Cisco AAA/Identity/Nac :: Command Auth Failure On ASA5510 Using ACS5.1
Jun 11, 2012
I'm having trouble getting things working on a pair of ASA5510's using Cisco Secure ACS v5.1. We were previously using a much older version of ACS to these (and a lot of other) devices which worked OK for remote access for read/write use. Am in the process of migrating to the new ACS software and have got it working OK to everything (many Cisco switches and other IOS devices) except these ASA5510s.
I can get TACACS authenticating fine and am able to log on and go into enable mode. Any subsequent commands are then met with 'command authorization failure', including 'show run', 'conf t' and even 'exit'!
My ASA5510 config has not changed, other than to define the new AAA server, which leads me to think its something to do with how I have the ACS user profile set up. I have configured the ACS5.1 device administration Shell Profile to have the maximum privilege level (15) and the command set I'm using has the box checked 'permit any command that is not in the table below'.
I am trying to secure changes to switches using ACS 5.3 and allowing our technicians to only change the vlan for user ports on the switches. How can I use regular expressions to filter out the 1/1/# ports so that those ports cannot be accessed in config mode? If I allow the following, it allows access to all interfaces with 'gi' in them.
I have everything working on a new 5.2 ACS but:I can only make a command set that permits things and denies all.I thought with the check box. Permit any command that is not in the table below" one could allow all and specifically deny commands.and that would allow the user to do all commands except for conf and set. But it doesn't seem to adminstratively block it, it allows them to still "conf" for instance.
Then it works as expected, it allows the commands that are permitted and denying all unspecified commands.I know I am in the right command set because the changes I make are reflected immediately.Can someone test the "Permit any command that is not in the table below' and tell me if it works? I can make it work with the unchecked box, sure, but it would be nice to get it to work.
I'm trying to configure an ASA5510 with release 9.1(1) in order to authenticate VPN AnyConnect users through LDAP. In a first step the logs shiw me this kind of error:
[-2147483632] Session Start [-2147483632] New request Session, context 0xadf415d4, reqType = Authentication [-2147483632] Fiber started
I have setup a Cisco Aironet 1040 to connect to our Radius server which I have also configured.
I can successfully connect up any Iphone or Ipad but I cannot get any laptop to connect.
I have attached the logs showing the Iphone Successfully logging in and the Laptop Failing. Every single failure in the Event log for NPS comes up with
Network Policy Server denied access to a user. Contact the Network Policy Server administrator for more information.
I have implemented a Guest WLAN solution as per the recommended design from Cisco. We have two internal WiSM2 controllers providing services for Internal secure SSIDs. Both these controllers are members of a Mobility and RF management group.
Two 5508 controllers have been installed in our DMZ for resilience and have been placed into a separate Mobility group. All controllers (internal and external) have been linked together as mobility neighbours in a full mesh and a new SSID for Web Guest traffic has been anchored to the controllers in the DMZ.
Web page authentication works perfectly fine, but I cannot for the life of me get the MAC filtering override to work, i.e. if a MAC address is present, do not redirect to the splash page for web auth. I know I can get around this by just creating two separate SSIDs. But the business is used to just having the one SSID for all guest traffic. Is this a known limitation when anchoring SSIDs to controllers in the DMZ ?

I have an ACS 5.3 cluster, that is configured to use AD. There are a few wireless devices, and monitoring tools that do not have AD accounts. I would like to configure ACS to first check AD for the user authentication, and if that fails to roll over to the local (Internal Users) identity source where I can define these user accounts.
It seems that when the authentication hits the initial Identity Policy rule, it never moves onto the next one if the first fails.
Attached are screen shots that show how i'm configured for the test, i have a local user defined and I'm trying to log into the firewalls.
- Identity Definition : Screen shot of the main ACS definition for the rule i'm testing that's not working - Identity Rule 1 : The configuration of rule 1 that if it fails i need it to move onto rule 2. - Log Output : Screen shot for one of the failed attempts from the ACS View Log server.
