We are having the same issues. Been working with support for weeks now and still nos resolve. We have an MX100 firewall and it randomly will not apply the group policies that we set in Meraki that integrates with active directory. I can sign into 3 machines with my username and 2 out of the 3 machines will block access to certain sites. Basically it is applying the default policy to my account on two out of three machines. Big problem when you are the Admin and cant get to resources you need. This is also a problem due to the fact that a default user that needs restricted access to certain sites now have full access at random. When looking at the MX100 you will see the IP address doesn't match up with the logged in user. I see other users getting my policy that shouldn't.  This is a HUGE security flaw that needs to be addressed and right now with it coming up top three weeks of an issue. The only TEMPORARY fix is to white-list the IP address but if it doesn't have a static IP then someone else will get a white-listed IP that shouldn't when they get a DHCP release.  Not sure if this is just me but i feel like Meraki is dragging their feet on this.   ...
