TACACS help needed 1

[North323]

ok when we logged into our switches, it would not prompt for username, only a password. i installed tacacs ACS on a windows box (not my choice) and I am able to log into my test switch using AD creds but not able to get into enable mode. i can get to enable mode only by the local password

any ideas?

config t
aaa new-model
aaa authentication login default tacacs+ line enable
aaa authentication enable default enable line
tacacs-server host 172.16.7.4
tacacs-server attempts 5
tacacs-server key something
line vty 0 4
login authentication default
