Acs vpn authorization

I'm trying to authorize users on a vpn against MS active directory through an ACS. I can get RADIUS authentication to work, but I need to be able to limit access based on user, and so far all I'm getting is just authentication. Is there a way to map a vpn 3000 group to an ACS group?

The Cisco VPN 3000 Concentrator has the ability to lock users into a Concentrator group which overrides the group the user has configured in the Cisco VPN 3000 Client. In this way, access restrictions can be applied to various groups configured on the VPN Concentrator with the assurance that the users are locked into that group with the RADIUS server.

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.

Disconnect wi fi at vpn authorization

Hi everyone.
I have next problem:
If I connect to vpn server via wifi then authorization does not work
If I connect to vpn server via patch cord then the connection is established.
What could be the problem?
Please help me(
connection diagram:

I'm not VPN expert but lets check some things.
does the Wi-Fi provide the same LAN segment/IP Range as the cable?
is Wi-Fi working without VPN?
Is there any rule on the Server that prevents maybe Wi-Fi clients or the IP range used by Wi-Fi.
Any Client Policy that prevents that?
Br,

ACS VMS Authorization

(Also posted in network management)
We are running the latest version of ACS, VMS and Cisco Works. The problem that we are having is that we can authenticate off of the ACS server but when we try to edit anything on the VMS it states that we do not have the appropriate permissions to edit.
I have it set up for both users and the group to have System Admin rights in the ACS under the registered services. I can see in the ACS logs that the user authenticates using TACACS+ and logs into the service but then fails to get authorization to edit the settings. There is no error or failed authorization attempt in the failed attempts log on the ACS.
If I remove permissions by checking none in the user setup on the ACS in the failed attempts log it generates a:
Author failed
service=idscfg authorize-device=172.30.xxx.xxx cmd*admin_modify
Author failed
service=idscfg authorize-device=172.30.xxx.xxx cmd*deployment_view cmd*deployment_deploy cmd*deployment_approve cmd*deployment_generate
The TACACS+ Administration logs show:
reyxxxxx xxx users Login 1 idscfg
If I give them System Admin rights in the ACS I get the same TACACS+ administration log entry but NO entries in the Failed Attempts log. The VMS then say that the user does not have the appropriate permissions to edit the group. Would it not have the same Failed Attempt log entry if it was failing to get authorization from ACS?
Any advice?

The following link has more information on VMS database restoration.

ACS + Device Authorization Failure

Good Afternoon:
I hoping someone can help me out... I have an ACS configured with a group that is setup for admins. This group is mapped to an AD group. This is setup correctly. On each network device are the commands:
aaa authorization exec default group tacacs+ if-authenticated
I can create a local user and place them into the aformentioned group and the TACACs authentication and authorization work fine. However, I cannot use that same local group mapped to a AD group and a user in that group. It passes authentication but I get an authorization failure in my logs (ACS) and a authorization failed message on the device.
Any ideas?
Thanks!

ACS has extensive logging capabilities that allow an administrator to troubleshoot any issue pertaining to the ACS server itself (for example, replication) or an AAA request problem (for example, an authentication problem) from NAS.

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

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 !

ACS - ASA Authorization and Accounting

Hi
I have some questions regarding authorization and accounting on ASA via ACS server
when I enable the command "aaa authorization command " to control SSH users commands I get locked out on console then i have to configure the console , telnet , and enable to be authenticated via tacacs too , is there any way to authorize SSH via tacacs while keeping Console and telnet authenticated locally or even no authentication ?
i issued accounting command "aaa accounting command TAC" on ASA but i noticed that the ACS just logs commands in configuration mod "privilege 15 " not any show command or privilege 1 , is there any way to fix this ?
does RADIUS support SHELL authorization ?
thanks for your support

1.] Unfortunately, there currently isn't any way to exclude command authorization from the serial/ console or ssh users while having it apply to other access methods in case of ASA. Once you issue this command, it would be applicable for ALL methods like ssh,telnet,enable,http and console. This can be easily achieved in IOS (routers and switches) by creating a method list.
2.] When you configure the aaa accounting command command, each command other than show commands entered by an administrator is recorded and sent to the accounting server or servers. This is a default behaviour on ASA. IOS does send/record all show commands on ACS/Tacacs.

