hi all,
we are using ACS version 5.3.0.40, NAME: "CSACS-1121-K9 chassis", DESCR: "CSACS-1121-K9.
we have diferents access groups of users, and we want that one of them can acess the devices in a location and can use all command without privilege

ACS Command line login..

Hi
I have a superadmin account in ACS.
with this account i can able to login GUI but can't able to login CLI mode.
what could be the problem ?

Hello Tony,
The ACS GUI Administrator accounts and CLI Administrator accounts are different. You cannot login with GUI accounts into CLI.
You need to use CLI created accounts to access the ACS command line. You should have created one when first installing the ACS 5.x.
If this was helpful please rate.

Problem - acs command authorization and web access control

Hi, I'm trying to add the control of some aironet 1310 bridges with a ACS 3.2 (tacacs+). I wanted to be able to do telnet command authorization restrictions trough shell command authorization sets and be able to give similar restrictive web access at the same time. I have it working if I permit some commands that are sent by the browser as "write memory quiet" and few other ones, but for it to work, I must give them limited users the privilege level 15 and by having the tacacs server authorizing the commands, it work for both, http and telnet. Where my problem begin is when I loose the connection with the ACS server, the user being already authenticated as level 15 user, the device become open to all commands; there is no more restriction applied by the ACS. Do anybody now a workaround.

It is already at local, that is just that the user already have a level 15 access and I used to control the commands through level settings before. So when I try it, my user that is localy level 5 is already recognized as a level 15 user from when it was authenticated through the ACS. If I could find a way to give web access to the 1310 at priv level 5 and still controlling the command set, it would be ok but as soon as I try to access a page that is not permitted other way than by the view level (i think it's level 1... or 0), I get a username password prompt with that line on the top of it:"level_15_or_view_access" and the only way I can access it is by entering a level 15 un/pass. I attached my 1310 aaa config
and here are the command set that work at level 15 to do a "shut" or "no shut" of the radio interface by the web interface:
configure
permit terminal
exit
permit Unmatched Args
interface
permit Dot11Radio0
no
permit shutdown
permit cca
ping
permit Unmatched Args
show
permit Unmatched Args
shutdown
permit Unmatched Args
telnet
permit Unmatched Args
write
permit memory quiet
Thanks for the help !

Host command privileges

Hello,
If my form does a host('cmd /c dir > d:\output.txt') I get the resulting listing on my application server but if I do a host('cmd /c net send myhost ping > d:\ouput.txt) I get an output.txt of size 0 and no message is sent. I have tried sending the message manually from the appserver and it works fine.
Are there some restrictions on executing commands through the host command (the appserver processes run with administrator privileges so that shouldn't be a problem)? If there are restrictions, what would be the best way to get around them (wrappers etc)?
Thanks in advance,
Nik

If it is a problem with privileges, you can try to use CPAU program (http://www.joeware.net/win32/) to run a command with privileges of a specified user.

Cisco ACS command authorization sets

I need help on the following please.
1. - I am using ACS as TACACS server to control IOS authorization on all our Switches, However I can not deny telnet sessions to other devices from within CatOS - does anyone know the command authorization set to deny this within ACS ????
2. Does anyone know where I can read up on command authorizations sets for ACS ??
3. What is the debug command for CatOS to see cli output ?
Many thanks
Rod

Thanks for your info. I have solved my problem -
1. I enabled tacacs administration logging using command on switch aaa authorization commands 15 default group tacacs+
This let me see what what happening everytime I entered a command on CatOS - via the logging monitor on ACS. From here i was able to see that when i was trying to telnet to a device from CatOS it was doing it on Privilage mode 1. I then entered this command aaa authorization commands 1 default group tacacs+ which solved my telnet problem.
Problem resolved.
Many thanks.

ACS command authorization - deny CatOS "set" commands

Cisco Secure ACS 4.2
I have a network support group that i just want to deny them the ability to use IOS and CatOS configuration commands.
I noticed that the Per Group Command Authorization is applicable to only IOS-based commands. I applied it to deny "configure", but permit everything else.
How do I go about setting this group up to deny set-based commands for the CatOS devices?

Hi
CatOS does TACACS+ right? Pretty sure it does. If it has a "shell/exec" service like IOS then ACS wont really care whether the command authorisation is IOS or CatOS - it doesnt have any specific command set knowledge. ie it uses string comparisons between what the device is requesting and what is permitted.
However, if the command authorisations are totally different (between IOS and catos devices) you might need to place them into separate NDGs so that you can map an IOS NDG to an IOS device command set and vice versa.
Hope that makes sense!

