Define a Microsoft Entra technical profile in an Azure Active Directory B2C custom policy

  • Članak

Note

In Azure Active Directory B2C, custom policies are designed primarily to address complex scenarios. For most scenarios, we recommend that you use built-in user flows. If you've not done so, learn about custom policy starter pack in Get started with custom policies in Active Directory B2C.

Azure Active Directory B2C (Azure AD B2C) provides support for the Microsoft Entra user management. This article describes the specifics of a technical profile for interacting with a claims provider that supports this standardized protocol.

Protocol

The Name attribute of the Protocol element needs to be set to Proprietary. The handler attribute must contain the fully qualified name of the protocol handler assembly Web.TPEngine.Providers.AzureActiveDirectoryProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null.

Following custom policy starter pack Microsoft Entra technical profiles include the AAD-Common technical profile. The Microsoft Entra technical profiles don't specify the protocol because the protocol is configured in the AAD-Common technical profile:

  • AAD-UserReadUsingAlternativeSecurityId and AAD-UserReadUsingAlternativeSecurityId-NoError - Look up a social account in the directory.
  • AAD-UserWriteUsingAlternativeSecurityId - Create a new social account.
  • AAD-UserReadUsingEmailAddress - Look up a local account in the directory.
  • AAD-UserWriteUsingLogonEmail - Create a new local account.
  • AAD-UserWritePasswordUsingObjectId - Update a password of a local account.
  • AAD-UserWriteProfileUsingObjectId - Update a user profile of a local or social account.
  • AAD-UserReadUsingObjectId - Read a user profile of a local or social account.
  • AAD-UserWritePhoneNumberUsingObjectId - Write the MFA phone number of a local or social account

The following example shows the AAD-Common technical profile:

<TechnicalProfile Id="AAD-Common">
  <DisplayName>Azure Active Directory</DisplayName>
  <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.AzureActiveDirectoryProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />

  <CryptographicKeys>
    <Key Id="issuer_secret" StorageReferenceId="B2C_1A_TokenSigningKeyContainer" />
  </CryptographicKeys>

  <!-- We need this here to suppress the SelfAsserted provider from invoking SSO on validation profiles. -->
  <IncludeInSso>false</IncludeInSso>
  <UseTechnicalProfileForSessionManagement ReferenceId="SM-Noop" />
</TechnicalProfile>

InputClaims

The InputClaims element contains a claim, which is used to look up an account in the directory, or create a new one. There must be exactly one InputClaim element in the input claims collection for all Microsoft Entra technical profiles. You may need to map the name of the claim defined in your policy to the name defined in Microsoft Entra ID.

To read, update, or delete an existing user account, the input claim is a key that uniquely identifies the account in Microsoft Entra directory. For example, objectId, userPrincipalName, signInNames.emailAddress, signInNames.userName, or alternativeSecurityId.

To create a new user account, the input claim is a key that uniquely identifies a local or federated account. For example, local account: signInNames.emailAddress, or signInNames.userName. For a federated account: the alternativeSecurityId.

The InputClaimsTransformations element may contain a collection of input claims transformation elements that are used to modify the input claim or generate new one.

OutputClaims

The OutputClaims element contains a list of claims returned by the Microsoft Entra technical profile. You may need to map the name of the claim defined in your policy to the name defined in Microsoft Entra ID. You can also include claims that aren't returned by the Microsoft Entra ID, as long as you set the DefaultValue attribute.

The OutputClaimsTransformations element may contain a collection of OutputClaimsTransformation elements that are used to modify the output claims or generate new ones.

For example, the AAD-UserWriteUsingLogonEmail technical profile creates a local account and returns the following claims:

  • objectId, which is identifier of the new account
  • newUser, which indicates whether the user is new
  • authenticationSource, which sets authentication to localAccountAuthentication
  • userPrincipalName, which is the user principal name of the new account
  • signInNames.emailAddress, which is the account sign-in name, similar to the email input claim
<OutputClaims>
  <OutputClaim ClaimTypeReferenceId="objectId" />
  <OutputClaim ClaimTypeReferenceId="newUser" PartnerClaimType="newClaimsPrincipalCreated" />
  <OutputClaim ClaimTypeReferenceId="authenticationSource" DefaultValue="localAccountAuthentication" />
  <OutputClaim ClaimTypeReferenceId="userPrincipalName" />
  <OutputClaim ClaimTypeReferenceId="signInNames.emailAddress" />
</OutputClaims>

PersistedClaims

The PersistedClaims element contains all of the values that should be persisted by Microsoft Entra ID with possible mapping information between a claim type already defined in the ClaimsSchema section in the policy and the Microsoft Entra attribute name.

The AAD-UserWriteUsingLogonEmail technical profile, which creates new local account, persists following claims:

  <PersistedClaims>
    <!-- Required claims -->
    <PersistedClaim ClaimTypeReferenceId="email" PartnerClaimType="signInNames.emailAddress" />
    <PersistedClaim ClaimTypeReferenceId="newPassword" PartnerClaimType="password"/>
    <PersistedClaim ClaimTypeReferenceId="displayName" DefaultValue="unknown" />
    <PersistedClaim ClaimTypeReferenceId="passwordPolicies" DefaultValue="DisablePasswordExpiration" />

    <!-- Optional claims. -->
    <PersistedClaim ClaimTypeReferenceId="givenName" />
    <PersistedClaim ClaimTypeReferenceId="surname" />
  </PersistedClaims>

The name of the claim is the name of the Microsoft Entra attribute unless the PartnerClaimType attribute is specified, which contains the Microsoft Entra attribute name.

