Cisco :: Enable Password Fails In AAA Authentication Method List?
Jul 15, 2011
I've got a weird problem that I can't figure out. I've de-authorized the switch in the RADIUS server to force an ERROR status to test the backup entries in the AAA authentication method list. However, after I do that and try to log in (through ssh), it just prompts me for my username's password and not the enable password. Here's the debug output:
1d02h: RADIUS: Marking server xxx.xxx.xxx.xxx:1812,1813 dead
1d02h: RADIUS: Tried all servers.
1d02h: RADIUS: No valid server found. Trying any viable server
1d02h: RADIUS: Tried all servers.
1d02h: RADIUS: No response for id 10
I've got a strange problem here. In the office, my OEAP 600 can join WLC if there is no MAC authentication. When i enable MAC authentication at WLC, AP will fail to register. However, I try it at home and it works with both MAC authentication enable or disable. I suspect it is because of firewall in my office, but there shouldn't have any different in discovery and joining procedure for AP with MAC authentication enable or disable.
Any instructions to configure an ASA to allow authentication by certificate only on an AnyConnect vpn?I'm running an ASA 5505 with 8.4(1) and AnyConnect 2.4.7030 on an Android phone.I currently have the AnyConnect client connecting ok using username / password for authentication.
I have loaded the company root certificate (internally generated) into the ASA "CA Certificates" and generated an Identity Certificate for the ASA.
I have been successfully able to setup Cisco AnyConnect VPN on ASA 5520 with 8.4 code. I have set it to authenticate against the RADIUS Server (Microsoft Windows 2008 NPS server). I have noticed one thing, on the server under "Constraints and Authentication Method". I picked MS-CHAP-v2, but it is considered Less secure authentication methods. I can click on Add and choose other Authentication methods like Smart Card or other Certificate, PEAP, EAP-MSCHAP v2. I picked PEAP but then the VPN does not work.
So first of all does it really matter if I just leave it to MS-CHAP-v2? Because from my understanding is that AnyConnect will authenticate to ASA and then ASA in the backend talks to the RADIUS server so from a security stand point this scenario shouldn't it be sufficient as no un encrypted or less secure information is available to the outside world? Secondly is there any documentation on using PEAP with Cisco AnyConnect?
I configured WiFi connection on Windows XP and Windows 7 with EAP-TLS (using Cisco WLC 7.0.235.3 and Cisco ACS 5.2.0.26.10). It is configured with computer authentication and computers certificates are autoenrolled from Microsoft PKI.It works well!
Now I configured Windows 8 with same configuration.First authentication works but if I manually disconnect and reconnect, I got this error on ACS: 22047 Principal username attribute is missing in client certificate.In EAP packets, we could see that Windows 8 sent a TLS session ticket but session was not resumed correctly by ACS..On ACS configuration, we checked this option "Enable EAP-TLS Session Resume" with session timeout "7200".
Running ACS5.2, Windows XP Pro, Window Server 2003 and Cisco Anyconnect Client. When the machine name password changes between the PC and the AD server the ACS will error out with "24485 Machine authentication against Active Directory has failed because of wrong password".TAC has been working with us on this and sees the error in the logs but does not have an answer on with to do to solve this. It has the same problem with Wireless Zero. Once the PC is rebooted the error goes away for 30 days. We are in a hospital setting so this is a not just a minor problem
I'm trying to set up vpn with ASA 8.2(5) and Anyconnect 3.0.4235. The goal is to force user to connect from registered machines only (winXP & win7 x32 and x64). To do this, I used machine certificates issued by own CA. Certificate is installed in machine store. I use double authentication (aaa & certificates). Everything works fine, AnyConnect browses cert store, ASA validating machine certificate, then user is prompted for username/password and finally if all is correct - connection is established.My problem is, that for new installation (new host), AnyConnect fails at first connection attempt. If I use aaa authentication only, connection is established, but if I use aaa & certificates - connection fails. The appropriate .xml profile is predeployed at client host asa well as machine and root certificates.Important: When first try (aaa auth) succeded, others are always OK (with aaa. certificate or aaa & certificate authentication). Only the first one fails.The goal is to succesfuly establish connection with aaa & cert.
With DART i get: ****************************************** Type : Error Source : acvpnagent Description : Function: CTransportWinHttp::WinHttpCallback File: .CTransportWinHttp.cpp Line: 2150
[code]....
Certificate is valid for sure, and as I mentioned before, if first use aaa only, the second try is OK. At ASA with debug crypto ca 255 can't see any certificate from client.
