Migrate identity providers to Azure AD B2C
The portal supports a configurable security system that lets our customers support multiple authentication systems. The portal includes its own local credentials in addition to federating with external identity providers using standard protocols such as OIDC, SAML, and WS-Federation. Going forward, we recommended that you use only Azure AD B2C identity provider for authentication and that you deprecate other identity providers.
Marking an identity provider as deprecate
You can configure your portal to mark other identity providers as deprecated and allow users to migrate to Azure AD B2C identity provider.
The following site settings are used to control the deprecation of identity providers:
|Authentication/Registration/LocalLoginDeprecated||A true or false value. If set to true, the local account will be marked as deprecated. The portal user will be required to migrate to a non-deprecated account. By default, it is set to false.|
|Authentication/[protocol]/[provider]/Deprecated||A true or false value. If set to true, the specific account will be marked as deprecated. The portal user will be required to migrate to a non-deprecated account. By default, it is set to false.|
When a portal user tries to sign in, and you have marked at least one identity provider as deprecated, the deprecated account is shown on the page. In the following example, a Microsoft account is marked as deprecated.
The text on the screen for legacy authentication provider can be changed by using the following content snippet:
|Account/Signin/SignInExternalDeprecatedFormHeading||Text||Sign in with a legacy account|
The deprecated identity providers are not shown when a user registers or redeems an invitation for a portal.
Migrating a deprecated identity provider to a new identity provider
If a portal user signs in with a deprecated identity provider, the account migration screen displays a message to sign in with a non-deprecated identity provider. When the user signs in with the non-deprecated identity provider, the user account is associated with the new provider.
The message on the screen for account migration can be changed using the following content snippets:
|Account/Conversion/PageCopy||HTML||You have signed in with an account that is no longer supported. To continue using this portal, you must migrate to a different account. Select the button below to sign in with a new or existing supported account.|
|Account/Conversion/SignInExternalFormHeading||Text||Sign in with a supported account.|
The portal allows multiple identities to be associated with a single contact record. When multiple providers are deprecated, a portal user must consent to the terms and conditions multiple times. Whenever a user signs in with a deprecated identity provider, the account migration process is initiated for each deprecated provider and the contact record is associated with the non-deprecated provider after account migration.
For example: The portal supports Microsoft account (MSA), Google, and Facebook as identity providers for authentication. If you mark Google and Facebook as deprecated providers, and a portal user only has Google and Facebook as identity providers for authentication, the user will receive the account migration message when they try to sign in using either of these two providers. When the user signs in using MSA, MSA is added to the user’s contact record. The user now has only MSA as the supported authentication identity provider.
When a portal user selects a new identity provider and the identity is already associated with another contact record, an error message appears. You can configure the error message using the following content snippets:
|Account/Signin/AccountConversionIdentityUsedErrorHeading||Text||Account Conversion Error|
|Account/Signin/AccountConversionIdentityUsedErrorText||HTML||This account already exists. Close your browser, restart the process, and select a different account on the Account Migration page.|
Disabling local login
You can configure a portal to disable local login by using the
Authentication/Registration/LocalLoginDeprecated site setting. If someone tries to sign in using local credentials, the account migration screen appears along with the instruction to sign in with a non-deprecated identity provider. When the account is migrated, local credentials for the user are disabled.
If you mark local login as deprecated, the user will not be able to register for a new account.
The following field is added in the portal contact record to indicate if the local login is disabled for a user:
Local Login Disabled: Indicates that the contact can no longer sign in to the portal using the local account. By default, it is set to No. This field is set to Yes if a user’s account is migrated to a non-deprecated identity provider and local login is disabled.
