I have a new install of VMS 2.2 and am trying to make the initial import of Pix devices. All of the Pix I am working with are using SSH with TACACS authentication. I try using my TACACS account with the import but it doesn't pull the config from the device, says it cannot talk to the Pix. I can connect to the Pix with SSH and authenticate with TACACS fine when going into it directly. If I disable SSH authentication and use the default username of pix and the local enable password in the Pix it works. What do I have mis-configured to stop this from working?
