RADIUS authentication question

Similar Questions

• WLC RADIUS aid Questions

  We would like to set up RAY of relief to ensure RADIUS authentications always go their primary ACS so that it is available, but the documentation is not very clear regarding the configuration of the user name.

  There is no mention of a password, but if you enable backup - even with the username default "cisco-probe", the failures of this account appear on the ACS server log, so I guess it doesn't.

  Can someone shed some light on how exactly this "cisco-probe" should work?

  Thank you!

  Fold in three ways:

  discount - no help

  passive - WLC sends the credentials to the server 'death' when a user tries to authenticate

  -You set up a user name and an interval.  WLC sends the credentials to the server 'death' at configured intervals.

  The password did not really, just that the WLC retrieves a package.  So getting back a rejection of the server would bring it "alive" in the list to the AAA.

  make sense?

• RADIUS authentication

  Hello world

  I want to implement RADIUS authentication for my companies Cisco devices. Could someone give me some examples of configuration of how to point my switches and routers on a RADIUS server, and also to try RADIUS authentication. Only by using a locally configured account if RADIUS fails?

  My undertsnading would be to use the following configuration;

  AAA new-model

  AAA authentication login default local radius group

  start-stop radius group AAA accounting network default

  RADIUS RADIUS-server host 1.1.1.1 key auth-port 1812 acct-port 1813

  RADIUS server retransmit 3

  Thanks in advance,

• WLAN 4402 for Radius Authentication

  Hi guys,.

  Please help me on how I can install my WLAN 4402 controller for Radius Authentication, if you have links or procedures that you can share, which will be very appreciated. :-)

  Thanks in advance.

  It depends on if you are using Cisco ACS or Windows IAS. Controller configuration is the same but the side RADIUS is different.

  Also what you are trying to configure, systems users, PEAP etc. through RADIUS

  PEAP via ACS is here

  http://www.Cisco.com/en/us/partner/products/ps6366/products_configuration_example09186a00807917aa.shtml

  PEAP via IAS is here

  Hope that helps

• RADIUS authentication for the switch using ISE

  Hi guys,.

  Someone did he do Radius Authentication for switch cli connection using ISE?

  We did it in our environment with ISE, but it is a challenge to give read-only access / Priv-1.

  If some users know the enable password, they can use and earn full privilege.

  Anyway to get around this other than to change the enable password?

  We have thousands of switches and won't change on each of them.

  If you have another method please advice.

  Thank you in advance.

  Well, you can set the "enable" function also be controlled via the AAA server with the following command:

  AAA authentication enable... This way server AAA will be checked for authentication for the secret to activate and use the local database as a last resort

  I hope this helps!

  Thank you for evaluating useful messages!

• RADIUS authentication problem

  I have a C6509 with switch IOS sup32 base. I also allows RADIUS authentication on the switch. But whenever I have telnet to the switch brings the following:

  Username: XXXXXXXX

  Password: XXXXXXXX

  Quick > activate

  User access audit

  Username: XXXXXXXX

  Password: XXXXXXXX

  I don't like the second username. I was expecting after the enable command, I should just be asked to enter my password and do not ask me a username again.

  Here is the version of IOS of the switch:

  s3223-adventerprisek9_wan - mz.122 - 33.SXH3a.bin

  Here is the config of aaa:

  AAA new-model

  AAA authentication login default group Ganymede + line activate

  the AAA authentication enable default group Ganymede + activate

  AAA authorization exec default group Ganymede + authenticated if

  AAA authorization commands 15 default group Ganymede + authenticated if

  AAA accounting exec default start-stop Ganymede group.

  orders accounting AAA 15 by default start-stop Ganymede group.

  Kind regards

• 5.2 ACS with different RADIUS authentication servers

  Hello

  I want to migrate from ACS ACS 5.2 4.1. I have already configured authentication GANYMEDE +, but now I've stuck to the RADIUS authentication for remote access WebVPN configuration. Please see the following diagram:

  

  I want to configure ACS to use Server Token WBS first. If authentication fails or the user is not found, ACS must use IAS in Windows Server. If this server fails also ACS must use internal DB. Additional attributes as belonging to a group or ACL downloadable should be taken from internal ACS DB.

