AAA Authentication Question

Here is the config I have on a switch:
aaa authentication login default group tacacs+ local
aaa authentication login vtylogin group tacacs+ local
aaa authentication login conlogin group tacacs+ enable none
aaa authentication enable default tacacs+ enable
Now here are my issues:
1- When I login from console my login from Tacacs works, but when I type "enable" and try to use my Active Directory password it does not work. Then I try the enable password, it does not work. However if I change the 4th Line to "aaa authentication enable default enable", I can proceed using the enable password.
2- My second issue is when I SSH into the switch, I only want it to use the tacacs server and only use local database when the tacacs is not available. However even when tacacs is available I am still able to log into it using the local user account. I am assuming that is by design? Is there a way to stop that if it is not by design?

But it won't use you local database unless your tacacs+ server is unavailable so I really don't see the problem.
If the router uses your local database to authenticate then there is a communication problem with your tacacs+ server so he is using the next method listed in your command which is local database. As I said before do a debug aaa authentication and you will see the router is attempting to communicate with the tacacs+ server and only if it times out then is he going to use an alternative method if it is listed in method list.

AAA authentication and authorization question

Hi Everyone,
I have a situation that is driving me crazy.
I am using Cisco Freeware TACACS running on RedHat
Enterprise Linux 3. I've modified the source code
so that I can assign each individual users his/her
own enable password. So far so good.
I create two groups: group_A and group_S. group_A
is for advanced users and group_S is for super
users. Users that belong to group_A can have
privilege level 15 but there are certain commands
that they can not perform such as "write mem"
or "reload". users that belong to group_S can do
EVERYTHING.
Here is my configuration on the TACACS configuration
file:
user = xyz {
member = admin
name = "User X"
login = des 6.z8oIm9UGHo
user = $xyz$ {
member = admin
name = "User X"
login = des c2bUC43cmsac.
user = abc {
member = advanced
name = "User abc"
login = cleartext "cisco123"
user = $abc$ {
member = advanced
name = "User abc"
login = cleartext "cisco123"
group = advanced {
default service = deny
cmd = show { permit .* }
cmd = copy { permit flash }
cmd = copy { permit running }
cmd = ping { permit .* }
cmd = configure { permit .* }
cmd = enable { permit .* }
cmd = disable { permit .* }
cmd = telnet { permit .* }
cmd = disconnect { permit .* }
cmd = where { permit .* }
cmd = set { permit .* }
cmd = clear { permit line }
cmd = exit { permit .* }
group = admin {
default service = permit
configuration of the router:
aaa new-model
aaa authentication login notac none
aaa authentication login VTY group tacacs+ local
aaa authentication login web local enable
aaa authentication enable default group tacacs+ enable
aaa authorization exec notac none
aaa authorization exec VTY group tacacs+ if-authenticated none

However, what I would like to do is to assign users
in group_A the ability to go into "configuration t"
but I do NOT want them to have the ability to peform
"no tacacs-server host x.x.x.x key cisco". Furthermore,
I would like to do everything via TACACS, I don't
want configure "privilege level" on the router itself.
Is that possible? Thanks.

Command Authorization Sets?Command authorization sets provide a centralized mechanism to manage TACACS+ administrative control. Driven by some of the largest enterprise and service provider networks that use Cisco Secure ACS, command authorization sets provide a method to group and name device command profiles that can be paired with users, groups of users, or network device groups. A key benefit of command authorization sets is the ability to remove any requirement of individual privilege level or command restrictions on each AAA client. This feature greatly enhances the scalability and manageability of setting device command authorization restrictions for network administrators.

AAA authentication / Radius-Servers

Hello cisco folks,
Have a technical question I would like to ask. I'm able to setup my 3750e switch to login through a radius server with my company user id and password but would like to be able to set it up that when I log in it drops me on the enable prompt. Right now I have to type >en.
Then the enable password. Thanks in advance.

Hi Bro
Yes, this can be achieved in Cisco IOS devices but not in Cisco ASA. In Cisco ASA, you still have to type the "enable" command.
Just ensure you've the configuration shown below, and all should be good;

Cisco Nexus AAA authentication and console access

We have nexus 7k with AAA authentication working now i have an issue i can't login using console port because my logins are rejected.Is there anyway we can login into console with local login details or we have to use ACS server (AAA) logins when connected to console (while ACS server is still reachable).
My main question is i want to login using console port while ACS server is still reachable is it possible?