ACS shell authorization

IS it possible to configure shell authorization when the privelege level is set to anything less than 15
What i am doing right now is configuring a level 15 access and restricting the commands through shell sets. When i try to assign any other privelege level it doesn't seem to work.
HTH
Narayan

Narayan,
Lets say you assign a privilege level of 10 to the user on the AAA server. The user will log on to the device at level 10 but "sh ip int br" and "sh int" are level 15 commands, hence he will not be able to use them.
So what we will need to do is reduce the privilege level of the "sh ip int br" and "sh int" commands on the device itself to level 10 using "privilege" command in the global configuration mode.
After doing this, only "sh ip int br" and "sh int" commands will be available at level 10 and not other privilege 15 commands.
Now further if you want Group a to execute only "sh ip int br" and Group b to execute only "sh int" then you can apply command authorization for level 10.
Hope this helps

ASA and ACS 5 multiple VPN profiles for one user

Hi there
I have a question about ACS 5.3 and ASA VPN profile authorization. I am not sure if it is possible to allow one single user for a set of VPN profiles on ASA, let's make an example:
ACS 5.3 group hierarchy:
- VPN users global
-- VPN users A
-- VPN users B
ASA VPN profiles:
- VPN profile A
- VPN profile B
- VPN profile Z
VPN authorizations:
1. VPN users global should have access to VPN profiles A, B and Z (here we create an authorization profile with no class an no lock attributes, so the group is allowed for all VPN profiles)
2. VPN users A should have access to VPN profile A (here we create a authorization profile with class and lock attributes for profile A)
3. VPN users B should have access to VPN profiles B and Z (is this possible and how does the authorization profile have to look like?)
Thanks a lot in advance and best regards
Dominic

Hi Dominic,
first of all, let's clarify that on the ASA you have tunnel-groups (named connection profiles in ASDM) and group-policies. These often, but not always, have a one-to-one mapping.
The Tunnel-Group (TG) is either selected by the user (either from a drop down list or by entering a specifiv group-url), or automatically selected by a certificate map (i.e. based on a certain field in the user cert, the user is mapped to one TG or another). The TG mainly specifies what kind of authentication is used.
The Group-Policy (GP) by default is the one specified in the TG, but it can be overridden by e.g. Radius.
So from the ASA's standpoint itself your posibilities are rather limited: the ASA will just apply whatever group-policy you push from Radius (in IETF attribute 25 aka "Class"), and in addition it will deny access to a user if the TG he selected does not match the value of the group-lock attribute. Group-lock can only contain one TG name, so you cannot do something like "allow both B and Z".
In other words you can not achieve your goal if the Radius server has a "static" set of attributes per user.
However, as of ASA 8.4.3 the ASA now sends 2 vendor-specific attributes in the Access-Request:
vendor ID = 3076, attribute 146 is "Tunnel Group Name" (string).
vendor ID = 3076, attribute 150 is "Client Type" (integer)
0 = No Client specified 1 = Cisco VPN Client (IKEv1) 2 = AnyConnect Client SSL VPN 3 = Clientless SSL VPN 4 = Cut-Through-Proxy 5 = L2TP/IPsec SSL VPN 6 = AnyConnect Client IPsec VPN (IKEv2)
So if you can configure the Radius server to "dynamically" permit/deny access based on the TG attribute I suppose you could achieve what you want.
If/how ACS can do this, I personally don't know; I suggest you ask in the AAA forum if you need help with that part.

ACS authorization query

Hi,
I would like to know what are the configurations required in Cisco ACS for authorization.
I have done the foll configurations in the switch.
aaa authorization config-commands
aaa authorization exec default group tacacs+ local
radius-server host 10.240.252.247
radius-server key greenland.123
Thanks.
Rgds.,
Sack

Hi Narayan,
Sorry, I pasted the wrong configurations in the forum.Actual configurations in the device are as follows:
aaa authorization config-commands
aaa authorization exec default group radius local
radius-server host 10.240.252.247
radius-server key xxx
I would like to know what are the configurations required in the ACS server with respect to authorization as we are using radius.Do we need to add anything else apart from adding the client in ACS..?
Thanks.

