Hi,
Devices:
ACS 5.4.4.46.0a
WS-C3550-48 with IOS c3550-ipbasek9-mz.122-25.SEB1.bin
When I was adding the switch above on ACS, I used 16 characters of shared secret and used it on the TACACS switch configuration as the key. Tried to login to the switch and my TACACS account didn't work. I used the command "test aaa group tacacs+ <username> <password> legacy" and it gave me a failed message, which I don't exactly remember what it was. So I thought of making the shared secret/tacacs key from 16 to 15 characters long then I was able to login to the switch with my TACACS account.
I am just wondering if anyone had encountered this. If it's a limitation or bug due to IOS or ACS code.
Thank you!