Perhaps I am not understanding some parts of the original post and if so I would appreciate clarification of what I missed. But it seems to me that the main question in the original post is whether the original poster would be able to login on the console. And it seems to me that the high level answer is that yes login to the console should be possible. The details of how that would work are dependent on details of how the N7K is configured. If the original poster would provide some details of the configuration (especially all of the aaa authentication commands and the configuration of line con 0) we would be in a much better position to provide helpful answers.

AAA authentication when logging into the router via the web browser

Hi group,
I am trying to get access the a cisco 2621 via http and authentication
via AAA but there is something I am not quite understand.
I am using the freeware TACACS+ server running on RedHat Linux
Enterprise Server 3.0. I setup the TACACS+ account for myself with
enable privilege on the TACACS+ box. This account, let call it,
ddt123, can telnet/ssh into the IOS router and the enable secret
is associated with this account as setup in TACACS+.
Here is my configuration looks like on the TACACS+ file:
[root@dca2-LinuxES tacacs]# more tac_plus.cfg
accounting file = /var/log/tac_plus.log
key = zFgGkIooIsZ.Q
user = ddt123 {
member = admin
name = "ddt 123"
login = cleartext "exec123"
user = $ddt123$ {
member = admin
name = "ddt 123"
login = cleartext "privi123"
group = admin {
default service = permit
[root@dca2-LinuxES tacacs]#
Here is my configuration on the IOS device:
aaa authentication login notac none
aaa authentication login VTY group tacacs+ local
aaa authentication login web local enable

the it prompts me for authetication, which password should I use, "exec123" or "privi123"?
Can someone explain to me how this work, and if it works at all? Thanks.

Cisco Nexus to use Radius AAA authentication using Microsoft 2008 NPS

I have a Nexus 7010 running
Just wondering if you can help me with something. I'm having an issue with command authorization thru our aaa config. We don't have a problem authenticating its command authorization that is not working. From what I have seen and read Nexus NX-OS 6.x does not have any commands for aaa authorization unless you are configuring TACACS+. My basic config is below if you can help it would be much appreciated.
>>ip radius source-interface mgmt 0
>>radius-server key XXXXX
>>radius-server host X.X.X.X key XXXXX authentication accounting
>>radius-server host X.X.X.X key XXXXX authentication accounting aaa
>>authentication login default group Radius_Group aaa authentication
>>login console local aaa group server radius Radius_Group
>>    server X.X.X.X
>>    server X.X.X.X
>>    source-interface mgmt0
Also does anyone know how to configure Microsoft 2008 NPS as a Raduis server to work with Nexus? I have read a few post that suggest changing the
shell:roles="vdc-admin" in the Attribute Value field in the RADIUS server
Does anyone know if this works????
Thanks

I have never done this before with ACS but not with NPS. However, you are in the right path. Nexus uses NX-OS which is different in some regards to regular IOS. One of those differences is the AAA setup. In NX-OS you assign users to roles. So for full access you will need to return the following attributes from your Radius server:
Attribute: cisco-av-pair
Requirement: Mandatory
Value: shell:roles*"network-admin vdc-admin"
For more information take a look at this link:
http://www.cisco.com/c/en/us/support/docs/security/secure-access-control-system/115925-nexus-integration-acs-00.html
Hope this helps
Thank you for rating helpful posts!

NAS configure with 2 ip address failed on AAA authentication

I have routers configured with 2 bvi interfaces for dlsw.
When I configure NAS setting with 2 ip address, sometime the AAA authentication failed to prompt for user authentication.
Should I used ip tacacs source-interface?
If I configure only one, if that interface is down, then I will not be authentication using AAA even the second bvi interface is up.

Chee
The AAA server identifies the client by a single IP address and the client always needs to use that address as the source address. If you have 2 BVI interfaces it may be that sometimes the source address is one and sometimes the source address may be the other. That would account for the fact that sometimes it promts for user authentication and sometimes it does not prompt.
If using 1 BVI as the source address creates the potential that sometimes it might not work because that interface was down but the other BVI was up, then perhaps you should consider configuring a loopback address and using the loopback address as the source address. If the loopback was the source address then it would not matter which BVI might be up and which might be down.

