TACACS+ Authentication For Cisco NAM

Hi All,
I have an cisco ACS v5.1 and also a cisco NAM. Currently, I have configured TACACS+ on the NAM and the ACS v5.1 however when I try to access the NAM, the ACS v5.1 has an error message of "TACACS+ authentication ended with error" and I am not able to access the equipment.
For your information, I have no problem with others equipment TACACS+ authentication with the same ACS.
Please advise.
Thks and Rgds

I would first suggest that you verify that your ACS has an appropriate and correct entry configured for the NAM as a client. Assuming that is correct then I would suggest that you check and verify that the NAM is originating its TACACS requests from the address that you configured for the client on the ACS and that the shared secret is the same on both devices.
If those are correct then I would suggest to look in the Failed Attempts report of ACS and see if it provides a better identification of the problem.

Check_ntlm_password: Authentication for user ['name'] - ['name'] FAILED with error NT_STATUS_LOGON_FAILURE

Hi,
We are running a Mountain Lion Server with Open Directory / LDAPv3, as far as I can tell. My responsibility is to get my CentOS 6.3 box running Samba v. 3.5.10-125.el6 to authenticate users against the ML / OD box. I can ssh to the CentOS box OK and I can get Guest access to the Samba share to go OK too. Also, the OD passwords on the LDAP server are set to 'Open Directory' so I guess that means that they are encrypted and the Samba server is set to send encrypted passwords. But when a user tries to properly authenticate using either say via a Mac client Finder [Command-K], or smbclient, the Samba server will generate this message:
check_ntlm_password: Authentication for user ['name'] -> ['name'] FAILED with error NT_STATUS_LOGON_FAILURE
(I am blanking out the user name on purpose).
Of course there is more to the story, but those are the basics.
Here are the relevant parts of my smb.conf. FWIW, the CentOS / Samba box is called Jupiter.
Thank you,
NickZ

Turns out a printer driver installed on an XP (even W2K(?)) was (apparently?) flooding the OS X SMB server to the point of collapse. Uninstalling the "HP Tools" part of the driver cleared it up. The printer is an HP LJ1300. I had downloaded the full driver from HP.com. I don't know if any/all these conditions need to be matched, but: the printer was on the network using an HP print server JetDirect EX Plus, and the computer(s) in question were connecting directly to it (not via a print server). It's been too long ago, but there were always several errors in the System Log (Win XP Event Viewer) that correlated with the errors on the OS X server.
Proud to say that since that day (10+ months ago) I've not seen it happen again. whew.

TACACS+ configuration for Cisco ASA

I tired configuring TACACS+ configuration for ASA but unable to complete it. I have ACS 3.3 for all other Cisco Routers and Switches

Leo,
I was looking around and come across this post. It's very late, however, wanted to add my inputs for other community members.
RSA Token/One-Time-Password support available with ASDM only in SINGLE ROUTED MODE. If you are in Single Routed Mode, you can do OTP with ASDM if you are running ASA 8.2+ with ASDM 6.2+.
If the firewall is running in multi-context and transparent mode. It won't work. Below is the enhancement request that was filed for the same feature to be supported.
CSCtf23419 ASDM OTP authentication support in multi-context and transparent modes
With WLC is yet not possible and there is a enhancement request filed.

Certificate authentication for Cisco VPN client

I am trying to configure the cisco VPN client for certificate authentication on my ASA 5512-X. I have it setup currently for group authentication with shared pass. This works fine. But in order for you to pass pci compliance you cannot allow aggresive mode for ikev1. the only way to disable aggresive mode (and use main mode) is to use certificate authentication for the vpn client. I know that some one out there must being doing this already. I am goign round and round with this. I am missing some thing.
I have tried as I might and all I can get are some cryptic error messages from the client and nothing on the firewall. IE failed to genterate signature, invalid remote signature id. I have tried using different signatures (one built on ASA and bought from Godaddy, and one built from Windows CA, and one self signed).
Can some one provide the instructions on seting this up (asdm or cli). Can this even be done? I would love to just use the AnyConnect client but I believe you need licensing for that since our system states only 2 allowed. Thank you for your help.

