Implementing OpenID Connect (OIDC)

When OIDC is enabled or in test mode, users are presented with a sign-in screen that only displays an email field.

Figure 1: Staff site view

Figure 2: Public site view

When they enter their email, they are redirected to the OIDC provider to enter their remaining credentials. The external directory verifies their credentials and redirects the user back to iMIS after they have successfully logged in. If the user did not have an iMIS account, one is created for them at this time and the following information is added to iMIS from the OIDC provider:

• First and Last name
• Email address: The email address is also used as their username

Figure 3: System administrator view

System administrators have the option to use their iMIS credentials or OIDC credentials. Staff and public users only have the option to their OIDC credentials.

Review the following before you begin configuring OIDC:

• To avoid disruption for staff users, it is recommended to test and configure OIDC during non-business hours.
• Depending on how OIDC is configured, the Email address field in the Synchronize primary phone numbers and email section (Settings > Contacts > System options) is overruled by the email address used by the external directory:
  • Staff users only: OIDC syncs staff user email addresses from the external directory, while public user email addresses continue to sync according to the Email address setting.
  • Staff and public users: All email addresses synchronization comes from the external directory.
• OIDC cannot be used with multi-factor authentication (MFA). If OIDC is enabled or in test mode, then MFA is automatically disabled. Similarly, if MFA is enabled, then OIDC is disabled.

Note: MFA is still recommended for the external directory sign in.

• When OIDC is enabled, staff users who are not system administrators are unable to access the iMIS Staff site through the API, which means they cannot request a new token from the token endpoint using the password grant_type. System administrators can still receive their token with a password. External SSO applications can still receive staff users’ token and use the refresh_token grant type.
• Before you begin, ensure all iMIS staff users are properly configured with a first and last name in either Entra ID or Okta. After OIDC is enabled, the staff users’ first and last names and email in iMIS are synchronized with the external directory; therefore, the users’ first and last names and email can no longer be updated in iMIS.
• OIDC for public user authentication supports only a single external provider in an all-or-nothing configuration. This means all public users must be authenticated through the chosen external directory, with no option for mixed authentication methods.

Review and complete the following sections before configuring the iMIS OIDC settings.

Ensure each staff user has a first and last name in Entra ID

Each user must have a first and last name in the external directory. This is the name that is synchronized with iMIS after OIDC is enabled. The user’s first and last names cannot be updated in iMIS after OIDC is enabled, since the name is being pulled from the external directory.

Before you begin, ensure all iMIS staff users are properly configured with a first and last name in the Entra ID.

7. Select id_token from the Response type drop-down.
8. From the Scopes field, enter the following:
   • openid
   • profile
   • email
9. Click Preview Token.

iMIS prerequisites

Before configuring OIDC, confirm the following are configured in iMIS:

• Ensure the OpenID Connect license appears in Settings > About iMIS. If you do not see the license, contact ASI Technical Support.
• OIDC does not update the staff user’s iMIS username and instead uses their email address. Verify staff users have their OIDC email address on their iMIS account page.

Configuring OIDC

You must be a system administrator to configure OIDC.

Entra ID

(new image)

Okta

Do the following to configure iMIS with your external directory:

1. Go to Settings > Contacts > Open ID Connect.
2. Select one of the following OIDC authentication options:

   Note: To avoid disruption for staff users, it is recommended to test and configure OIDC during non-business hours.

   • Disabled – Select to disable OIDC. When selected, users can only log in with their iMIS credentials.
   • Test mode – Select when testing the connection with iMIS and the external directory. When selected, staff users can sign in with their iMIS or external directory credentials.
   • Enabled – Select to enable the external directory. When selected, the external directory is the only sign in option for staff users. System administrators can still sign in with their iMIS credentials.
3. Enter the Authentication service:

   Note: Some of the Authentication service values are in your organization’s external directory portal (such as, Azure portal). You must have access to the specific tenant to find these values. See the Microsoft Documentation for more information.

   1. Type – Select your directory provider. Currently, Entra ID and Okta are supported.
   2. Name – Enter the Name of your external directory; for example, ASI OpenID Connect. This can be any name, as it currently does not appear anywhere.
   3. Client ID – The Client ID assigned to your app. For Entra ID users, this is the Application (client) ID. For Okta users, this is the Client ID.
   4. (Okta only) Client Secret - The Client Secret is located on the General tab of your Application.
   5. (Okta only) Well-Known URL - This is the Metadata URI located on the Settings tab of the default Authorization Server. See below for more information.
   6. (Entra ID only) Tenant - The Tenant assigned to your app is the Directory (tenant) ID.
   7. Authority URL:

      • Entra ID - Enter https://login.microsoftonline.com/<tenant>/, where <tenant> is the string entered in the Tenant field.

