You want to use radius or tacacs ? Make sure you have priv 15 configured in acs,
Bring users/groups in at level 15
1. Go to user or group setup in ACS
2. Drop down to "TACACS+ Settings"
3. Place a check in "Shell (Exec)"
4. Place a check in "Privilege level" and enter "15" in the adjacent field

AAA Authorization with RADIUS and RSA SecurID Authentication Manager

Hi there.
I am in the process of implementing a new RSA SecurID deployment, and unfortunately the bulk of the IOS devices here do not support native SecurID (SDI) protocol. With the older RSA SecurID deployment version, it supported TACACS running on the system, now in 8.x it does not. Myself, along with RSA Support, are having problems getting TACACS working correctly with the new RSA Deployment, so the idea turned to possibly just using RADIUS
I have setup the RADIUS server-host, and configured the AAA authentication and authorization commands as follows:
#aaa new-model
#radius-server host 1.1.1.1 timeout 10 retransmit 3 key cisco123!
#aaa authentication login default group radius enable
#aaa authorization exec default group radius local
I have also tried
#aaa authorization exec default group radius if-authenticated local
I can successfully authenticate via SSH to User Mode using my SecurID passcode -- however, when I go to enter Priv Exec mode, it wont take the SecurID passcode - I just get an "access denied"
I've ran tcpdump on the RSA Primary Instance, looking for 1645/1646 traffic, and I dont get anything
I've turned on RADIUS debugging on the IOS device, and I dont get anything either
I did see this disclaimer in a Cisco doc: "The RADIUS method does not work on a per-username basis." -- not sure if this is related to my issue?
I'm beginning to wonder if IOS/AAA cant pass authorization-exec process to RSA SecurID

I don't have a solution, but can confirm I have the same problem and am also trying to find a solution.
I see no data sent to the RSA server when using the wireless AP. With other equipment on the same ACS, I do see the attempts going to the RSA server.
The first reply doesn't seem to apply to me, since it's not sending a request from the ACS machine to the RSA machine.

AAA Authorization named authorization list

Ladies and Gents,
Your help will be greatly appreciated – I am currently studying CCNP Switch AAA configuration and I work with a tacacs+ server at work butI having difficulty getting my head around the below
Cisco.com extract below
When you create a named method list, you are defining a particular list of authorization methods for the indicated authorization type.
Once defined, method lists must be applied to specific lines or interfaces before any of the defined methods will be performed. The only exception is the default method list (which is named "default"). If the aaa authorization command for a particular authorization type is issued without a named method list specified, the default method list is automatically applied to all interfaces or lines except those that have a named method list explicitly defined. (A defined method list overrides the default method list.) If no default method list is defined, local authorization takes place by default.
My question is how do you define the Named Method List i.e. the none-default method list?
I don't mean the cisco switch config but how the list is created, is this on the tacacs+ server and the referred to in the CLI?
Any help would be much appreciated as I have read over tons of documents and I can’t see how this is created
Thanks in advance
David

Hi David,
An example of a named AAA list might look something like this:
aaa authorization exec TacExec group AAASrv local
In the example above, I've created a AAA authorization list for controlling shell exec sessions called "TacExec", which will check the remote AAA servers in the group "AAASrv" first; if the device receives no response from the remote servers, it will then atempt to validate the credentials via the local user database. Please remember that a deny response from the AAA server is not the same as no reposonse, the device will only check the local user database if an only if it recieves nothing back from the TACACS query.
Of course, before you create this method list, you need to define the TACACS servers via the "tacacs-server" command, and then add those servers to the group via the "aaa group server" command.
Below is a cut and paste from the AAA section on one of my devices:
aaa new-model
ip tacacs source-interface
tacacs-server host 10.x.x.x key 7
tacacs-server host 10.x.x.y key 7
aaa group server tacacs+ TacSrvGrp
server 10.x.x.x
server 10.x.x.y
aaa authentication login default local
aaa authentication login TacLogin group TacSrvGrp local
aaa authorization console
aaa authorization config-commands
aaa authorization exec default local
aaa authorization exec TacAuth group TacSrvGrp local
aaa authorization commands 0 default local
aaa authorization commands 0 TacCommands0 group TacSrvGrp local
aaa authorization commands 1 default local
aaa authorization commands 1 TacCommands1 group TacSrvGrp local
aaa authorization commands 15 default local
aaa authorization commands 15 TacCommands15 group TacSrvGrp local
aaa accounting exec default start-stop group TacSrvGrp
aaa accounting commands 15 default start-stop group TacSrvGrp
aaa session-id common
Notice that for the various authentication and authorization parameters, there is a named method list as well as a default method list. As per Cisco's documentation, a aaa method list called default (that you explicitly define) will apply to all input methods (con, aux, vty, etc) unless you set a named method list on the particular input line (see below):
line con 0
exec-timeout 5 0
line aux 0
exec-timeout 5 0
line vty 0 4
exec-timeout 15 0
authorization commands 0 TacCommands0
authorization commands 1 TacCommands1
authorization commands 15 TacCommands15
authorization exec TacAuth
login authentication TacLogin
transport input ssh
For the console and aux inputs, I only ever want to use local credentials for AAA purposes (ie: If I have to connect on an out-of-band interface, something is potentially wrong with the network connectivity), however for the VTY lines (SSH sessions in this instance), I always want to use the TACACS servers first, with local user credentials as a fallback mechanism.
One thing you need to be VERY mindful of when configuring your devices for AAA is the order of the commands that are entered. It is a relatively simple matter to lock yourself out from the device management if you don't pay close attention to the specific order that the commands are entered. Typically, I will first do a "show user" just to find out which VTY line that I'm connected on, and when I assign the named AAA method lists to the VTY lines, I normally leave the line that I'm on at the default (local), then I open a second session to the device, authenticate using my TACACS credentials, and complete the config on the remaining VTY line.
Keep in mind that there are some other parameters that you can define at the tacacs-server level (timeout value is a good one to look at) which you can use to enhance the AAA performance somewhat.
Hope this helps!

