Looking at the options available that will provide authentication to a shared Enterprise Wireless LAN.
Hardware to be utilised by 3 divisional companies that share a WAN.
Each divisional company uses it own dedicated AD and dedicated LAN infrastructure.
Need to be able to have cross company / location wireless roaming.
Is this possible with the WiSM / 4402 / 4404 etc?
Any donations greatly received.
I think you are going to want to look at using an ACS solution that can support multiple LDAP directories.
