| *`identityProviders`* __xref:{anchor_prefix}-go-pinniped-dev-generated-1-22-apis-supervisor-config-v1alpha1-federationdomainidentityprovider[$$FederationDomainIdentityProvider$$] array__ | 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.

| Field | Description
| *`constants`* __xref:{anchor_prefix}-go-pinniped-dev-generated-1-22-apis-supervisor-config-v1alpha1-federationdomaintransformsconstant[$$FederationDomainTransformsConstant$$] array__ | Constants defines constant variables and their values which will be made available to the transform expressions.
| *`expressions`* __xref:{anchor_prefix}-go-pinniped-dev-generated-1-22-apis-supervisor-config-v1alpha1-federationdomaintransformsexpression[$$FederationDomainTransformsExpression$$] array__ | 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.
| *`examples`* __xref:{anchor_prefix}-go-pinniped-dev-generated-1-22-apis-supervisor-config-v1alpha1-federationdomaintransformsexample[$$FederationDomainTransformsExample$$] array__ | 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.

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. \n 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."

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.

| Field | Description
| *`constants`* __xref:{anchor_prefix}-go-pinniped-dev-generated-1-25-apis-supervisor-config-v1alpha1-federationdomaintransformsconstant[$$FederationDomainTransformsConstant$$] array__ | Constants defines constant variables and their values which will be made available to the transform expressions.
| *`expressions`* __xref:{anchor_prefix}-go-pinniped-dev-generated-1-25-apis-supervisor-config-v1alpha1-federationdomaintransformsexpression[$$FederationDomainTransformsExpression$$] array__ | 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.
| *`examples`* __xref:{anchor_prefix}-go-pinniped-dev-generated-1-25-apis-supervisor-config-v1alpha1-federationdomaintransformsexample[$$FederationDomainTransformsExample$$] array__ | 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.

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.