ACS command authorization report in conf t mode

Hi, this is probably a quick one, but I couldnt find a solution so far.
We are using command authorization via ACS and are thus able to see (in case of any issues) who has entered which commands at which time on which device. But this only works until someone enters conf t mode. After that I am not getting log entries in the ACS (Version 5). I can see all show commands and who entered the configuration mode, but nothing after that. Config snippet:
aaa new-model
aaa authentication attempts login 5
aaa authentication login default group tacacs+ local line enable
aaa authentication enable default group tacacs+ enable
aaa authorization exec default group tacacs+ local
aaa authorization commands 1 default group tacacs+ local
aaa authorization commands 15 default group tacacs+ local
aaa accounting exec default start-stop group tacacs+
aaa accounting commands 1 default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
aaa session-id common
My guess is that I allow all commands with that and thus no authorization is needed.
Any idea?
Thanks
Chris

Enabling Privilege Levels when ACS is Down

Hi,
I have a requirement to fall back to local accounts when ACS is down. These accounts will have specific privilege levels. I have two local users - adminro and adminrw.
adminro is read only and will have a privilege level of 7.
adminrw is a full access account with a priv level of 15.
I can login with adminro when ACS is down, but when I attempt to enable using "enable 7" I receive the following ouput:
PPD-ELPUF5/pri/act> en 7
Enabling to privilege levels is not allowed when configured for
AAA authentication. Use 'enable' only.
If I login using "enable", my read only account now has full configuration access which is not desireable.
My AAA configuration is as follows:
aaa authentication ssh console ADMIN LOCAL
aaa authentication enable console ADMIN LOCAL
aaa authentication http console ADMIN LOCAL
aaa authentication telnet console ADMIN LOCAL
aaa authentication serial console ADMIN LOCAL
aaa authorization command ADMIN LOCAL
aaa accounting ssh console ADMIN
aaa accounting command privilege 15 ADMIN
aaa accounting enable console ADMIN
aaa accounting serial console ADMIN
aaa accounting telnet console ADMIN
aaa authorization exec authentication-server
username adminro password <REMOVED> encrypted privilege 7
username adminrw password <REMOVED> encrypted privilege 15
enable password <REMOVED> level 7 encrypted
enable password <REMOVED> encrypted
Is there anyway to enable the user or automatically elevate the user to privilege 7 post login like you can with a router? I cannot have the adminro account to be able to run configuration commands on the device. Running ASA version 8.2(3).
Thanks!

ACS 5.1 command authorization in config mode

Hello all,
I have setup an ACS 5.1 system and a Cisco 3560 as test device. On the ACS system I have defined a user that will have limited access to Cisco CLI commands (privilege 15 through Shell Profile and limited commands through Command Sets). While this is working great for commands run under enable mode (meaning that the authorization denied the commands that I've specified in the Command Sets), it seems that it's not working under configure mode (e.g. I have denied commands like "router ospf" , "router bgp" , but the user can still apply them).
Before I've search this forum and found 2 posts:
https://supportforums.cisco.com/thread/2041611
https://supportforums.cisco.com/message/3057298
that suggest to have the AAA configured with:
aaa authorization config-commands
I already have this command and it still doesn't work. Actually my entire AAA config looks like this:
aaa new-model
aaa authentication login default group tacacs+ local
aaa authentication enable default group tacacs+ enable
aaa authorization config-commands
aaa authorization exec default group tacacs+ local
aaa authorization commands 1 default group tacacs+ local
aaa authorization commands 15 default group tacacs+ local
Did I miss something? Do you have any suggestion for me?
Thank you!
Calin

can you run a "debug aaa authorization" to see what happens?

Enable aaa accounting commands for all privilege levels?

Here is the command's syntax:
aaa accounting {auth-proxy | system | network | exec | connection | commands level} {default | list-name} {start-stop | stop-only | none} [broadcast] group groupname
The "command" accounting type must include the privilege level of the commands you are logging. How do I log ALL commands?
Take the following example:
aaa accounting commands 15 default start-stop group mygroup
If I issue this command will that mean commands the user executes that have a privilege level lower than 15 will not be logged? Or only commands that require exactly privilege level 15 will be logged?
How can I log all commands regardless of privilege level?

