I have a domain, let’s call it Domain.local. On this domain I have a domain controller called DC-Prime, and a read-only domain controller called RODC-Zeta.
I have 2 cisco wireless APs, using RADIUS to authenticate users to the domain. When they are pointed to Prime, they authenticate, and everything is sunshine and unicorns. When I point them to Zeta, the server reports the following from Event Viewer:
Negotiation failed. Requested EAP methods not available
I have exported the EAP settings from Prime and imported them to Zeta, but I still get the same results. I think it has to do with Zeta being a Read Only DC, but google and various searches have come up empty.
