I am using RADIUS to forward iChain token authentication requests to our
ACE server. It has worked perfectly in the past, but no longer.
I have two iChain servers. On one, when I attempt to do a SecurID
authentication, the RADIUS server logs an "NDS Client Error (-1)" .
From the other, I see "Access Accepted", but the logon still fails.

Any thoughts?

Thanks in advance.
