http://rogierm.redbee.nl/blog Just another blog with technical stuff Mon, 09 Jan 2012 16:15:48 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 http://rogierm.redbee.nl/blog/2010/01/14/cisco-asa-and-tacacs-enable-fails/ http://rogierm.redbee.nl/blog/2010/01/14/cisco-asa-and-tacacs-enable-fails/#comments Thu, 14 Jan 2010 21:34:28 +0000 admin http://rogierm.redbee.nl/blog/?p=106 While migrating the authentication of our ASA firewalls to tacacs, we enabled ‘enable’ authentication to tacacs and tried to switch to enable mode on the console. This did not work, and caused the following message in the tacacs log file:

Wed Jan 13 17:07:42 2010 [25444]: enable query for 'username' 13 from 10.x.x.x rejected

To fix this problem the tacacs configuration for the user needs to include the enable password in the profile, as shown below:

user = username {
login = des "XXXXXXX"
member = admin
acl = mgmt_devices
service = shell {
priv-lvl = 15
}
enable = des "XXXXXXX"
}

We use the following configuration on the ASA to enable AAA to tacacs.

aaa-server tacacs protocol tacacs+
aaa-server tacacs (outside) host 1.1.1.1
key TACACSKEY
aaa-server tacacs (outside) host 2.2.2.2
key TACACSKEY
aaa authentication ssh console tacacs LOCAL
aaa authentication telnet console tacacs LOCAL
aaa authentication serial console tacacs LOCAL
aaa authentication enable console tacacs LOCAL
aaa authentication http console tacacs LOCAL
aaa authorization command tacacs LOCAL
