200+ users using an wlan office with AD for captive portal WEB authentication login.
Sometimes a user received a login web portal failed message [reported devices android tablet/phone or windows7 laptop] while the same AD account is working and active when login on another device on the same wlan office. When using wlan guest on the same device, it works. Before this happened, login with this device at wlan office was just fine.
Checked AD account on ZD and test returns with "Success!"
Is this just a local device browser issue? or..
Using zd3k, firmware 9.7.1.0.30