AAA Authorization Using Local Database

Hi Guys,
I'm planning to use AAA authorization using local database. I have read already about it, I have configured the AAA new-model command and I have setup user's already. But I'm stuck at the part where I will already give certain user access to certain commands using local database. Hope you can help on this.
FYI: I know using ACS/TACACS+/RADIUS is much more easy and powerful but my company will most likely only use local database.

For allowing limited read only access , use this example,
We need these commands on the switch
Switch(config)#do sh run | in priv
username admin privilege 15 password 0 cisco123!
username test privilege 0 password 0 cisco
privilege exec level 0 show ip interface brief
privilege exec level 0 show ip interface
privilege exec level 0 show interface
privilege exec level 0 show switch
No need for user to login to enable mode. All priv 0 commands are now there in the user mode. See below
User Access Verification

Password:

Command execution get very slow when AAA Authorization enable on ASR 1006

Without Authorization , I am able work smoothly with just click on ASR ...., But Once I enable Authorization it takes many secs to move to other command exampe ( If i hit config t or int gi1/0/1 , it take time to move to next command level) ...
These Authorization issue I am facing only on ASR and for Other Cisco Switches and Router its working fine wiith just a click.
Did any one face such issue , and how it is fix ...

I think your issue maybe related to your tacacs server. If you re-order the two servers (typically a 5 second timer before failover occurs) and see if that improves your performance:
You can try to debug the issue by referring to the command reference guide....i.e. debug tacacs...you can also try to telnet to both ip address to port 49 to see if the connection opens, in order to rule out issues where a firewall or routing to one of the tacacs servers is failing. I also noticed you have the shared secret and tacacs server defined for one of the servers, is the sam present for the other server that is in the server group?
server 10.48.128.10
server 10.72.160.10
to
server 10.72.160.10

Aaa authorization is confusing

hi...this command make me mess for many times :(. is it true aaa authorization can return acl and time for user? how aaa authorization know what user will be associated in case aaa authentication is aaa authentication login default local? for make it more complete...is aaa authorization only work with tacacs? tx a lot ;)

Hi,
If the tacacs server fails to respond, then local network authorization will be performed.
Assuming this command: aaa authorization network test tacacs local.
Keep in mind that only a limited set of functions can be controlled via the local database.

Aaa authorization console

Hi,
i have the following config :
aaa new-model
aaa authentication login NO_LOGIN none
aaa authentication login ADMINS group radius local
aaa authentication login CONSOLE group radius local
aaa authorization exec NO_AUTHOR none
aaa authorization exec ADMINS group radius local
aaa authorization exec CONSOLE group radius local
enable secret cisco
username cisco privilage 15 secret cisco
line con 0
password 7 05080F1C2243
authorization exec CONSOLE
login authentication CONSOLE
line vty 0 4
password 7 045802150C2E0C
authorization exec ADMINS
logging synchronous
login authentication ADMINS
line vty 5 15
password 7 060506324F41
authorization exec ADMINS
logging synchronous
login authentication ADMINS
When i am tryin gto login to the switch from vty line i come directly to privillage mode, but when loging to console port i come to the exec mode (privilage 1) and i cant go further to the user privillage mode . each time i have to type a password (i type the enable one) and my access is denied.
when issuing the command # aaa authorization console (using telnet from other switch)
the problem is solved.
Can someone please explain why is this happening? i think after logging in with local account (with privillage 15) from console port i should get directly to privilage mode, or am i wrong ?

aaa authorization console is a hidden command. We have to execute this command to enable authorization for console line. If you create a method list "aaa authorization exec CONSOLE group radius local" for console and try to apply it on line console 0, it will throw an error that without "aaa authorization console" all authorization commands for console is useless. You have to first enable authorization for console with the help of aaa authorization console.

FWSM - AAA Authorization

How to map this command from IOS to FWSM ?
I want user when login and authenticated, it right way go direct to exec mode. No problem at IOS but , not sure how to configure it on FWSM or PIX Firewall.
aaa authentication enable default enable none
aaa authorization exec default group tacacs+ if-authenticated

The configuration on the FWSM for AAA will be same as would be on a normal PIX. The documents have more details about the same.

