Due to various technical limitations, the first iteration of the customer-owned domains functionality will not be available for a few more months. We will provide an update as soon as we can get a more specific ETA.
Would need to configure our own company domain too, this is a must have feature.
We are working to support SP-initiated SSO as well. However, we don’t have timing on when it would available to customers.Sébastien commented
SAML and WS-Federation Relying Party should be supported. There are tons of applications still using these protocols only.
