SAML Configuration

You are browsing documentation for an outdated plugin version.

Configuration

This plugin is compatible with DB-less mode.

Compatible protocols

The SAML plugin is compatible with the following protocols:

grpc, grpcs, http, https

Parameters

Here's a list of all the parameters which can be used in this plugin's configuration:

• name or plugin

  string required

  The name of the plugin, in this case saml.

  • If using the Kong Admin API, Konnect API, declarative configuration, or decK files, the field is name.
  • If using the KongPlugin object in Kubernetes, the field is plugin.

• instance_name

  string

  An optional custom name to identify an instance of the plugin, for example saml_my-service.

  The instance name shows up in Kong Manager and in Konnect, so it's useful when running the same plugin in multiple contexts, for example, on multiple services. You can also use it to access a specific plugin instance via the Kong Admin API.

  An instance name must be unique within the following context:

  • Within a workspace for Kong Gateway Enterprise
  • Within a control plane or control plane group for Konnect
  • Globally for Kong Gateway (OSS)

• service.name or service.id

  string

  The name or ID of the service the plugin targets. Set one of these parameters if adding the plugin to a service through the top-level /plugins endpoint. Not required if using /services/{serviceName|Id}/plugins.

• route.name or route.id

  string

  The name or ID of the route the plugin targets. Set one of these parameters if adding the plugin to a route through the top-level /plugins endpoint. Not required if using /routes/{routeName|Id}/plugins.

  • session_secret

    string required referenceable encrypted matches: ^[0-9a-zA-Z/_+]+$ len_min: 32 len_max: 32

    The session secret. This must be a random string of 32 characters from the base64 alphabet (letters, numbers, /, _ and +). It is used as the secret key for encrypting session data as well as state information that is sent to the IdP in the authentication exchange.
