Dynamics CRM IFD Certificates

Scenario: Multiple Organizations exposed internally and externally (IFD) as sub-domains of the same main domain.

Example Organizations: Org1, Org2, Org3

Internal URLs:

https://CRM.domain.local/Org1

https://CRM.domain.local/Org2

https://CRM.domain.local/Org3

External URLs:

https://CRMOrg1.domain.com

https://CRMOrg2.domain.com

https://CRMOrg3.domain.com

As far as certificate requirements, we can use a single wildcard certificate. The challenge is though that SSL can not be bound to .local domain, so the internal URLs will need to share the same domain. They will become:

https://CRM.domain.com/Org1

https://CRM.domain.com/Org2

https://CRM.domain.com/Org3

You will find this kind of question a lot from on-premise clients that are now trying to integrate with a 3rd party solution (SaaS), and need to configure IFD.

Enjoy!