Requirements of an operation

  • There must be exactly one InputClaim element in the claims bag for all Microsoft Entra technical profiles.
  • The user profile attributes article describes the supported Azure AD B2C user profile attributes you can use in the input claims, output claims, and persisted claims.
  • If the operation is Write or DeleteClaims, then it must also appear in a PersistedClaims element.
  • The value of the userPrincipalName claim must be in the format of user@tenant.onmicrosoft.com.
  • The displayName claim is required and cannot be an empty string.

Microsoft Entra technical profile operations

Read

The Read operation reads data about a single user account. The following technical profile reads data about a user account using the user's objectId:

<TechnicalProfile Id="AAD-UserReadUsingObjectId">
  <Metadata>
    <Item Key="Operation">Read</Item>
    <Item Key="RaiseErrorIfClaimsPrincipalDoesNotExist">true</Item>
  </Metadata>
  <IncludeInSso>false</IncludeInSso>
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="objectId" Required="true" />
  </InputClaims>
  <OutputClaims>

    <!-- Required claims -->
    <OutputClaim ClaimTypeReferenceId="strongAuthenticationPhoneNumber" />

    <!-- Optional claims -->
    <OutputClaim ClaimTypeReferenceId="signInNames.emailAddress" />
    <OutputClaim ClaimTypeReferenceId="displayName" />
    <OutputClaim ClaimTypeReferenceId="otherMails" />
    <OutputClaim ClaimTypeReferenceId="givenName" />
    <OutputClaim ClaimTypeReferenceId="surname" />
  </OutputClaims>
  <IncludeTechnicalProfile ReferenceId="AAD-Common" />
</TechnicalProfile>

Write

The Write operation creates or updates a single user account. The following technical profile creates new social account:

<TechnicalProfile Id="AAD-UserWriteUsingAlternativeSecurityId">
  <Metadata>
    <Item Key="Operation">Write</Item>
    <Item Key="RaiseErrorIfClaimsPrincipalAlreadyExists">true</Item>
    <Item Key="UserMessageIfClaimsPrincipalAlreadyExists">You are already registered, please press the back button and sign in instead.</Item>
  </Metadata>
  <IncludeInSso>false</IncludeInSso>
  <InputClaimsTransformations>
    <InputClaimsTransformation ReferenceId="CreateOtherMailsFromEmail" />
  </InputClaimsTransformations>
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="AlternativeSecurityId" PartnerClaimType="alternativeSecurityId" Required="true" />
  </InputClaims>
  <PersistedClaims>
    <!-- Required claims -->
    <PersistedClaim ClaimTypeReferenceId="alternativeSecurityId" />
    <PersistedClaim ClaimTypeReferenceId="userPrincipalName" />
    <PersistedClaim ClaimTypeReferenceId="mailNickName" DefaultValue="unknown" />
    <PersistedClaim ClaimTypeReferenceId="displayName" DefaultValue="unknown" />

    <!-- Optional claims -->
    <PersistedClaim ClaimTypeReferenceId="otherMails" />
    <PersistedClaim ClaimTypeReferenceId="givenName" />
    <PersistedClaim ClaimTypeReferenceId="surname" />
  </PersistedClaims>
  <OutputClaims>
    <OutputClaim ClaimTypeReferenceId="objectId" />
    <OutputClaim ClaimTypeReferenceId="newUser" PartnerClaimType="newClaimsPrincipalCreated" />
    <OutputClaim ClaimTypeReferenceId="otherMails" />
  </OutputClaims>
  <IncludeTechnicalProfile ReferenceId="AAD-Common" />
  <UseTechnicalProfileForSessionManagement ReferenceId="SM-AAD" />
</TechnicalProfile>

DeleteClaims

The DeleteClaims operation clears the information from a provided list of claims. The following technical profile deletes claims:

<TechnicalProfile Id="AAD-DeleteClaimsUsingObjectId">
  <Metadata>
    <Item Key="Operation">DeleteClaims</Item>
  </Metadata>
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="objectId" Required="true" />
  </InputClaims>
  <PersistedClaims>
    <PersistedClaim ClaimTypeReferenceId="objectId" />
    <PersistedClaim ClaimTypeReferenceId="Verified.strongAuthenticationPhoneNumber" PartnerClaimType="strongAuthenticationPhoneNumber" />
  </PersistedClaims>
  <OutputClaims />
  <IncludeTechnicalProfile ReferenceId="AAD-Common" />
</TechnicalProfile>

DeleteClaimsPrincipal

The DeleteClaimsPrincipal operation deletes a single user account from the directory. The following technical profile deletes a user account from the directory using the user principal name:

<TechnicalProfile Id="AAD-DeleteUserUsingObjectId">
  <Metadata>
    <Item Key="Operation">DeleteClaimsPrincipal</Item>
  </Metadata>
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="objectId" Required="true" />
  </InputClaims>
  <OutputClaims/>
  <IncludeTechnicalProfile ReferenceId="AAD-Common" />
</TechnicalProfile>

The following technical profile deletes a social user account using alternativeSecurityId:

<TechnicalProfile Id="AAD-DeleteUserUsingAlternativeSecurityId">
  <Metadata>
    <Item Key="Operation">DeleteClaimsPrincipal</Item>
  </Metadata>
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="alternativeSecurityId" Required="true" />
  </InputClaims>
  <OutputClaims/>
  <IncludeTechnicalProfile ReferenceId="AAD-Common" />
</TechnicalProfile>
