduction to User Managers in the installation and configuration guide. K2 Cloud uses OpenID Connect and can integrate with SCIM 2.0 identity providers for inbound authentication. If you have a SCIM 2.0-compliant and OpenID Connect-capable identity provider and do not see it listed in the supported identity providers below, please contact your K2 representative to have your identity provider assessed for future support.