Dear Doug ,
          What is asa code your are running on ASA hardware , for cisco anyconnect you need have Code 8.0 on your hardware with cisco anyconnect essential license enabled .Paste your me show version i will help you whether you need to procure license for your hardware . By default your hardware will be shipped with any connect essential license when you have order your hardware with asa code above 8.0 .
With Any connect essential you are allowed to use upto total VPN peers allowed based on your hardware
1) What is the AnyConnect Essentials License?
The Anyconnect Essentials is a license that allows you to connect up to your 'Total VPN Peers" platform limit with AnyConnect. Without an AnyConnect Essentials license, you are limited to the 'SSLVPN Peers' limit on your device. With the Anyconnect Essentials License, you can only use Anyconnect for SSL - other features such as CSD (Cisco Secure Desktop) and using the SSLVPN portal page for anything other than launching AnyConnect are restricted.
You can see your limits for the various licensing by issuing the 'show version' command on your ASA.

EIGRP SHA Authentication for Cisco ASA

Hi,
I was just wondering if anyone knew if Cisco was going to implement EIGRP SHA authentication in to the ASAs? My organization is migrating from classic to named EIGRP for SHA authentication and right now I'm stuck at the ASA's. Static routing everything just to remove MD5 authentication doesn't sound very fun, if you know what I mean. :)
Thanks!

Hello Mohammad,
I would recommend you to advertise them via EIGRP, better funcionality, escalability,etc,etc,etc.

Configuring TACACs Server for Cisco VPN 3000

Does anyone know how to get to the configuration setting to specify a TACACs server?

You need to be very careful when setting
up this thing. If the AAA server is down
for whatever reason, you will NOT be able to
log into the Concentrator again. As far
as the VPn3k console is concerns, it will
let you login with the "admin" account,
even though the AAA is up and running. In
other words, you can login from console
with both "admin" and AAA account at the same
time.
What a mess.

With Cisco Secure ACS For Windows TACACS+, authentication fails with AD

I am setting up a Cisco Secure ACS 4.2 server to act as a TACACS server for Switches and Routers I am using Windows 2003 server for the ACS,
and a Windows 2003 Active Directory server. The AD server is fine, as it is used for many other things.
I have set up ACS as defined nit he installation guide, including all the steps in the 'Member Server' section of the install guide
when using AD as an external database (i.e. setting up the services to run with a domain admin account, setting up a machine called 'CISCO'
on the domain etc).
I've set the unknown user policy to use the Windows database if the internal database doesn;t contain the user details.
If I add a user to the internal database, the authentication goes through fine, with an entry in the 'Passed Authentications' log,
02/24/2010,05:07:03,Authen failed,eXXXX,Network Administrators(NDG) ,X.X.X.X,(Default),Internal error,,(geting error message as INternal Error)
I've scoured google etc, and just cannot come up with any reason why this should be happening.
I've followed all the install guides to the letter. I need to get this up and running as soon as possible,
so am looking forward to finding out if anyone can help me with this one!
THanks and regards
Sharan

Hi Jesse,
Thasts a great answer and Soution.
My previous version was 4.2 and it was installed on 64 bit machine hence getting internal Error.
After this answer i have upgraded it to ACS4.2.1 and its started working fine
Thanks very much for the help

Problem setting 7606 router for TACACS+ authentication

Hello Support Community,
I have two Cisco 7606 routers which I have tried in vain to have users authenticated using TACACS+ servers. As shown below, I have two servers (1.1.1.1 and 2.2.2.2) reachable via vrf OAM which is reachable from desktops for ssh login. The true IP addresses and vrf have been altered because it's a company router.
I use the two servers to authenticate many other Cisco devices in the network they are working fine.
I can reach the servers from the vrf and the source interface in use. I can also telnet port 49 if the servers from the source interface and the vrf.
The server key is hidden but at the time of configuration, I can ascertain that it's correct.
The problem is that after confuring for TACACS authentication, the router still uses the enable password instead of TACACS. While the debug output shows 'bad password', why is the router not authenticating using TACACS? Why is it using the enable password?
Please study the outputs below and help point out what I may need to change.
PS: I have tried out many other combinations, including deprecated ones without success including the method suggested in this page;
http://www.cisco.com/en/US/docs/ios/sec_user_services/configuration/guide/sec_vrf_tacas_svrs.html

How to use tacacs+ authentication to assign a group policy at login in Cisco ASA

Hi everyone
As title, anyone knows how it works?
I only found it can work with LDAP authentication, but not in TACACS+
http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/98634-asa-ldap-group-pol.html#noaccessgp
please give me a hand, thanks.

