I am facing a problem while configuring TACACS on Cisco ASA.
My Tacacs server is located @ remote site. & I am able to ping it.
But after configuring TACAS access. When I do the authentication test from ASDM it gives me an error : "ERROR: Authentication server not responding: unknown"
I had re-checked/reseted the configuration and key. But still it gives me the same error.
Thanks in Advance.
