Cross Authentication

By mimizuraidah ·
I have two organization who wants to do cross authentication, because their workers works within these two organization.

For them to log in to the network, there are two ways: Via Token or Guest account.

If Token, There are using WPA/TKIP - SmartCard Authentication. If Guest, Have to use PEAP Authentication.

Also, there are two ways to do this thing, ie via Proxy method[ie In Domain A, user connected to AP, authentication will be forwarded to Domain B IAS,If the account and certificate is valid, an IP Address will be given to the user] , or Trust Domain method[ie In Domain A, User connected to AP, it will be authenticated in local IAS, asked for DC in DOmain B. If User account is valid, it will then ask for Certificate. If valid, it will pass back to the user and give an IP Address.( For Token)]. However, both ways are unsuccessful.

Both ways to login their own domain is a success, but is not successful for cross authentication.

If using Trust Domain method, the error we get are "The user account domain cannot be accessed" and "There is no domain controller available for domain B".

If using Proxy method, the error is" The RADIUS server does not respond".

It is not a problem with the firewall, because we have allowed all ports to be opened between this two.

Please advice. Many Thanks in advance.
