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.

  • Aaa authentication enable default group tacacs+ enable

    I am implementing CSACS 4.0. First on the client, I will apply aaa authenticatio/ authorization under vty. The issure if I use the followin command
    aaa authentication enable default group tacacs+ enable
    what will happen if I login via console? Will I be required to enter any username/password?
    Below is my configuration
    aaa new-model
    aaa authentication login authvty group TACACS + local

    Any suggestion will be appreciated!

    It should work because this is a message.banner prompt everytime you try to login (console/vty). I have it configured on my router.
    If you have banner motd, it will be displayed as well (see below). So I ahve to remove it to get only the aaa banner & prompt being displayed:
    *** Username: cisco, Password: cisco (priv 15f - local) ****
    Unauthorized use is prohibited.
    Enter your name here: user1
    Enter your password now:
    Router#
    The config more or less looks like:
    aaa new-model
    aaa authentication banner ^CUnauthorized use is prohibited.^C
    aaa authentication password-prompt "Enter your password now:"
    aaa authentication username-prompt "Enter your name here:"
    aaa authentication login default group radius

  • Privilege mode authentication using Tacacs for Cisco Routers

    I am trying to set up a test environment where I need to be able to be asked for both a username and password while entering enable mode from exec mode on a cisco IOS router. I was told the only way to do that is through Tacacs. But I've not seen any such configuration options on Tacacs in order to set it up right. Has someone ever did a setup like this before. I would appreciate any help on this. Thanks.

  • NX-OS and enable authentication

    I am trying to secure a few Nexus switches with tacacs+  I am able to authenticate logins but I don't see the command for privileged mode, for example on a 2960 switch it was; aaa authentication enable default group tacacs+ enable
    Was this removed on the NX-OS software?      

    Hi David,
    I agree with Chris. Exec authorization by-deafult enabled on NX-OS. The below listed commands are replaced by Role based access (RBAC).
    aaa authentication enable default group tacacs+ enable
    aaa authorization exec default group tacacs+

  • 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.

  • FWSM: AAA authentication using TACACS and local authorization

    Hi All,
    In our setup, we are are having FWSMs running version 3.2.22 and users are authenticating using TACACS (running cisco ACS). We would like to give restricted access ( some show commands ) to couple of users to all devices. We do not want to use TACACS for command authorization.
    We have created users on TACACS and  not allowed "enable" access to them. I have also given those show commands locally on the firewall with privilege level 1. and enabled aaa authorization LOCAL
    Now , those users can successfully login to devices and execute those show commands from priv level 1 except "sh access-list".  I have specifically mentioned this
    "privilege show level 1 mode exec command access-list"  in the config.
    Is there anything i am missing or is there any other way of doing it?
    Thanks.

    You cannot do what you are trying to do. For (default login you need to use the first policy matched.
    you can diversify telnet/ssh with http by  creating different aaa groups.
    But still you will be loging in for telnet users (all of them) using one method.
    I hope it is clear.

  • User authentication through cx module

    Hi,
    I am using cx module in ASA for context aware security. I want to also enable authentication for Internet users who pass through cx module and that authentication must be from active directory.
    Can anyone please guide or share any document which tells how to configure cx for it? Thanks a lot.

    Check the config guide for cisco cda. It will provide the auth between cx and AD. You can also check my blog for hints and tips.

  • EDQ authentication through Novell

    We are currently using AD as our authentication platform for EDQ. We need to set up additional configurations for authentication through Novell. Has anybody done this? What is different from the AD configuration?
    Thanks
    Craig

    Hi Craig,
    Apologies for the late response on this. I believe an SR has been logged, and a response will be available on the SR very shortly.
    Some basic notes are as follows. The examples files are missing below (but will be on the SR):
    EDQ does not have out of the box support for Novel eDirectory. However it can be configured easily. To do this, you need to define a ‘realm’ with connection details for the eDirectory server and an associated ‘profile’ defining the LDAP search filters and attributes to use with the eDirectory.
    All this information can be added to the login.properties file but it is sometimes simpler to define the information in separate files. Realm information can be define in files in the realms subdirectory of the security directory and profile information can be stored in the profiles subdirectory.
    These are the steps:
    1. In the login.properties file, add a realm ‘edir’ to the realms list:
    realms = internal,...,edir
    2. Create a directory realms in the security directory and store the attached edir.properties there. Amend the file with:
    •     The LDAP server address. The example file has 10.8.1.182.
    •     The correct LDAP domain information. The example file users the domain o=rde
    •     The DN and password of the user used to connect to LDAP. The example has cn=rde,ou=users,o=rde
    •     The LDAP group used to contain EDQ users. The example has testgroup
    •     If the server has a certificate installed, uncomment the ‘ldap.security’ line to enable SSL connections
    3. Create a directory profiles in the security directory and save the attached novell.properties there. This file is suitable for a standard eDirectory setup and should not need any changes. It assumes:
    •     An objectClass of inetOrgPerson for users
    •     An objectClass of groupOfNames for groups
    •     The unique ID of user and group entries is the GUID attribute
    The profile can be tweaked if these assumptions are not correct.