Fixed ip for vpn user- aaa authenticated

Hi all,
i am using asa 5520 as my vpn box. All vpn users login to vpn box associated with a aaa server. The authenticaltion takes place on aaa server. If i use local database for user login, i can assign fixed static ip to the user via its vpn properties. But now i am using aaa for authentication and i want to assign fixed statix IP for some users. How can i do this?

with local aaa authentication
go to the user atributes
like username vpnuser attributes
vpn-framed-ip-address 192.168.50.1 255.255.255.255
this will give that ip to that user
if u are useing cisco ACS
under the user setting
go to :
Assign static IP address-If a specific IP address should be used for this user, click this option and type the IP address in the text box. The IP address assignment in User Setup overrides the IP address assignment in Group Setup
and the following link give step-by step intstruction to configure cisco ACS AAA

LMS 3.2 - Problem with inventory of switches using AAA authentication

Hi all,
we want to migrate our network equpiment from local authentication (telnet password, enable password) to AAA authentication (Cisco ACS server - username, password for priv level 15). The network devices are managed with CiscoWorks 3.2 and inventory works fine when device login credentials are telnet password, enable password.
I have configured a switch for testing the authentication to the ACS server, and tested the logon manually. After the successful test I reconfigured the device credentials in CiscoWorks and checked it by a device export with credentials. The credentials in CW were OK, but from this time CiscoWorks could't pull an inventory of the switch any more. Every inventory job failed.
Any help would be appreciated. Thanks a lot.
Regards
fred

Joe,
excuse me, I've made a mistake. It's the malfunction of the configuration *archiving* which depends on telnet services. I have included the trace file of the failed CW archiving job. I can see that CW receives the banner and the username prompt, but doesn't send back any telnet credentials. I have also checked the correctness of the device credentials by a DCR export.

AAA authentication for networking devices using ACS 4.1 SE

Hi!!!
I want to perform AAA authentication for networking devices using ACS 4.1 SE.
I do have Cisco 4500, 6500,2960, 3750, 3560, ASA, CSMARS, routers (2821) etc in my network. I want to have radius based authentication for the same.
I want telnet, ssh has,console attempt to be verified by radius server & if ACS goes down then it will be via local enable passwordf.
For all users i need to have different privilege levels based upon which access will be granted.
could u plz send me the config that is required to be done in the active devices as well as ACS!!!!

Pradeep,
Are you planning MAC authentication for some users while using EAP for others?
For MAC authentication, just use the following in your AP.
aaa authentication login mac_methods group radius
In your AP, select the radius server for mac authentication. You must have already defined your ACS as a radius server.
In your SSID configuration, under client authentication settings,
check "open authentication" and also select "MAC Authentication" from the drop-down list.
If you want both MAC or EAP, then select "MAC Authentication or EAP" from the dropdown.
Define the mac address as the username and password in ACS. Make sure the format of the mac is without any spaces.
You will not need to change anything in XP.
NOTE: XP normally does not require user authentication if machine has already authenticated but it might behave differently. If it does, I can let you know the registry settings to force the behaviour change.

AAA Authentication for Traffic Passing through ASA

I am setting up AAA authentication for traffic that will pass through my ASA. I am having difficulty enabling 'aaa authentication secure-http-client'. Without secure communications enabled access functions as expected. When I enable access, I get prompted for a username/password. The username/password is entered. Authentication passes (show uauth). The requested page (http://www.cisco.com) switches to https://x.x.x.x (a resolved IP address for the site). Eventually (5 seconds), I am asked to accept or deny a certificated. Interestingly, the certificate is for the ASA and not the requested site (http://www.cisco.com).
Am I missing something?

Aaa authentication for https access

I have several Catalyst 3750 switches that I'm running Tacacs on. I set the switch up to be an http server so that some of our admins could administer the switches through the web gui. Is it possible to login to the web console via your Tacacs login (in our case, our Windows username/password)? I found the "ip http authentication aaa" command but this doesn't seem to do it. I just don't want to share the local passwords if I don't have to.
Thanks in advance,
Eric

My experience of the web interface is that it uses the local password on the device and not the aaa authentication IDs and passwords.

