Hi @chetanm,
Thanks for posting on RStudio Community! Shiny Server Pro supports LDAP/Active Directory authentication, google accounts, PAM, proxied authentication, or local accounts. Full details are here. It does not support SAML out-of-the-box, and there are no plans to add that feature.
If you're interested in learning more about RStudio Connect, I'd encourage you to check out the free 45-day evaluation, play around with the RStudio Team Quickstart, or schedule a demo with our sales team!