Hi Karten,
I have the similar requirement and I used the ACS and configure Auth profile and map the RADIUS class (25) value as ASA group-policy name (even tried with tunnel-group name), but it does not work. It allows whatever vpn group that user select regardless of the user groups he belongs to.
I use two ACS local users and put them in two different groups and maped those two groups with two different Access rules in the ACS and pointed to correct Auth profile etc.
I am not sure what could be the issue and appreciate if you can advise.
thanks in advance.

Using ACS for Cisco Prime authentication

I'd like to use our Tacacs server running ACS to be the authentication method for user accounts in Prime, but don't even know where to start with this..
Any pointers?

The configuration on the Prime Infrastructure side is minimal: define the authentication server Prime is to use and select a mode for Prime Infrastructure to use with it.
Administration > AAA > TACACS+ Servers > add tacacs server.
Administration > AAA > AAA Mode Settings > tacacs+ and enable fallback to local.
The bulk of the configuration is on the authentication server side, particularly indefining groups, services and authorization tasks. This is covered in the "Performing Administrative Tasks" chapter of the Prime Infrastructure Configuration Guide, starting with the topic "Configuring ACS 5.x"
http://www.cisco.com/en/US/docs/wireless/prime_infrastructure/1.3/configuration/guide/admin.html#wp1595935
"Configuring ACS 4.x"
http://www.cisco.com/en/US/docs/wireless/prime_infrastructure/1.3/configuration/guide/admin.html#wp1625896
https://supportforums.cisco.com/docs/DOC-17909
In case it doesn't work, please get the logs from the ACS reports and monirtoring for tacacs authentication and error message while accessing cisco prime.

Device Name for Cisco Jabber

I found a document on Jabber Developer that explains all steps for the Cisco Jabber CUCM Setup Guide (http://developer.cisco.com/web/jabber-developer/jabber-sdk-cucm-guide), the phone type must be Cisco Unified Client Services Framework, everything fine, but says that the Device Name should be as ECP<username> when original setup guides says that must be as CSF<username>.
My users setup Device Name are as CSF<username>, but just to follow a best practice, should I change all Device Names to ECP<username>??
Regards,
Juan Carlos Arias

There's another thread on which someone mentioned some problems when using ECP for device name. Windows for jabber method of operation is the name of it. Do you have any configs using ECP??
Since I already have this in m lab working as expected i'll configure a couple of users with ECP and see if something changes, just wondering if you have something configured with ECP already.

Tacacs authentication fails for one user account for only one switch

Hi,
I am having an scenario, where as Tacacs authentication fails for one user account for only one switch.
The same user account works well for other devices.
The AAA configs are same on every devices in the network.

What could be the reason ?
No errors on ACS server; same rights had been given to the user account.
Thanks to advise.
Prasey

Hi there,
Does the user get authenticated in the ACS logs?
reports and activity----> failed attempts
ro
reports and activity-----> passed authentications
That will help narrow it down.

Radius authentication for privileged access

Hello,
          I have configured Cisco 6513 for radius authentication with following commands.
aaa new-model
aaa authentication login authradius group radius line
aaa accounting exec acctradius start-stop group radius
radius-server host <radius-ip> auth-port 1812 acct-port 1646 key 6912911
line vty 0 4
accounting exec acctradius
login authentication authradius
     This is working pretty fine. I want to configure radius authentication for priviledged access / for enable access.
     I am using TeKRadius as Radius server.
     Please help.
Thanks and Regards,

Hi Pratik
Sorry I mostly use only TACACS+ for AAA as it provides better granularity of access controls.
You'll need to make some specific changes to your RADIUS config so that nominated users ( the ones you want to be able to go to enable mode ) get put straight into enable mode upon login.
There's a guide here http://www.blindhog.net/cisco-aaa-login-authentication-with-radius-ms-ias/ which details the steps if you're using the Microsoft IAS radius server - you should be able to figure out that changes you need to make to your own server from there.

TACACS config for PIX & ASA

I am struggling in configuring the TACACS configure to allow authentication via Cisco ACS, I could able to configure for switches 2950,3750 but not with ASA & PIX, can any let me know the configs?

I am actually looking for a similar command which I used on the Cisco 2950/3750
aaa new-model
aaa authentication login default group tacacs+ enable local
aaa authentication enable default group tacacs+ enable
aaa authorization exec default group tacacs+ if-authenticated
aaa authorization commands 1 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 1 default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
with this commands I could able to track the command what all the user has used, logs with the user name which I configured on TACACS, the command which you have sent me I could able to login with the TACACS user name "aaa-server TACACS+ host " but it is not accounting all the details like login & logout time, command what the user has issued etc..
