Identity Provider Routing Rules

Identity Provider (IdPAn acronym for Identity Provider. It is a service that manages end user accounts analogous to user directories such as LDAP and Active Directory, and can send SAML responses to SPs to authenticate end users. Within this scenario, the IdP is Okta.) routing rules enable you to direct end usersIn Okta literature, we generally refer to "end users" as the people who have their own Okta home page (My Applications), using apps to authenticate into all of their apps. End users do not have any administrative control. When we refer to "users" we are generally referring to the individual(s) who have administrative control. to identity providers based on the user's location, device, email domainA domain is an attribute of an Okta organization. Okta uses a fully-qualified domain name, meaning it always includes the top-level domain (.com, .eu, etc.), but does not include the protocol (https)., attributes, or the appAn abbreviation of application. Essentially, it is a web-based site used to perform any number of specific tasks, and requires authentication from end users by signing in. they are attempting to access. (This feature is also known as IdP Discovery, because these routing rules allow Okta to discover which identity provider to use based on this context.) You can create a rule for each of your providers or for different combinations of user criteria. When an end user attempts to sign in, the active rules are evaluated, and the first one that the user matches is applied.

IdP routing rules are useful in the following scenarios:

End-user experience

When IdP routing rules are configured to select a provider based on the end user's domain or attributes, the end-user sees a modified sign-in screen that accepts the email and short names.

The sign-in is evaluated against the set criteria and the user is redirected to the appropriate sign-in screen for the desired identity provider.

Note: Routing rules improve the end-user sign-in experience, but they do not provide security enhancements. You need to configure user authentication policies for your IdPs independently of your routing rules.

Prerequisites

Before using this feature, you must configure:

Limitation: IdP Discovery on ChromeBooks only supports the Okta Identity Provider and third-party Identity Providers that have announced support for ChromeBook.

Configuration

To configure Identity Provider routing rules, navigate to Security > Identity Providers, and then click the Routing Rules tab. The default rule specifies Okta as the default identity provider. To add an additional provider, click Add Routing Rule.

  1. Enter a Rule Name.
  2. Indicate your routing specifications.
    • User's IP is: To specify a zone, at least one network zone must already be defined. For information on zones, see IP Zones.
    • User's device platform is: Select any combination mobile and desktop devices. Note: iOS devices may bypass your iOS routing rules. See Routing rules for macOS devices below for recommended configuration and end user settings.
    • User is accessing: To add an application or app instance, start typing the application name. A list of all matching apps appears.
  3. From the User matches menu, select which login attributes the user must match:
    • Anything includes all users.
    • Regex on login allows you to enter any valid regular expression based on the user login to use for matching. This is useful when specifying the domain or a user attribute is not sufficient for matching. For example, .*\+devtest@company.com matches logins for the domain @company.com but only if +devtest is included before the @ sign.
    • Domain list on login specifies a list of the domains to match (without the @ sign); for example, mytest.com. It is not necessary to escape any characters (which is required when using a regular expression).
    • User attributes specify an attribute name, a type of comparison, and a value to match. Note that if you choose Regex for the type of comparison, you must enter a valid regular expression for the value. For example, (Human Resources|Engineering|Marketing) for the Department attribute in your Okta user schema.
  4. In Use this identity provider, select the identity provider to use when all the criteria are met.

  5. Click Create Rule, and then indicate whether you want to activate the rule immediately.

Maintaining Routing Rules

Active rules are evaluated in the order that they are shown on the Routing Rules page. The first active rule that the user matches is applied.

 

  1. To change the priority of rules, hover over the area to the left of a rule number. Drag it into the order you want.
  2. To activate, deactivate, edit, or delete a rule, click the rule name, and then click an action button on the right. You cannot modify the default rule.

Routing rules for macOS devices

Due to a change in the way that Safari reports device user agents, Okta cannot differentiate between app requests that come from macOS devices and those that come from Safari on iPadOS devices.

To prevent iPadOS devices from bypassing iOS policies, configure a Deny/Catch-All routing rule that applies to macOS and iPadOS devices. To prevent iPadOS device users from being affected by your macOS app routing rules, inform them that they must do one of the following:

  • Option 1: All websites accessed from Safari (iPadOS 13 and higher). In iPad settings, go to Safari settings > Request Desktop Website and then turn off the All Websites setting.
  • Option 2: Per-website basis. Open Safari, tap Aa on the left side of the search field, and then tap Request Mobile Website.
  • Option 3. Access the target app through their Native App or Okta Mobile.
