Introduction

This module is responsible for verifying the user's identity and issuing a valid JWT that can be used for system access. The implementation of this module may vary (username/password, SAML, OAuth, etc.), and it is possible for more than one Authentication module to exist in a running system. The default implementation uses a simple username and password for authentication.

Environment variables

  • LOGIN_COOKIE_SAMESITE - Configures the SameSite attribute of the login token cookies. Must be Strict, Lax or None. Defaults to Lax if not set.

Module properties

The following module parameters can be specified on the command line. See https://github.com/folio-org/raml-module-builder#command-line-options When specified, these will take precedence over the hard-coded defaults.

  • login.fail.to.warn.attempts - number of login attempts before warn (default value - 3)
  • login.fail.attempts - number of login attempts before block user account (default value - 5)
  • login.fail.timeout - after timeout in minutes, fail login attempts will be dropped (default value - 10)

Mod-configuration entries

The following configuration entries can be specified in mod-configuration. When present, these will take precedence over the hard-coded defaults and the module parameter values specified on the command line.