    Mike

  • Centralized authentication through insecure net, ASA

    Hi all,
    I'm looking for some ideas, products e.g. that can help me to achieve the following scenario:
    - We have several customers with Cisco ASA
    - We want to provide our IT-Engineer staff a remote vpn access to each customer site
    - We need a centraliced AAA for the enginer vpn-authentication (TACAC+, RADIUS e.g.)
    - The centralized authentication server should be on our site. So each ASA (customer site) has to do the authentication
       through the insecure internet to our AAA server
    - Site-to-site is not an option (several customer sites have the same IP-range)
    Any ideas?
    Thanks a lot,
    Norbert

    Norbert
    I would look at using certificates for this. So each customer ASA uses your centralised certificate server for authentication.
    You can use something like Microsoft CA server to act as the certificate server.
    There are plenty of docs on Cisco site for using certificates both with the VPN client and the ASA.

  • How to capture userinfo after a partner application is authenticated through SSOSDK?

    I have successfully installed and deployed the Partner application for Portal using SSOSDK. My question is, once the user is authenticated through SSOPartnerServlet.java and gets thrown back to the partner app(PAPP), how do we get the user info(i.e. username) from the PAPP?
    Is there an API?
    I have already asked this question from oracle tech and they told me to post it
    Thanks,
    Hamid

    Pass the name of a subrotine to handle your user commands to the fm parameter.
    I_CALLBACK_USER_COMMAND = 'USER_COMMAND'.
    Then code for the user command function,
    form user_command using r_ucomm type sy-ucomm.
    case r_ucomm.
    when '<FCODE of your button>'.
    Code your logic....
    endcase.
    endform.
    To add your button using your own pf-status, you should copy a standard gui status and modify it.
    To trigger this pf-status you should pass routine name to I_CALLBACK_PF_STATUS_SET.(I_CALLBACK_PF_STATUS_SET = 'SET_PF_STATUS..)
    form set_pf_status.
    set pf-status 'ZSTAT'.  "THis ZSTAT must be created by copying a STANDARD pf-status of say some std program like SAPLKKBL. and then modifying it.

  • Enabled monitor through override not visible in custom management pack

    Hello Everyone,
    I've this requirement to enable a monitor which is disabled by default in its source sealed management pack. Using following article; via override; I enable the monitor and place it into a custom unsealed management pack.
    https://technet.microsoft.com/en-au/library/hh212818.aspx
    Now when I try creating subscription based on that monitor; and select the custom unsealed management pack; that monitor is not listed/available. However, this same monitor which is turned enabled by override; is listed; if its parent sealed management pack
    is selected. 
    Questions:
    1) Would selecting this monitor from its sealed management pack; safe to assume this monitor is now enabled? 
    2) Is this default behavior for monitors turned enabled via override? 
    Please provide input to this, how an enabled monitor through override can be referenced to be used? Thank you.

    1) If the override is done properly, yes, it is enabled. You can check that it is actually enabled by opening the health explorer of an object targeted by this monitor : it should be green/yellow/red instead of blank when it was disabled
    2) It is the default behavior. What happens is that you store the override (just a parameter that says "ok, the monitor is now enabled") in the unsealed management pack, not a copy of the actual monitor.

  • How to do .1x port based network access authentication through ACS

    How to do .1x port based network access authentication through ACS.

    Hi,
    802.1x can authenticate hosts either through the username/password or either via the MAC address of the clients (PC's, Printers etc.). This process is called Agentless Network Access which can be done through Mac Auth Bypass.
    In this process the 802.1x switchport would send the MAC address of the connected PC to the radius server for authentication. If the radius server has the MAC address in it's database, the authentication would be successful and the PC would be granted network access.
    To check the configuration on the ACS 4.x, you can go to http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.1/configuration/guide/noagent.html
