I have an ASA5505 running 8.2(5). It is configured with
aaa authentication telnet console xxxxxx LOCAL
and I am able to use my username and password to telnet in, but I then have to use the local enable password to get to privilege exec mode.
I tried configuring aaa authentication enable console xxxxxx LOCAL so that when I try to access privilege exec mode,I would be prompted for my password instead of the enable password, but it doesn't work.
I also tried removing the aaa authentication telnet console xxxxxx LOCAL and telenetted in with the local passwd.
I was prompted for a username and password when trying to get to priv exec mode, but again, the credentials did not work.
Could there be something that needs to be changed on the ACS server to make this work?
Thanks.

Hello-
What protocol are you using: Radius or TACACS+
Are you pusing any command authorization rules
Can you post a snip-it of your config
Once you authenticate, have you tried to use "login" vs "enable"
Thank you for rating!

Using TACACS+
No command authorization rules are being used
When I add the aaa authentication enable console xxxxxxxx LOCAL command,
and use login instead of enable, I get Login failed if I try to use my credentials.
However, if I use login with the locally configured username and password, it lets me in.
Here is the config (without the aaa authentication enable console command):

OK so since you are able to login with the TACACS credentials that means that you got the authentication peace done properly. Now since you are not able to get to the exec level then that means that the authorization part is not configured properly on either your ASA and/or ACS. A couple more questions:
1. What version of ACS are you using
2. Are you passing privilege level 15 profile from ACS
3. I am not that good with ASAs but I think you need to add some authorization commands to your ASA as well. Try:
aaa authorization command your_server_name/IP
aaa authorization exec authentication-server
