SAML Integration with Wiki

Greetings. We just purchased the Wiki module for evaluation for our org. We currently use Azure AD as our user and directory service. One of the requirements is to have users login using their Office 365 login (i.e. SAML via Azure AD) so that they don't need another user name as password. It would also make provisioning and account management much easier.

To add there seems to be confusion on where the Wiki product belongs and the documentation doesn't seem to match up. Further, it looks like Wiki will be folded into Zoho One (which may increase my subscription cost).

So, my question is can I accomplish this function with just the Wiki product or do I need to also purchase the Vault Standard edition? Or is there another simpler way for federated identity management?

Thanks.
