Hmm, I'd expect that would be working properly.  if you could login to
the system using the passwd (or su/sudo), then tacacs too should have
worked.  Maybe the device is not sending those characters; which would
appear in the tacacs packet debug output.

I'm having a bit of deja vu though; have you searched the archive about
this problem?