AAA Authorization with ACS Shell-Sets

Hi all,
I am using a cisco 871 router running Version 12.4(11)T advanced IP Services.
I am having trouble getting AAA Authorization to work correctly with ACS.
I am able to set the users up on ACS fine and assign them shell and priv level 7.
I then setup a Shell Auth Set, and enter in the commands show and configure.
When I log in as a user, I get an exec with a priv level of 7 no problems, but I never seem to be able
to access global config mode by typing in conf (or configure) terminal or t.
If I type con? the only command there is connect, configure is never an option...
The only way I can get this to work is by entering the command:
privilege exec level 7 configure terminal
I thought the whole purpose of the ACS Shell Set was to provide this information to the Router?
This is most frustrating
The ACS Server is set up with a Shell Command Authorization Set named Level_7
It is assigned to the relevant groups and I even have the "Unmatched Commands" option selected to "Permit"
The "Permit Unmatched Args" is also selected.
See an excerpt of my IOS config below:
aaa new-model
aaa group server tacacs+ ACS
server 10.90.0.11
aaa authentication login default group ACS local
aaa authorization exec default group ACS
aaa authorization commands 7 default group ACS local
tacacs-server host 10.90.0.11 key cisco
privilege exec level 7 configure terminal
privilege exec level 7 configure
privilege exec level 7 show running-config
privilege exec level 7 show
Hope you can help me with this one..
P.s I have tried it with the privilege commands on the router and removed from the router and just keep getting the same results!?

Hi,
So here it is,
You are actually using two different options and trying to couple then together. What I would suggest you is either use Shell command authorization set feature or play with privilege level. Not both mixed together.
Above scenario might work, if you move commands to privilege level 6 and give user privilege level 7. It might not sure. Give it a try and share the result.
This is what I suggest the commands back to normal level.
Below provided are steps to configure shell command authorization:
Follow the following steps over the router:
!--- is the desired username
!--- is the desired password
!--- we create a local username and password
!--- in case we are not able to get authenticated via
!--- our tacacs+ server. To provide a back door.
username password privilege 15
!--- To apply aaa model over the router
aaa new-model
!--- Following command is to specify our ACS
!--- server location, where is the
!--- ip-address of the ACS server. And
!--- is the key that should be same over the ACS and the router.
tacacs-server host key
!--- To get users authentication via ACS, when they try to log-in
!--- If our router is unable to contact to ACS, then we will use
!--- our local username & password that we created above. This
!--- prevents us from locking out.
aaa authentication login default group tacacs+ local
aaa authorization exec default group tacacs+ local
aaa authorization config-commands
aaa authorization commands 0 default group tacacs+ local
aaa authorization commands 1 default group tacacs+ local
aaa authorization commands 15 default group tacacs+ local
!--- Following commands are for accounting the user's activity,
!--- when user is logged into the device.
aaa accounting exec default start-stop group tacacs+
aaa accounting system default start-stop group tacacs+
aaa accounting commands 0 default start-stop group tacacs+
aaa accounting commands 1 default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
Configuration on ACS
[1] Goto 'Shared Profile Components' -> 'Shell Command Authorization Sets' -> 'Add'
Provide any name to the set.
provide the sufficent description (if required)
(a) For Full Access administrative set.
In Unmatched Commands, select 'Permit'
(b) For Limited Access set.
In Unmatched commands, select 'Deny'.
And in the box above 'Add Command' box type in the main command, and in box below 'Permit unmatched Args'. Provide with the sub command allow.
For example: If we want user to be only able to access the following commads:
login
logout
exit
enable
disable
show
Then the configuration should be:
------------------------Permit unmatched Args--
login permit
logout permit
exit permit
enable permit
disable permit
configure permit terminal
interface permit ethernet
permit 0
show permit running-config
in above example, user will be allowed to run only above commands. If user tries to execute 'interface ethernet 1', user will get 'Command authorization failed'.
[2] Press 'Submit'.
[3] Goto the group on which we want to apply these command authorization set. Select 'Edit Settings'.

Authorization based on scheduling

I'm looking for a solution to help me schedule resources in our network lab. I want to require staff to schedule a resource, and then have ACS do authorization against whether or not a user has scheduled the resource. The peice I dont know about is the whole calendar/reservation piece.
I've seen this kind of scheduling for conference rooms in Exchange. I'm wondering if setting up a "conference room" type resource in Exchange would have users assigned to the resource for a particular time period in such a way that Cisco ACS could do authorization against the resource validating the username to validate login access for the resource. I'm not worried about forcing a logout at the end of the timeframe, the initial authorization would be sufficient.
Does anyone have the exposure to know if this approach could be made to work, or is there a better approach that I havent considered....I'm a bit new in this group. Thanks in advance.
Per

Hi Per,
What ACS are you using? what is the protocol?
you can try that with ACS 5.x
Hope that helps.
