Inwebo Authentication

You can secure your CAS server with a second factor provided by Inwebo.

A complete documentation of this integration can be found on the Inwebo documentation website.

Apart from this CAS integration, notice that this identity provider can provide more general authentication solutions.

Support is enabled by including the following module in the overlay:

The integration adds support for both push mobile/desktop and browser authentications (Virtual Authenticator or mAccess WEB).

Configuration

The following settings and properties are available from the CAS configuration catalog:

The configuration settings listed below are tagged as Required in the CAS configuration metadata. This flag indicates that the presence of the setting may be needed to activate or affect the behavior of the CAS feature and generally should be reviewed, possibly owned and adjusted. If the setting is assigned a default value, you do not need to strictly put the setting in your copy of the configuration, but should review it nonetheless to make sure it matches your deployment expectations.

  • cas.authn.mfa.inwebo.bypass.groovy.location=
  • The location of the resource. Resources can be URLS, or files found either on the classpath or outside somewhere in the file system.

    In the event the configured resource is a Groovy script, specially if the script set to reload on changes, you may need to adjust the total number of inotify instances. On Linux, you may need to add the following line to /etc/sysctl.conf: fs.inotify.max_user_instances = 256.

    You can check the current value via cat /proc/sys/fs/inotify/max_user_instances.

    How can I configure this property?

    The configuration settings listed below are tagged as Optional in the CAS configuration metadata. This flag indicates that the presence of the setting is not immediately necessary in the end-user CAS configuration, because a default value is assigned or the activation of the feature is not conditionally controlled by the setting value. You should only include this field in your configuration if you need to modify the default value.

  • cas.authn.mfa.inwebo.bypass.authentication-attribute-name=
  • Skip multifactor authentication based on designated authentication attribute names.

    org.apereo.cas.configuration.model.support.mfa.MultifactorAuthenticationProviderBypassProperties.

    How can I configure this property?

  • cas.authn.mfa.inwebo.bypass.authentication-method-name=

  • The browser authenticator to use (or none). Available values are as follows:

    • NONE: No browser authentication.

    org.apereo.cas.configuration.model.support.mfa.InweboMultifactorAuthenticationProperties.

    How can I configure this property?

  • cas.authn.mfa.inwebo.failure-mode=CLOSED
  • The failure mode policy for this MFA provider. The authentication policy by default supports fail-closed mode, which means that if you attempt to exercise a particular provider available to CAS and the provider cannot be reached, authentication will be stopped and an error will be displayed. You can of course change this behavior so that authentication proceeds without exercising the provider functionality, if that provider cannot respond. Each defined multifactor authentication provider can set its own failure mode policy. Failure modes set at this location will override the global failure mode, but defer to any failure mode set by the registered service. Available values are as follows:

    • OPEN: Disallow MFA, proceed with authentication but don't communicate MFA to the RP.
    • CLOSED: Disallow MFA, block with authentication.
    • PHANTOM: Disallow MFA, proceed with authentication and communicate MFA to the RP.
    • NONE: Do not check for failure at all.
    • UNDEFINED: The default one indicating that no failure mode is set at all.

    How can I configure this property?

  • cas.authn.mfa.inwebo.id=
  • The identifier for the multifactor provider. In most cases, this need not be configured explicitly, unless multiple instances of the same provider type are configured in CAS.