I am running Cisco ACS 5.1 802.1x with certificate based authentication for Wired and Wireless connections. The issue that I am having is that when a user comes in from home with their laptop the wireless connection works, they pass the authentication and have network access fine. But when the plug the laptop into a docking station the LAN connection fails and gets put in the Auth Failure Vlan. A reboot of the phone/ shut/no shut fixes this, but I really need to find a resolution.This is an intermittent fault and only effects users with both LAN and WLAN enabled. Running ACS 5.1.0.44, all Cisco 3750s - c3750-ipservicesk9-mz.122-55.SE.Certificates are issues by group policy and only using computer authentication.
I have a problem with a customer of mine. We have deployed two new WLC5508 running r7.0.116.0 and AP1142s, also WCS with r7.0.172. When we setup a "Guest Access" we ran into trouble.The problem is that we can associate to the SSID/AP and get an ip-adress. When we open the web- browser we do not get redirected to the virtual interface but instead the _hostname_ of the WLC. Like this: url...
I we manually replace "cisco6a19c4" with 1.1.1.1 it works as it should, the login page appears, we login and can access the internet.We have tested and disabled web-auth on the ssid an everything works, we can directly go out on the internet, DNS works without any problems. [code]Guest network (VLAN) is transfered from WLC via the trunk to the Cat4503 and then connected on a access-port to a separate broadband-router, then to the inetrnet.DHCP to guest-users from separate broadband-router which is def gwy and "DNS".On the virtual interfaces no hostname is configured.
I set up LDAP store pointing to a Windows domain and am testing authenticating users via an ASA. In my LDAP config, its set for "Groups Objects refer to subjects" and I selected usernames in the drop down. I also added a a Global Group to the Directory groups tab in the LDAP store that I created.
Under my Access Polices, I created a rule that meets two condititons - coming from the ASA, and then I was able to select the group from the drop down box for my ldap domain. As a condition, it shows up as DomainName:External Groups. I set the permission to Permit Access.
Originally, I was failing authentication and I was receiving Subject Not Found in Store. I adjusted the Identity Sequence and now I receive a the following error:
15039: Selected Authorization Profile is Deny Access. So it must not be associating my account with the group with the Permit Access and using the Default Permissions.So it does match the correct Access Service, and Identity Store.
I have setup the WLC to authenticate to a MS Server2008 NPS for a WPA2/AES SSID. The connection is successful, but client authentication fails for wrong EAP-type. I believe this indicates a Windows7 client issue. What is the required client setup to satisfy the MS NPS?
Just purchased an E2000 (Firmware version 1.0.03) to use with DDNS. Much to my surprise there seems to be a problem with saving the password at the configuration screen. [code] With the above settings entered and the Update button pressed favorable results are obtained; the router reports that DynDNS.org updates okay. However once the "Save Settings" button is pressed an update fails with the error "Authorization failure bad ID or password".Is anyone else experiencing this issue? Is the password field limited to certain characters?
We would like to enable IS-IS HMAC-MD5 authentication on an production network for LSP authentication including LSP, CSNP and PSNP. The problem is that when we are applying the command "authentication mode md5" under the isis process there is authentications failure and the router loses all routes from routing table. Is there any way to enable authentication without the router losing the routing or to "delay" the authentication until all routers are configured.
how to Config the ACS 4.2 server runs in TACACS + mode (users accounts configured the ACS) mode to authenticate enable mode password on the asa using the same AD account?
I have a 3845 router. Setup SSH Version 2generated rsa keys (1024)set login localtransport input ssh and telnet is enabled since I can't get ssh connection working When I connect using SSH, I get the following error. server refused authentication protocol.
We have ASA configured in multi context mode, with software 8.4(2) configured for AAA Configuration is admin context as follows:
aaa-server TAC protocol tacacs+ aaa-server TAC (management) host 10.162.2.201 key ***** aaa authentication enable console TAC LOCAL aaa authentication http console TAC LOCAL aaa authentication serial console TAC LOCAL aaa authentication ssh console TAC LOCAL
Because of multiple context, after logging in we enter System context. Console port authentication is working fine except access to privileged mode while connecting over console port. After issuing "enable" command ASA accepts only configured enable secret in system context and changes user ID to enable_15, so we are unable to do user-level command authorization and accounting.It seems that ASA in system context is not aware of any AAA configuration, and there isn't any command to configure AAA in system context.Is there any way to configure enable authentication over AAA in system context?
Can we enable ssh on 3500 /3600 APs along with use radius for login authentication? idea here is to that ssh will provide another method to access the AP for troubleshooting purposes.I know with autonomous mode APs this should not be an issue but not sure with lightweight APs.
I successfully authenticate through ACS to my Identity Store, but only get dropped into a non-enable prompt: ciscoasa> How can I get an Authenticated user directly into enable mode?
