Do you know, how to setting authenticaton email server? I mean, I have a SSID then user only connect to SSID with using email company. So if someone doesnt have email company, they can not connect to SSID.
The zone director does not use email as an authentication database. You can use LDAP, Radius, Active Directory and TACAS+.
If you use Active Directory users can use there email address as their username . You can restrict access to WLANs by roles. If all email users belong to a group that no other users are members of then you can assign the AD group to a role.
How I see this working the best way is for you to use ZeroIT on the WLAN with AD as the AAA source. Have an open WLAN for on boarding devices which has no access to any other resources.
