We have setup our access control for 3rd Party credentials (Student Google Accts). We are running into a couple of issues.
#1 - Around 5-10% of the students have issues with Google login page even loading. They see the Meraki Captive Portal that allows them to click the Google login icon and then it starts to load a new page but it stays blank. For the majority, it is fine and it loads the input box for an email address but for others it does not. Right now we still allow https traffic anyway but I would like to troubleshoot this issue. Any thoughts?
#2 - They are prompted to login way too often. At least a few times a day and Im pretty sure its not an IP issue. We were hoping it could be just once a day. Might this have something to do with the Controller disconnection behaviour?
I don't think I am able to answer the first question because, I think we have not established a problem yet and want some more detailed information to start with but yes for the frequency of the splash page, you can always go to wireless> splash page > Splash Frequency (By default it is one day) and adjust the value.
There is a setting under the access control called Simultaneous logins, you should try adjusting that value as well.