AAA Authentication and VRF-Lite

Hi!
I've run into a strange problem, when using AAA Radius authentication and VRF-Lite.
The setting is as follows. A /31 linknet is setup between PE and CE (7206/g1 and C1812), where PE sub-if is a part of an MPLS VPN, and CE uses VRF-Lite to keep the local services seperated (where more than one VPN is used..).
Access to the CE, via telnet, console etc, will be authenticated by our RADIUS servers, based on the following setup:
--> Config Begins <---
aaa new-model
aa group server radius radius-auth
server x.x.4.23 auth-port 1645 acct-port 1646
server x.x.7.139 auth-port 1645 acct-port 1646
aaa authentication login default group radius-auth local
aaa authentication enable default group radius-auth enable
radius-server host x.x.4.23 auth-port 1645 acct-port 1646 key <key>
radius-server host x.x.7.139 auth-port 1645 acct-port 1646 key <key>
ip radius source-interface <outside-if> vrf 10
---> Config Ends <---
The VRF-Lite instance is configured like this:
---> Config Begins <---
ip vrf 10
rd 65001:10
---> Config Ends <---
Now - if I remove the VRF-Lite setup, and use global routing on the CE (which is okey for a single-vpn setup), the AAA/RADIUS authentication works just fine. When I enable "ip vrf forwarding 10" on the outside and inside interface, the AAA/RADIUS service is unable to reach the two defined servers.
I compared the routing table when using VRF-Lite and global routing, and they are identical. All routes are imported via BGP correctly, and the service as a whole works without problems, in other words, the AAA/RADIUS part is the only service not working.

Just wanted to help future people as some of the answers I found here were confusing.
This is all you need from the AAA perspective:
aaa new-model
aaa group server radius RADIUS-VRF-X
server-private 192.168.1.10 auth-port 1812 acct-port 1813 key 7 003632222D6E3839240475
ip vrf forwarding X
aaa authentication login default group RADIUS-VRF-X local

Why do we need aaa authentication enable

Hi all
Why do we need the " aaa authentication enable default group tacacs+ enable" . Is " aaa authentication login default group tacacs+ enable"
is not enough ?
aaa authentication login default group tacacs+ enable
aaa authentication enable default group tacacs+ enable
Thanks

Hi jatin ,
Just for clariffication , if i add " aaa authentication enable default group tacacs+ enable" , once authenticated device will go directly to enable mode .
As you said
aaa authentication login default group tacacs+ local
in case tacacs failed user has to enter local username and password . once it is authenticated
" aaa authentication enable default group tacacs+ enable " will be executed and the user have to enter the enable (local db ) secret .
Please correct me if iam wrong
aaa authentication login default group tacacs+ enable
aaa authentication enable default group tacacs+ enable
aaa authorization console
aaa authorization exec default group tacacs+ if-authenticated
aaa authorization commands 15 default group tacacs+ if-authenticated
aaa accounting exec default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
aaa accounting connection default start-stop group tacacs+

IDM Password Reset Authentication Questions

Hi,
We are implementing Password Self Service using IDM 7.1, everything is set up and we have tested and were able to reset password for users to connected target systems. we are now doing some cosmetic changes before going live, like
setting up new authentication questions and changing existing questions from IDM.
In total we have 10 questions and the way we set it is
Minimum number of validation questions = 5
No. of questions to show = 3
No. of answers required = 3
After setting all 10 questions, i took a new test id who was never set with a profile and set its profile with 5 random questions answers out of 10 and saved it, went back to /idm/pwdrest and entered the unique id which is the user id and the 3 challenge questions it showed up were not the ones i set my answers to.
Why is it prompting the questions for which i have not set answers to ?
Can anyone tell me if i am missing any config creating these attributes ?? or its the way IDM works ??
Thanks.

Greetings,
It has been my experience that the system will show any of the available questions when a user has not had any answers set. Sometimes, there is a disconnect with the Unique ID entered and the user ID stored in the identity store and it just cannot find the stored answers. As long as the additional question attributes you created follow the existing convention, they should be fine.
I would start by looking at what question attributes you have commited for the user and which ones show in the pwdreset task screen for the user. You can also run the guided task several times with the same ID to see what rotation of questions you see to see if it is going through all 10 or only a certain subset.
Do you have a self-service task configured to set the question answers?
Thanks,
Jared
