I'd guess that would depend on your TACACS server.  If it supports empty 
passwords, it should work.  Note that the router may still prompt for a 
password as a part of the TACACS login mechanism, but using a blank 
password there could work.

I don't know for sure if this will work, I'd have to try it out in the 
lab, but don't have a working TACACS server down there at the moment.
