Overview

oidc implements the authenticator.Token interface using the OpenID Connect protocol.

config := oidc.OIDCOptions{
	IssuerURL:     "https://accounts.google.com",
	ClientID:      os.Getenv("GOOGLE_CLIENT_ID"),
	UsernameClaim: "email",
}
tokenAuthenticator, err := oidc.New(config)

Types

type OIDCAuthenticator

type OIDCAuthenticator struct {
	// contains filtered or unexported fields
}

func New

func New(opts OIDCOptions) (*OIDCAuthenticator, error)

New creates a token authenticator which validates OpenID Connect ID Tokens.

func (*OIDCAuthenticator) AuthenticateToken

func (a *OIDCAuthenticator) AuthenticateToken(value string) (user.Info, bool, error)

AuthenticateToken decodes and verifies an ID Token using the OIDC client, if the verification succeeds, then it will extract the user info from the JWT claims.

func (*OIDCAuthenticator) Close

func (a *OIDCAuthenticator) Close()

Close stops all goroutines used by the authenticator.

type OIDCOptions

type OIDCOptions struct {
	// IssuerURL is the URL the provider signs ID Tokens as. This will be the "iss"
	// field of all tokens produced by the provider and is used for configuration
	// discovery.
	//
	// The URL is usually the provider's URL without a path, for example
	// "https://accounts.google.com" or "https://login.salesforce.com".
	//
	// The provider must implement configuration discovery.
	// See: https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig
	IssuerURL string

	// ClientID the JWT must be issued for, the "sub" field. This plugin only trusts a single
	// client to ensure the plugin can be used with public providers.
	//
	// The plugin supports the "authorized party" OpenID Connect claim, which allows
	// specialized providers to issue tokens to a client for a different client.
	// See: https://openid.net/specs/openid-connect-core-1_0.html#IDToken
	ClientID string

	// Path to a PEM encoded root certificate of the provider.
	CAFile string

	// UsernameClaim is the JWT field to use as the user's username.
	UsernameClaim string

	// GroupsClaim, if specified, causes the OIDCAuthenticator to try to populate the user's
	// groups with an ID Token field. If the GrouppClaim field is present in an ID Token the value
	// must be a string or list of strings.
	GroupsClaim string
