H3C switches and Cisco ACS v5

[stu_rat]

Has anyone been able to successfully authenticate the admin access to Cisco ACS v5 using either TACACS or RADIUS?

Thanks.

This likely has your answer!

Thanks for the link.  I've got it working with Telnet but I have one small problem - it doesn't work unless the username also exists in the switch config.  Is this correct?  Can it not be done without the username being in the config?
