properties:
identityProviders:
description: |-
IdentityProviders is the list of identity providers available for use by this FederationDomain.
An identity provider CR (e.g. OIDCIdentityProvider or LDAPIdentityProvider) describes how to connect to a server,
how to talk in a specific protocol for authentication, and how to use the schema of that server/protocol to
extract a normalized user identity. Normalized user identities include a username and a list of group names.
In contrast, IdentityProviders describes how to use that normalized identity in those Kubernetes clusters which
belong to this FederationDomain. Each entry in IdentityProviders can be configured with arbitrary transformations
on that normalized identity. For example, a transformation can add a prefix to all usernames to help avoid
accidental conflicts when multiple identity providers have different users with the same username (e.g.
"idp1:ryan" versus "idp2:ryan"). Each entry in IdentityProviders can also implement arbitrary authentication
rejection policies. Even though a user was able to authenticate with the identity provider, a policy can disallow
the authentication to the Kubernetes clusters that belong to this FederationDomain. For example, a policy could
disallow the authentication unless the user belongs to a specific group in the identity provider.
For backwards compatibility with versions of Pinniped which predate support for multiple identity providers,
an empty IdentityProviders list will cause the FederationDomain to use all available identity providers which
exist in the same namespace, but also to reject all authentication requests when there is more than one identity
provider currently defined. In this backwards compatibility mode, the name of the identity provider resource
(e.g. the Name of an OIDCIdentityProvider resource) will be used as the name of the identity provider in this
FederationDomain. This mode is provided to make upgrading from older versions easier. However, instead of
relying on this backwards compatibility mode, please consider this mode to be deprecated and please instead
explicitly list the identity provider using this IdentityProviders field.

examples:
description: |-
Examples can optionally be used to ensure that the sequence of transformation expressions are working as
expected. Examples define sample input identities which are then run through the expression list, and the
results are compared to the expected results. If any example in this list fails, then this
identity provider will not be available for use within this FederationDomain, and the error(s) will be
added to the FederationDomain status. This can be used to help guard against programming mistakes in the
expressions, and also act as living documentation for other administrators to better understand the expressions.

message:

Message is the expected error message of the transforms. When Rejected is true, then Message is the expected

then Message will be treated as the default error message for authentication attempts which are rejected by a
policy. When Rejected is false, then Message is the expected error message for some other non-policy
transformation error, such as a runtime error. When Rejected is false, there is no default expected Message.
type: string
rejected:
description: |-
Rejected is a boolean that indicates whether authentication is expected to be rejected by a policy expression
after the transformations have been applied. True means that it is expected that the authentication would be
rejected. The default value of false means that it is expected that the authentication would not be rejected
by any policy expression.

expressions:
description: |-
Expressions are an optional list of transforms and policies to be executed in the order given during every
authentication attempt, including during every session refresh.
Each is a CEL expression. It may use the basic CEL language as defined in
https://github.com/google/cel-spec/blob/master/doc/langdef.md plus the CEL string extensions defined in
https://github.com/google/cel-go/tree/master/ext#strings.
The username and groups extracted from the identity provider, and the constants defined in this CR, are
available as variables in all expressions. The username is provided via a variable called `username` and
the list of group names is provided via a variable called `groups` (which may be an empty list).
Each user-provided constants is provided via a variable named `strConst.varName` for string constants
and `strListConst.varName` for string list constants.
The only allowed types for expressions are currently policy/v1, username/v1, and groups/v1.
Each policy/v1 must return a boolean, and when it returns false, no more expressions from the list are evaluated
and the authentication attempt is rejected.
Transformations of type policy/v1 do not return usernames or group names, and therefore cannot change the
username or group names.
Each username/v1 transform must return the new username (a string), which can be the same as the old username.
Transformations of type username/v1 do not return group names, and therefore cannot change the group names.
Each groups/v1 transform must return the new groups list (list of strings), which can be the same as the old
groups list.
Transformations of type groups/v1 do not return usernames, and therefore cannot change the usernames.
After each expression, the new (potentially changed) username or groups get passed to the following expression.
Any compilation or static type-checking failure of any expression will cause an error status on the FederationDomain.
During an authentication attempt, any unexpected runtime evaluation errors (e.g. division by zero) cause the
authentication attempt to fail. When all expressions evaluate successfully, then the (potentially changed) username
and group names have been decided for that authentication attempt.

secretName:

SecretName is an optional name of a Secret in the same namespace, of type `kubernetes.io/tls`, which contains
the TLS serving certificate for the HTTPS endpoints served by this FederationDomain. When provided, the TLS Secret
named here must contain keys named `tls.crt` and `tls.key` that contain the certificate and private key to use
for TLS.
Server Name Indication (SNI) is an extension to the Transport Layer Security (TLS) supported by all major browsers.
SecretName is required if you would like to use different TLS certificates for issuers of different hostnames.
SNI requests do not include port numbers, so all issuers with the same DNS hostname must use the same
SecretName value even if they have different port numbers.
SecretName is not required when you would like to use only the HTTP endpoints (e.g. when the HTTP listener is
configured to listen on loopback interfaces or UNIX domain sockets for traffic from a service mesh sidecar).
It is also not required when you would like all requests to this OIDC Provider's HTTPS endpoints to
use the default TLS certificate, which is configured elsewhere.
When your Issuer URL's host is an IP address, then this field is ignored. SNI does not work for IP addresses.