  Is it possible to configure ACS like that? ACS 4.1 it is very easy to configure by selecting the per user authentication method.

  Thanks for your help!

  There is an option in the Advanced tab of definition 'RADIUS Identity server' th:

  This storage of identity differentiates between 'authentication failed' and 'user not found' when an authentication attempt is rejected. Among the options below, select how a rejection of authentication of the identity store must be interpreted by FAC for the politics of identity of treatment and reports.
  Releases to treat as 'authentication failed' treat dismisses them as "user not found".

  In order to continue in the sequence, I think you have to select the option "user not found".

• Using CHAP with RADIUS authentication

  Hello

  I configured a Cisco 877 router to send the RADIUS requests when a user connects to the console (Console line) or VTY Line using the following configuration:

  AAA new-model

  Group AAA authentication login default RADIUS

  Group AAA authentication ppp default of RADIUS

  RADIUS-server host 10.0.0.1 auth-port 1812 acct-port 1812 mysharedkey key

  When I connect the RADIUS packets I see the Cisco router sends the initial AccessRequest using PAP.

  How can I configure my router to send it's original AccessRequest package with CHAP?

  My apologies if this has already been discussed, I searched high and low for an answer.

  Thanks in advance.

  John

  Hi John,.

  PPP connection supported by CHAP because a configuration command to activate the CHAP protocol as Protocol of stimulus / response. However, the Console VTY connections and to THE will always go on PAP when using RADIUS authentication. There is no command to activate the CHAP protocol for these types of connections.

  Best regards.

  You must post a few outings until I'd suggest something. If SSH works very well with the local database which means the keys RSA are fine.

  If you can't attach the executed full show. Attach the bottom of the outputs listed in your next reply.

• VPN Site to Site Secret shared and can co-exist RADIUS authenticated VPN?

  Hello

  I have a setup VPN site to site between two offices on 515Es PIX (v.6.2 software) and has recently added a vpngroup/shared secret based VPN remote access to one of the offices. Given that just forced me to add a number of different policies to my existing crypto card, it was a plant direct and easily implemented. For more security, I want to use a RADIUS server to give to each remote user their own connections and profiles rather than a group on all password is configured. To do this, however, it seems that I have to add the following additional commands to my existing crypto card:

  client configuration address map mymap crypto initiate

  client card crypto mymap RADIUS authentication

  These do not correspond to the policy number (my site-to-site is 10, and remote access policy is political 20), so I don't know what the effect would be if I added the. It would cause my connection from site to site for authentication RADIUS request (a very bad thing)? If so, do I need another interface to bind a new encryption card to? The answer to this would be greatly appreciated!

  Also, if anyone knows an example configuration for a similar configuration, I can look at, please let me know! Thank you.

  -A.Hsu

  For the site to site connection, you change line isakmp keys and add the parameters of "No.-xauth No.-config-mode" at the end of this one, which tells the PIX not to do the auth RADIUS or assign an IP address, etc. for the specific site-to-site tunnel.

  Example of config is here:

  http://www.Cisco.com/warp/public/110/37.html

  Note that there is no command options I have just said, I just sent an email to the web guys to fix this. Basically, your config will look with the options "No.-xauth No.-config-mode" on the line «isakmp x.x.x.x key...» "for LAN-to-LAN tunnel.

• Client VPN authentication question

  Hi friends,

  I recently started a new company, where the Cisco VPN Client is used by all remote Windows users. I'm not familiar with the customer. I see by our remote access policy that clients authenticate using PAP. This immediately caught my concern.

  My question is if this poses a threat to security? Even if the authentication is not encrypted, it is always the case in a 3DES IPSec tunnel, right? What is the best practice regarding using the VPN client and authentication?

  Thanks in advance!

