[cisco-voip] ios console access asking for old password

[Lelio Fulgenzi]

Interesting. I'm using hardware that others have used to connect to other hosts. And when I modify the config to bypass TACACS+ it works by letting me login with the enable password. Although, that's complaining and only allowing level 14, not 15. 

It's very weird.

It's behaving how it would if you hit Enter twice after entering your username, leaving the password field blank.  Is the console cable (and possibly a USB-to-serial adapter) you're using working fine to console into other routers?

Anyone seen anything like this? I'm preparing for ios upgrades and want to monitor via the console port. I've compared this to another router and the relevant settings are the same. Could this be something on the far end TACACS+ server causing me issues?
