You can join a federation as a controller or member depending on the assigned role in the invitation. An invitation is valid for ten days. You must request a new invitation after this period. If a new invitation is generated for the same site, only the latest invite is valid.
- Verify that the federation is healthy - there should be no red dots on the world map of the Multi-Instance Management Dashboard. A red dot indicates that SSDC Manager is unable to communicate with that member.
- The SDDC Manager certificate requires TLS Web server authentication and TLS Web client authentication extended key usage (EKU). If you are using Microsoft CA or a third-party CA, you must ensure that the Certificate Authority template is configured with both these EKUs.
- Retrieve the FQDN of your SDDC Manager.