We're in the process of implementing an ISE 1.1 server for Guest Wireless Access / BYOD at our company and ran into an issue with authenticating from iPhones / iPads when the account is set with 'change password on next logon' (it's a local account created on the ISE server - not AD). It fails and displays 'unable to join network' on the iPhone. The ISE log shows a '5411: No response received in 120 seconds'. We're able to authenticate from Windows devices and are prompted to change the password during the authentication process. If we unchecked the 'change password' box we can authenticate from iPhones & iPads without any issue but we need to have a way for users to set their own password.
configuring AAA on 1841 router, initially it authenticates me well using my TACAS+ login. but though i have configured enable password in router, router directly puts me in privilage mod without asking enable password .
my configs for AAA as below
aaa authentication login ACS group tacacs+ local aaa authentication enable default group tacacs+ enable aaa authorization config-commands aaa authorization exec ACS group tacacs+ local aaa authorization commands 0 ACS group tacacs+ local aaa authorization commands 15 ACS group tacacs+ local aaa accounting commands 1 ACS start-stop group tacacs+ aaa accounting commands 15 ACS start-stop group tacacs+
How to configure authentication of enable password using acs 5.3. I have installed acs 5.3 and created user and gave relevant passwords. Following config is done on router
aaa new-model aaa authentication login default group tacacs+ local aaa authen enable default group tacacs+ enable tacacs-server host x.x.x.x key xxxxx
Now when I telnet router, i can authenticate username/pass with acs5.3 but when i try to enter enable command and give password, it gives me error in authentication. What is the process of configuring enable passwords?
I need to recover switch enable password, i have already configured AAA also, when i am tryig to follow below proceedure finally saying Authorization failed. how can i recover enable password,If I try to recover password like this description says [URL]
Step 1 Connect a terminal or PC with terminal-emulation software to the switch console port.
Step 2 Set the line speed on the emulation software to 9600 baud.
Step 3 Power off the switch. Reconnect the power cord to the switch and, within 15 seconds, press the Mode button while the System LED is still flashing green.
Base ethernet MAC Address: 00:0x:xx:xx:xx:xx Xmodem file system is available. The password-recovery mechanism is enabled.
The system has been interrupted prior to initializing the flash filesystem. The following commands will initialize the flash filesystem, and finish loading the operating system software:

I have migrated my ACS data from 4.1 to 5.1 and everything is working fine to test the connection I have configured a switch to get the authentication from the new Tacacs server, using my old username and password..i got in perfectly but when the switch asked my for enable which is the same password, it refused the password.(I have unchecked the <use a different password for enable> option) I deleted my switch from the Tacacs to enter locally, I went in with no problems..i thought that the problem may be from the old configuration.so I created a new username and password to check, and the problem still exist.
Today I wanted to change my passwords on my router Cisco 888e.I connect by telnet my router and access the enable mode.Then, I set my enable password to passwordxxx with the command enable password password1.After a show run, i could see in this config my new password correctly set. Then, I set my enable secret password to passwordxxx (the same) with the command enable secret password password1.I log off the enable mode.Try to log on with the command en but when I type the new or the old password, I receive a 'Access denied' message.
And I'm sure of the new one because on my command line to define it I could see this new password in clear!What are my solutions to access the enable mode again?If I reboot my router, it'll run the previous config file with the old password? I've only worked on the running config file and haven't apply these changes to the nvram.
We are installaing a new RSP720 on 7606 platform and facing a peculiar problem. It is prompting for a enable password. We have not configured anything on router yet, still it is asking for enable password.
I have a problem with an ASA5510 (8.0.4) firewall in South Africa (I'm in the UK).It's a replacement firewall that I am trying to configure remotely through a serial device with an internet facing connection, but the enable password is not working.I can connect to the device OK, type 'en' and when propted for the password whatever I use (blank, cisco, Cisco etc.) I get an 'invalid password' message.
Changed my AD password and now i cannot get into the enable side of the cisco switches on our network (we have no routers).Looking on the logs for the ACS v4.2 I can see the following -
On TACACS+ Accounting you can see the connections which have worked - it the initial tty connections -
When i look in the failed attempts i see the following Auth failed - External DB user invalid or bad password or on another occasion internal error or EAP-TLS or PEAP authentication failed due to unknown CAcertificate during SSL handshake.
I have been experimenting with acs 4.2 and a cisco asa 5510. I have managed to authenticate the ASA users with my tacacs server. The user "test" is authenticated with the tacacs server, and can log in. But the enable password is wrong, because i dont know where to place it in the tacacs server.
Now my question is, where do i set my enable password when authenticatig with tacacs+. And for this i mean in the acs 4.2, i know how to do it on the asa.
