Hi, currently my company has bought a WLan Controller for users to login to wireless internet by their LDAP account provided from our company.
The WLAN controller is 4IPNet WHG515
1.User can use their device to connect to wireless internet( no password required)
2.User can only access to websites on white list, without or before login.(webpage login)
Ex: my company website, web mail etc…
so, WAN is restricted, until they login.
Certificate info looks normal on my own computer which have normal access to Wan.
I have added letsencrypt.org and identrust.com to white list, (wildcard apply to before and after domain name)
And Clients who access to login page still face a problem that it can no grab certificate information
and it shows that this page is not secure.
Is there any other domain or IP address that im missing out and it should be added to white list in order for the certificate to grab information from other certificate servers?
