Enable authentication for ASA

hi,
Im working on AAA authentication for an ASA (ASA 8.0(3) version) box thorough a TACACS+ server in ACS (4.2 version). The setup im working on includes several users in 3 classes: senior (privilege level 15), junior (privilege level 7) and monitoring (privilege level 0), user authentication and command authorization is working fine, however im having problems with enable authentication.
When an user of junior class try to authenticate the enable password the authentication fails, according to the ACS's log "Tacacs+ enable privilege too low", however the privilege level in ACS for this class is set to level 7. Checking with a sniffer i have find out that the TACACS+ message for authentication sent by ASA is setting the privilege level as level 15, as you can see in the attached screenshot. Of course if the ASA is trying to authenticate enable for a level 15, the authentication will fail according to user's current level.I have local authentication configured in the ASA and it works fine including enable authentication.
Anyone have had any issue with this or have any idea how resolve this issue?
thanks all for your replies.

Seems like you might be hitting bug CSCsh66748.
Hope you have tried "enable " command to enter enable mode for specific users.
BTW why are you using different privileges for enable when you already have command authorization in place.
Regards
Rohit

ASA enable authentication for AD user by ACS TACACS fails

In order to authorize command on ASA8.x for different users, I have to put 'aaa authentication enable console TACACS' into ASA configuration, and in ACS - user setup - TACACS+ enable password - Use separate password, I set an enable password.
It works fine for ACS local users, they are able to get into priv EXEC mode by entering 'enable' command and use my pre-set password, however, the password doesn't work for AD user.
So, how to setup enable authorization for AD user?
Or is there a way to drop a user directly into level 15 on ASA just like it on router?
below is the debug info.(I'm sure the password is the one I set in ACS)

I have run into a similar situation. I just want to authenticate via TACACS to enable mode in an ssh session. After using the "aaa authentication enable console TACACS LOCAL" command on the ASA, the ACS server rejects the password.
I have tried everything I can think of on the ACS as far as "TACACS+ enable password" using both a windows database or a separate password, and PIX/ASA command sets. I cannot go into enable mode unless I set the ASA to LOCAL authentication, which just uses the globally defined enable password.

How to Enable Authentication to Selected Users

1. How to enable SAP and AD authentication only for selected users in infoview login page ?
2. How to disable(remove) enterprise options in down arrow selection in infoview login page for some users?
We have to make some changes in web.xml?
Can anyone help me out.
Thanks!

You have to enable authentication for your application.
However, for the public pages, you disable this by setting the page's security attribute Authentication to "Page is public".

ASA - cut through proxy authentication for RDP?

I know how to set this up on a router (dynamic access-list - lock and key)... But, I'm having trouble understanding how to setup OUTSIDE to INSIDE cut through proxy authentication for RDP.
OUTSIDE to INSIDE RDP is currently working.
I have 2 servers I want RDP open for..
[*]OUTSIDE 1.1.1.1 to INSIDE 10.10.70.100
[*]OUTSIDE 1.1.1.2 to INSIDE 10.10.50.200
What's required for OUTSIDE users to authenticate on the ASA before allowing port 3389 opens? I was hoping for is a way to SSH into this ASA, login with a special user, then have the ASA add a dynamic ACE on the OUTSISE interface to open 3389 for a designated time limit. Is this possible?
Here is my current config.

You're running ASA 8.2(5). In 8.4(2) Cisco added support for what they call Identity Firewall rules. That is, you can make access-lists entries specific to users (or object groups containing users).
There's an overview document on this posted here. It's a bit dated but I believe the only change is that Cisco is now preferring use of the more current Context Directory Agent (CDA) - a free VM they provide - vs. the deprecated AD agent (software service that runs on your DC).

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?
firewall# show run aaa
aaa authentication http console TACACS+ LOCAL
aaa authentication telnet console TACACS+ LOCAL
aaa authentication serial console TACACS+ LOCAL
aaa authentication ssh console TACACS+ LOCAL
aaa authentication enable console TACACS+ LOCAL
aaa authentication match guestnetwork_access guestnetwork RADIUS
aaa authentication secure-http-client
firewall# show access-li guestnetwork_access
access-list guestnetwork_access; 2 elements
access-list guestnetwork_access line 1 extended deny udp 10.255.255.0 255.255.255.0 any eq domain (hitcnt=33)
access-list guestnetwork_access line 2 extended permit ip 10.255.255.0 255.255.255.0 any (hitcnt=412)
firewall# show run aaa-s
aaa-server RADIUS protocol radius

your definition for the aaa-server is different to the aaa authentication server-group

ACS with RSA for privilege level 'enable' authentication

Has anyone experienced problems with privilege level "Enable" password authentication via ACS using RSA two factor authentication? We have recently deployed ACS and use RSA two factor authentication for the telnet connection without any problems. When configuring the networking device and ACS to use RSA for the privelledge level authentication "enable" this fails. We get prompted to enter the token code and the RSA server indicates that authentication is succesful however the network device (ASA or switch) seems to reject it.
Are there any tricks to this?
Thanks in advance!

