Enable Single Sign On using Active Directory Federation Services (integration with Office 365)

I beleive that SSO is a must for any business as more business are now working more in the cloud, they have access to Azure AD, Google, Okta and many more platforms where in the past as a business you needed to have complex platforms to run SSO and therefore was used mainly by Large Enterprises who could support this… this is no longer the case. SSO platforms are available for all to use. Now I appreciate that companies that want to offer SSO integration in their products want to charge for it but as we are paying 7,800 gbp a year for pro already and I cannot justify 31,400 gbp a year to just turn on SSO (That is a 300% increase). I have spoken with the teams here and we would NOT use any of the other features that are in enterprise. Hubspot should really consider including this in Pro or they should make it available as an Addon. I would also expect JiT user addition and role management and from what I have read in the previous comments it appears this is not available.