      There are common authority URLs defined in the Microsoft Documentation.

      Example: https://login.microsoftonline.com/ae2d240f-abc1-def2-ghi3-jklmnop45678

      • Okta - The Authority URL is the Okta URL that is used for authentication with iMIS:
        1. From the Okta developer portal, go to Security > API.
        2. From the Authorization Servers tab, click the default link. This is the server generated by Okta.
        3. From the Settings tab, locate the Metadata URI and Issuer fields. The Metadata URI is the Well-Known URL field in your iMIS OIDC configuration. The Issuer (or Okta URL) is your Authority URL in your iMIS OIDC configuration.
   8. External Claim ID - When set, this custom claim enables you to assign a unique identifier to users that is not their email address. The value entered in this field must correspond to your active directory configuration. See Configure optional claims for Entra ID, and Add custom claims for Okta.
   9. Redirect login URL – The redirect URL of your app, where authentication responses can be sent and received by your app. A redirect URI is the location where the authorization server sends the user once the app has been successfully authorized and granted an authorization code or access token. For many users, this will be their iMIS URL, such as https://example.imiscloud.com/. This URL must match exactly with the Redirect URI defined in your external directory. More information about the Redirect URI is in the Microsoft Documentation.
   10. Set login hint – When enabled, the staff user only needs to enter their email address in iMIS. When they are redirected to the OIDC provider, their email address is automatically populated in the OIDC authentication interface.
4. In the User autentication section, define the claim information that is used to verify that a user authenticated by the identify provider is a staff user:
   • Require OIDC for - Select Staff Only or Staff & Public Users to restrict OIDC logins for specific users. If Staff & Public Users is selected, all users are authenticated by the external provider, with no exception.

   Note: When Staff Only is enabled, OIDC syncs staff user email addresses from the external directory, while public user email addresses continue to sync according to the Email address setting. If Staff & Public Users is enabled, all synchronization comes from the external directory.

   • Entra ID:
     • Claim type - The URI (Claim type) for the associated Claim value. The instructions above use the app Role as the Claim value, so the Claim type URI is the following: http://schemas.microsoft.com/ws/2008/06/identity/claims/role

     Important! If you are not using the app Role to verify the user's authentication, you must review the Microsoft list of claim types to determine which claim type URI is right for you. It is important that the URI is copied exactly as it appears in the Microsoft list of claim types. The URI must begin with http and cannot begin with https.

     • Claim value - Enter the Value of the app role you created. The instructions above suggested the following value: iMIS_OIDC_Access

     Note: See the Microsoft Documentation for more information about custom claims.

   • Okta: 
     • Claim type - This field is not required for Okta configuration but is required to have a value. Enter http://schemas.microsoft.com/ws/2008/06/identity/claims/role to populate the field. For more information on Okta claims, see the Okta documentation.
     • Claim value - Enter SysAdmin.
5. Under the Forgot username or password email section, enter the Email body that is sent to a staff user when they use the Forgot my username or Forgot my password forms in a website other than the Staff site. It is important that the Email body indicates that the staff user must sign in to iMIS using the Staff site with a link to your organization’s Staff site.
6. Click Save. If the OIDC authentication is set to Enabled, a confirmation displays after clicking Save. You must confirm that signing in with a standard iMIS username and password will no longer work for the specified user types, except for system administrators.

Any activity through the OIDC service is logged and only available to system administrators. The logs contain detailed information about requests that are sent or received through the service or any error messages.

Do the following to review the OIDC logs:

1. Go to Settings > Contacts > Open ID Connect.
2. Click the Logs tab.
3. Use the Level drop-down to filter the logs based on the type of message.
4. Use the Message contains field to filter the logs based on a part of a message.
5. Use the Occurred between fields to filter the logs based on the date the log occurred.
6. Click Find.

Use the following troubleshooting tips while configuring OIDC.

Cannot log into the Staff site

If you've enabled OpenID Connect and can no longer log into the Staff site, do the following:

1. Navigate to a RiSE website that is not the Staff site, such as a public member site.
2. Log into that site.
3. Once logged in, update the URL to the staff site URL.

You should now have access to the Staff site.