Hi Red,
If you customize the command privilege level using the privilege command, you can limit which commands the appliance accounts for by specifying a minimum privilege level. The security appliance does not account for commands that are below the minimum privilege level.
The default privilege level is 0. So if you don't specify any privilege level then all should be accounted for.
You can find the command detail at. This is for ASA though.

Hi Jean
Use privilge 15 instead privilege all

Question about usage of aaa accounting commands

Hi everyone,
I have the problem that Cisco routers and switches do not send some accounting command
information to ACS.
Accounting commands do not send to ACS are "show log" and "show version".
Accounting commands send to ACS are "show runn", "conf t" and "debug"
The configuration of routers and switches is the following
aaa new-model
aaa authentication login default group tacacs+ line
aaa authorization commands 15 default group tacacs+ none
aaa accounting exec default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
tacacs-server host xxx.xxx.xxx.xxx key yyyy
I think the commands do not send to ACS are privilege level 1 command and the commands
send to ACS are privilege level 15 command.
So I need to additional aaa accounting command below to get routers and switches send level 1
command to ACS, because the "15" of "aaa accounting commands 15" does not include level 1
so need to configure "aaa accounting commands 1" for level 1 commands.
aaa accounting commands 1 default start-stop group tacacs+
Is my understanding correct ?
Your information would be greatly appreciated.
Best regards,

Dynamic User Group Role for ASA 8 ACS 4 External Windows DB

1. I've successfully got a Win2003 AD user to authenticate to the ASA via an ACS but the default group settings the dynamic user becomes part of don't get transfered to the user. How do I get the user to adopt the group settings?
2. ASDM recommends nabling authentication for admin console sessions so you don't ssh into a box then have to login as the enable password which isn't logged. When I check the box for this feature I can ssh to the ASA but my password is denied ASA. How do I keep the user credentials all the way to the privilege exec mode?
3. Back in the day I could configure the ACS shell, privilege 15, custom attributes cisco-av-pair "priv-lvl-15" to get a user to jump directly to privilege exec mode. This doesn't work now. Is there a different way to do this on ACS v 4?
Thanks in advance,
Matt

Try this:
aaa authentication enable console
aaa authorization command
on ACS go to the user or group that the user is in and go to enable options and click on "Max Privilege for any AAA client" and set it to "15". Then go to the "tacacs+" section on click on "Shell(exec)" and click on "Privilege leve" and enter 15. Then go to the "Shell command authorization set" and set the default to permit any commands not listed. This will get the user into privilege mode. In ASA/Pix it requires command authorization and authentication for enable console. On IOS it requires that you use aaa authentication exec and then the aaa authorization exec/command. This will allow the user to go straight into privilege mode instead of user mode.

AAA authorization with ACS 3.2

I'm trying to configure my devices to use shell command authorization sets located on my ACS box. I want users that are members of a specific group to only be allowed to certain commands (ex. show). I'm pretty sure my ACS box is setup correctly, but my devices aren't. Here is the current config:
aaa new-model
aaa authentication login default group tacacs+ local
aaa authentication enable default group tacacs+ enable
aaa authorization exec default group tacacs+ local
aaa accounting exec default start-stop group tacacs+
I want the aaa authorization to use tacacs on my ACS box and whatever shell commands sets that are group specific when a user that is a member of that group logs in.

1) it is good to know that authentication is working and does fail over to the enable password. This helps assure that the problem that we are dealing with is not an issue of failure to communicate.
2) it is not necessary that the router mirror the groups that are configured on the server. So unless you want to specify authentication or authorization processing different from default then you do not need level1 to be mentioned on the router.
I agree that there is not a lot of clear documentation about authorization. One of the purposes of this forum is to allow people to ask questions about things that they do not yet understand and hopefully to get some helpful answers. As you get more experience and understand more then you may be able to participate in the forum and providing answers in addition to asking questions.
3) As I read your config authentication does have a backup method and authorization does not. I am a proponent of having backup methods configured. As long as the server is available you do not need them. But if they are not configured and the server is not available you can manage to lock yourself out of the router.
I can understand removing them while you concentrate on why the authorization is not working (though I would not do it that way) but I strongly suggest that you plan to put the backups in before you put anything like this into production.
4) the fact that both users log in and are already at privilege level 15 may be a clue. Look in the config under the console and under the vty ports. Look for this configuration command privilege level 15. If it is there remove it and test over again.
