HI ..Looking for a solution, how to authenticate Azure AD Users for 802.1X WIFI.We use ISE too. ISE can not "join" Azure AD?Whats the best practice to authenticate Azure AD Users via ISE for WIFI (without captive portal..)Thank you!!!

Simple Reason (ARGGGAAAAHH!!!) :-)Not only the AP need to access WLC, but also WLC must initiate Traffic towards Access Points.So Firewall Policies in the path blocked some traffic from WLC to Access Points.