  Equipment:

  Cisco VPN Client v5 (latest version) on Windows XP SP3

  Microsoft IAS (RADIUS) on W2K3 Server R2 x 64

  Router Cisco 3825

  IOS 12.4.24T Adv IP Services

  If I understand your customer VPN ends on 3825 router. the customer gets the name of username/password prompt after than phase 1 so it may not be clear.

  I hope this helps

• AAA authentication question

  Here is the config, I have a switch:

  AAA authentication login default group Ganymede + local

  AAA authentication login vtylogin group Ganymede + local

  AAA authentication login conlogin group Ganymede + activate none

  the AAA authentication enable default Ganymede + activate

  Now, here are my questions:

  1. when I have my login of Ganymede console connection works, but when I type 'enable' and try to use my password to Active Directory, it does not work.  So I try the enable password, don't worry.  However if I change the 4th line "aaa authentication enable the Activate by default", I can now by using the enable password.

  2. my second question is when I SSH into the switch, I want only that it uses the RADIUS server and use only the database local when the Ganymede is not available.  However while Ganymede is available, I am still able to login using the local user account.  I guess that's by design?  Is there a way to prevent this if it isn't design?

  When you use the local user account to connect to the device, can you check if you can see the log in "past the authentication attempt" on the box of the CSA? If so, the same account could you please check your local ACS DB user to see that it was created by a fake?

• RADIUS authentication to activate PW

  Hello world

  I have my authentication RADIUS working for login password but not the enable password. My config is lower;

  AAA new-model

  AAA authentication login default local radius group

  start-stop radius group AAA accounting network default

  When I add the command;

  AAA authentication enable default group enable RADIUS

  I expect he allow me to enter my pw of RADIUS to activate a to, but it doesn't. And does not allow me to enter the configured locally?

  Any help would be great,

  Thank you

  Dan

  Hello

  Usually the RADIUS is not used the device management - because most of RADIUS servers do NOT have the proper authorization.

  Same Cisco ACS doesn't do much in the way of authorization for the RADIUS.

  IAS is not any notion of IOS activate. IAS will also want to make default MSCHAP. Enable authentication is basically PAP. So you have IAS to authenticate using the text that excludes practically using ad a return that will end unless you store the user in the format "reversably" encrypted passwords within the AD.

• Windows 7 slow login / delay authentication question user wireless via ACS 5.8

  Just set up a new ACS 5.8 farm (only 2 servers) here and which I hope someone here can shed light on the difficulties.

  The new ACS server is set up to correctly authenticate administration network device and I am currently working on the definition of profiles for our wireless users authentication and business laptops.

  Being new to this version of ACS (we will migrate manually ACS 4) I followed an excellent example of this task described in a video on this site: http://www.labminutes.com/sec0044_ise_1_1_wireless_dot1x_machine_auth_peap

  I managed to have a Windows XP sp3 client authenticate properly, first with the authentication of the computer, then the authentication of users... and the domain logon process takes place in a short period of time< 1min="" and="" the="" user="" gets="" all="" their="" networked="" drives="" via="" the="" domain="" login="">

  However, I'm fighting to get our Windows 7 clients to authenticate properly.  It seems that the machine authentication does not work as expected (I can ping the laptop test from another machine on the network while the test machine is sitting at the login screen; and I see Authentication host recorded in the papers of authentication Radius ACS).  But, when a domain user logs in with his credentials, the connection process takes 4-5 minutes before an event to authenticate the user is entered in the register authentication Radius ACS, after which the login process completes, except that the domain logon script does not work and the user does not receive the drive mappings.

  Can someone point me in the right direction here?  I would be grateful any entry on this.

  Thanks in advance,

  John

  I had a similar problem with Wireless 802.1 x Win 7 clients unable to connect unless they had cached credentials of the AD.  Authenticate in the machine, but the user would take a lot of time if the Windows credentials have been cached.

  I could solve the problem by expanding the ACL of the air space used during the user authentication to include all DC in the environment.
