Question on L2TPv3 authentication

Thanks for all who responded to my question from last week regarding an L2TPv3 tunnel between two 3640s. I've got the config redone using loopback addresses. Now, I think I'm having a bit of trouble with authentication.

One of the 3640s authenticates logins using tacacs+. The other is a spare that I've added to the network on the local side and authenticates locally. Both sides say the tunnel is established, but the remote side (the tacacs+ side) seems to be stuck in a wt-sss state. The local side is in a wt-rep, but never gets a RemID from the remote side. I have a password set in the l2tp-class, the same password on both sides. How can I fix this?

Thanks!
