Package backendauth (TODO) defines the backend configuration options and element slices.

MustNew same as New() but panics on error.

New creates a new authentication service to be used as a middleware or standalone.

NewOptionFactories creates a new struct and initializes the internal map for the registration of different option factories.

OptionsError helper function to be used within the backend package or other sub-packages whose functions may return an OptionFactoryFunc.

WithBasicAuth provides the basic authentication header but allows to set a custom function to compare the input data of username and password.

WithCombineTriggers setting to true forces all authentication triggers to return true.

WithDebugLog creates a new standard library based logger with debug mode enabled.

WithDefaultConfig applies the default configuration settings for a specific scope.

WithDisable disables the current service and calls the next HTTP handler.

WithErrorHandler adds a custom error handler.

WithInvalidAuth authentication will always fail.

WithLogger convenient helper function to apply a logger to the Service type.

WithMarkPartiallyApplied if set to true marks a configuration for a scope as partially applied with functional options set via source code.

WithOptionFactory applies a function which lazily loads the options from a slow backend (config.Getter) depending on the incoming scope within a request.

WithProvider sets the authentication provider function which checks if a request should be considered valid to call the next HTTP handler on err == nil or even call the next provider.

WithResourceACLs enables to define specific URL paths to be black- and/or white listed.

WithResourceRegexpACLs same as WithResourceACLs but uses the slow pre-compiled and more powerful regexes.

WithServiceErrorHandler sets the error handler on the Service object.

WithSimpleBasicAuth sets a single username/password for a scope.

WIP.

WithTrigger sets the authentication trigger function which implements a condition to check if the list of authentication providers should be called.

WithUnauthorizedHandler sets the handler which calls the interface to request data from a user after the authentication failed.

WithUnauthorizedRedirect redirects if the authorization fails.

WithValidAuth authentication will always succeed.

OptionFactories allows to register multiple OptionFactoryFunc identified by their names.

ScopedConfig contains the configuration for a specific scope.

Service implements authentication middleware and scoped based authorization.

BasicAuthFunc defines a function to validate basic auth credentials.

Option can be used as an argument in NewService to configure it with different settings.

OptionFactoryFunc a closure around a scoped configuration to figure out which options should be returned depending on the scope brought to you during a request.

ProviderFunc checks if a request is allowed to proceed.

TriggerFunc defines the condition if the ProviderFunc should be executed.
