SAML SSO From Partner Portal

Question

Team,

We have a Portal called "MyPortal" deployed in Azure and it is enabled with Azure ADB2C Authentication.

Now we have a requirement to allow SSO from partner portal to MyPortal.

Users will login to PartnerPortal with its own IDP. After they login, when they click on MyPortal link displayed in PartnerPortal, it should be redirected to MyPortal without asking user to login to MyPortal.

Partner Portal is entirely different Organization, different domain and different subscription. We may need to allow from any new different Partner Portal to MyPortal using SSO.

Can someone provide a solution to achieve this requirement.

Thanks,

Suresh Rajamani

Thank you for posting your query on Microsoft Q&A, from above description I could understand that you have an application on Azure AD B2C and you wants users from different tenant to able to access the application via SSO.

Since the application is registered with B2C tenant, we need to enable SSO with other tenant to B2C.

Please do correct me if this is not the case by responding in the comments section:

• You could try Set up sign-in for multi-tenant Microsoft Entra ID using custom policies in Azure Active Directory B2C
• The SSO management could be configured within the custom policy
