Eliminate redundant Auth challenge on reverse telnet

Hi All

Situation: I have a Router that has TACACS+ Auth enabled verifying against ACS 3.3.3. This router has also has a number of Async lines that provide out-of-band access to other network devices. I allow a “security” group defined in ACS access to TTY50 controlled with a Per Group Defined NAR.

Goal: When I authenticate to the router it challenges me for my TACACS+ username and password as expected. However, when I then reverse telnet to one of the Async lines, it again challenges me for my TACACS+ username and password before I am challenged for the authentication of the device on that line. I want to eliminate this step without affecting the group that I have given access to Async Line 50.

Can this be done?
