I was so hopeful, but didn't read the fine print. I was able to set up SSO, but it's only for my administrators' access to the Meraki Dashboard. When I last looked this up, this SSO was not tied into the Client VPNs users authentication. Seems like there are 2 or 3 different types of users for 2 or 3 different types of capabilities in Meraki. Hopefully these converge and we can use SSO for the Client VPN soon. Sorry to get your hopes up.
