On the professional plan I know SAML is not available, however I would prefer to have Caspio as the identity provider as I have better control on Caspio over my users. Would this be a future feature that you will offer. I created a support ticket system on Caspio but it's using a lot of datapages, whereas I can get a free support ticket system, but this require users to have two logins one for caspio apps and one for the support ticket system.