AAA authorization and accounting

Hello everyone.
I am given a project to implement AAA on routers and switches in our environment. Can some one please help me out in understanding the difference between,
1) aaa authorization exec and aaa authorization command option.
2) aaa accounting exec and aaa accounting command option.
Many thanks.
Sent from Cisco Technical Support Android App

Hello,
1) aaa authorization exec and aaa authorization command option.
The first one authorizes if the user has the right privilege level to enter to one of the IOS priviliege levels (0,1,15) you can customize this.
The second one authorizes the different commands a user can type and send to the device
2) aaa accounting exec and aaa accounting command option.
The first one again accounts when a users enters a specific user-level (Privileged level 15 or Exec user-level 1)
Second one sends an accounting message per each command send to the box
Check my blog at http:laguiadelnetworking.com for further information.

Aaa authorization with Tacacs+

Hello All,
I am trying to figure out how aaa authorization with tacacs+ works.
I am totally comfortable with aaa authentication..But am not able to understand how it works...How diff priv levels are assigned to diff users?..
I am totally freaked out...

The device side side setup is pretty simple. You just use the aaa authorization command set. A good bit of the setup is on the ACS server end.
Cisco has a pretty thorough configuration example posted here.

AAA Authorization on PIX

I have set up authentication and Authorization on the PIX. Authentication works but Authorization fails. I try to debug but nothing shows up (on PIX or ACS), but it does if I debug Authentication

Make sure you have enable authentication ,
aaa authentication ssh console TACACS LOCAL
aaa authentication telnet console TACACS LOCAL
aaa authentication enable console TACACS LOCAL
aaa authorization command TACACS LOCAL
Incase it does not work pls get aaa config

Cisco 4948 issue 122-46.SG on AAA authorization

I have faced a problem regarding AAA line:
aaa authorization exec default group tacacs+ local
if i add this line in my cisco 4948 switch running on 122-46.SG.. The next time i telnet to the switch i get an automatic restart of the switch and all configs are lost.
IOS used:
cat4500-ipbase-mz.122-46.SG.bin
WS-C4948-10GE

I think it is better to move the thread to the swtiching part. They may help you better.

Aaa authorization config-commands

Hello,
Can anybody explain what is the purpose of this command. I studied the documentation (command reference) but unable to clearly understand the purpose of this command.
Thanks in advance,
Regards,
Mo

This was the best desciption of this command I could find on cisco's site. It sounds to me like if you use the no form of this command you will not be able to use any configuration commands.
Cisco:
Usage Guidelines
If the aaa authorization commands level method command is enabled, all commands, including configuration commands, are authorized by authentication, authorization, and accounting (AAA) using the method specified. Because there are configuration commands that are identical to some EXEC-level commands, there can be some confusion in the authorization process. Using the no aaa authorization config-commands command stops the network access server from attempting configuration command authorization.
After the no form of this command has been entered, AAA authorization of configuration commands is completely disabled. Care should be taken before entering the no form of this command because it potentially reduces the amount of administrative control on configuration commands.
Use the aaa authorization config-commands command if, after using the no form of this command, you need to reestablish the default set by the aaa authorization commands level method command.
Note You will get the same result if you (1) do not configure this command, or (2) configure no aaa authorization config-commands.
The following example specifies that TACACS+ authorization is run for level 15 commands and that AAA authorization of configuration commands is disabled:
aaa new-model
aaa authorization command 15 group tacacs+ none
no aaa authorization config-commands

AAA Authorization

Im trying to configure AAA authentication using username xxxxx privililege 15 password xxxx. I would like it so users with privilege level 15 go straight to enable mode and users with prvilege level 1 will go straight to router> read only. Currently the conly commands I have typed in are username
xxx privilege 15 password xxxx
AAA new-model
Do I need to configure anything else. I tried to put privilege level under int vty but then all users go to privilege mode. I only want to use AAA I do not want to have3 to setup a teacs or radius server. Thanks in advance.

To use privilege levels you need to define authorization as well as authentication. The following should do the trick for you:
username glenn privilege 15 password 0 cisco
username fred privilege 1 password 0 cisco
aaa new-model
aaa authentication login default local
aaa authorization exec default local
Now if I login:
> telnet 10.66.79.100
User Access Verification
Username: glenn
Password:
Router#sho priv
Current privilege level is 15
Router#q
>
>
> telnet 10.66.79.100
User Access Verification
Username: fred
Password:
Router>sho priv
Current privilege level is 1
Router>q

AAA Authorization help

I have configured authentication for the outside users to connect to my servers using the following sample acl
access-list 110 permit tcp any host 10.10.10.3 eq http
access-list 110 permit tcp any host 10.10.10.4 eq http
access-list 110 permit tcp any host 10.10.10.5 eq http
aaa authentication match 110 outside TACACS+
Now for authorizing them do i have to create another set of acls or can i just use the existing acls and write
aaa authorization match 110 outside TACACS+
Is there anything else i should do on the AAA-Server for authorization?
Thanks
Jason

Hi Jason,
You can use the same ACL for authorization. You will not have to do anything on ACS unless you need to push ACLs for the user.

Vivek