David
Like Collin the first thing that I think of is that you can not use the same token code to authenticate enable mode that was used to authenticate user mode. Beyond that I am not aware of things that should prevent this working. Are you sure that the ACS authentication server is configured to allow that user access to privilege mode?
Perhaps it would be helpful if you would post the config (especially all the aaa related parts) of a device that is having that problem. And it might help find the issue if you would run debug for authentication, try to login to enable mode, and post the output.

Enable Custom Authentication for License Server for Packager Server

How to enable processing of Custom Authentication for License Server for Packager Server?
Please give examples.

If I understand your question, you want to use the Flash Access Manager and/or the Watched Folder Packager (both are components of the Reference Implementation) to package content for a license server that uses Custom Authentication. To accomplish this, you need to use the Flash Access SDK to create a policy that specifies Custom Authentication is used. For example:
Policy pol = new Policy(false);
LicenseServerInfo licServer = new LicenseServerInfo(AuthenticationType.Custom);
pol.setLicenseServerInfo(licServer);
// set rights and other policy attributes
Once you create the policy, place the policy file on the Packager Server, and you can use this policy to package content.

Enable Kerberos Authentication for OWA only

Hi guys,
Having a customer that asked me if we can enable Kerberos Authentication for OWA only?
When reading various blogposts (official and unofficial sources) it seems that this is done for the whole CASArray which means every vdir right? Is this so and shall we instead aim for using kerberos for both MAPI/Outlook Anywhere and OWA?
Found this for MAPI clients: http://blogs.technet.com/b/exchange/archive/2011/04/15/recommendation-enabling-kerberos-authentication-for-mapi-clients.aspx
This seems to be more complicated?

Hi Fredrik,
Base on my search , I found an article which may give you some hints:
OWA publishing using Kerberos Constrained Delegation method for authentication delegation
This article is to show case how you would configure kerberos constrained delegation method for authentication delegation .We would use the OWA publishing post as reference.
Best regards,
Niko Cheng

Enabling HTTPS with Client Authentication for Sender SOAP Adapter on PI7.1

Hello All,
We are currently building up a HTTPS message exchange with an external client.
Our PI 7.1 recieved over HTTPS messages on an already configured Sender SOAP Adapter.
The HTTPS (SSL) connectivity works fine and was completely configured on the ABAP Stack at Trust Manager (TC=STRUSTSSO2)
Login to Message Servlet "com.sap.aii.adapter.soap.web.MessageServlet is required and works fine with user ID and password.
Now we have to configure the addtional Client Authentication.
At SOAP Adapter (Sender Communication Channel) under "HTTP Security Level"you are able to configure "HTTPS with Client Authentication".
But what are the next steps to get this scenario successfully in place?
Many thanks in advance!
Jochen

Hi Colleagues,
following Steps still have to be done:
- Mapping public key to technical user at Java Stack
As preparation you have to activate value "ume.logon.allow.cert" with true under "com.sap.security.core.ume.service" under Config Tool. At NWA under Identity Management at for repecively technical user the public key certificate
- Be sure CA root certivicate at Database under STRUSTSSO2
- Import intermediate Certificate under Certificate List at Trast Manager for the Respecive Server Note
- use Login Module "client_cert" which you have to configure under NWA\Configuration Management\Authentication for Components "sap.com/com.sap.aii.adapter.soap.app*XISOAPAdapter".
Many thanks to all for support!
Regards,
Jochen

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.

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.

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.

Command authorization for ASA

Hi all
I have configured ASA firewall for command authorization with ACS.For users with privilege level 15 it is working fine.But when i login with users with privilege level 0, first when i enter the username and password ,it enters into enable mode.But after that when i put the enable password ,it is not working.password is not working.I configured to use the same PAP password option in the ACS enable section for the user.Also is it possible in ASA is it possible when user enters username and password,he could directly log into the exec mode rather than enable mode and assign privilege for the user as configured in the ACS user configuration.
Thanks in advance

Enable authentication through tacacs+

I configured authentication for Enable to user Tacacs+. I need it to be authenticated the same time when users are logging in. That is, a user types his username and password, he is directly logged into Enable mode.
However, it stops everytime at exec mode, he has to type "enable " and type his password again to get into enable mode.
any idea?
The aaa config is attached.
thanks
Han

Han,
You need to add the "aaa authorization exec default group tacacs if-authenticated none" command. Also, the TACACS+ server should be configured to return the privilege level 15 attribute for Shell (EXEC) as well.
NOTE: The feature to get directly into enable mode after typing the Username/Password applies only for IOS devices. Cisco ASA does not include this feature as it is considered a security device.
Regards.