Reason I need to configure it this way is:
- Wireless users authenticate to wireless using AD user accounts. Some hand held scanners do not support that and will need to authenticate using the MAC address. - Authentication to Network devices for managment uses AD accounts. We have some monitoring tools that do not have AD accounts, and will need to be able to log into Network devices to issue some commands (Examples: Cisco Prime LMS and NCS, Infoblox NetMRI).
I managed to connect acs5.1 to the AD , user's will be able to get authenticated against the AD when the state is shown "CONNECTED'. This will work ok for a day or so and goes into a 'DISCONNECTED' state , users will no more be able to authenticate . Is this a known error , or is this an error from the microsoft ws2k3 server side ?
I know ACS 5 lacks the IP Pools of earlier ACS versions. I'm looking at a 4 to 5 migration and was thinking of just configuring the IP Pools on the router ("ip pool local" etc) and sending back a RADIUS Cisco Attribute pair with the name of the pool. (Seemed like a neat fix, needs no extra kit, etc.)
I could have sworn that attribute pair existed... but I can't find it in ACS5! What's it's name?! Where is it!? Or have I gone mad!? (And, if I have gone mad, how would you go about fixing it?)
In ACS 5.3 radius authentication report I want to show the called-station-id attribute. (this was appearning on failed and passed auth in ACS 4.2). The value of called-station-id appears in the details. However, I want it to appear as a column with the report.
I want to export the ACS local user's records.Then import to other ACS5.3 server.But the export file not the user's password record.I cannot import it well....
we are moving network devices (200+) authentication/authorization/accounting to new ACS5.2, is there any easy way to copy/sync all those AAA clients configuration to another ACS5.2 server? I don't need other configuration to be synced/copied to another ACS5.2 server
I'm trying to dynamically assign IP address for VPN users from AD (without IAS service). I know that there is a restriction that "Dial-in users are not supported by AD in ACS (note in "acsuserguide51") but Im not exacly sure what can and can't do with it. In "Authorization Profiles" in RADIUS Attributes tab I try to mannually add specific Attribute (Framed-IP-Address).
I have no problem (everything works just fine) with static address assignment in a way as below:
AD is already integrated with ACS and I've managed to download Directory attributes especially msRADIUSFramedIPAddress
When I change "Attribute Value" from static to dynamic type I see the option to select AD (but "Select" which should list all available attributes is empty)
I know that I can do it directly (ASA <-> AD attribute mapping) but I want ACS to do it
Im trying to configure a 7204 for radius login authentication, although the router is also configured with radius for VPN access. How can I configure it for both using 2 different raidus servers? the login via radius is working fine on another router, although that one is not doing VPN access so there's no conflict.
My config:
aaa group server radius RADIUS_AUTH server x.x.3.11 auth-port 1645 acct-port 1646 aaa authentication login networkaccess group radius local
[Code]....
For some reason, this does not work. I cannot access the router and authenticate via x.x.3.11 radius server. I think there's a conflict between the VPN and the login authentication but im unsure how to resolve this.
We are trying to make a restore from the backup done on ACS version 5.1 to a new appliance running ACS5.2 Before doing it I found this note in Cisco ACS user guide:
Note: You cannot back up data from an earlier version of ACS and restore it to a later version. Backup and restore must be performed on the same version of ACS. If you need the data on a different version of the ACS, you can perform an upgrade after you restore the data. Refer to the Installation and Setup Guide for Cisco Secure Access Control System 5.1 for more information on upgrading ACS to later versions.
How should I understand it? This note has conflicting statements. We can't restore to a later version but if you need data on a different version of ACS you can perform an upgrade AFTER YOU RESTORE the data. Doesn't it mean that the restore will still work? How would I do the upgrade to version 5.2 or even version 5.3 that was announced to be released very soon? I didn't find anything on the software upgrade in ACS5.1 guide.
I am using ACS5.2 I want user to access the device with all necessary command like show run/ver/int/log… I try to set user privilege using Shell from 1 to 10 but show run doesn't work.
I configured an ip pool on VPN 3000 concetnrator. i wanted to an attribute to use on the nework access profile on the acs 5.3. i was advised to use pool name. However, we don't have pool name attribute on VPN concentrator. only, IP range and subnet mask. how do i refer an IP pool on VPN concentrator in ACS5.3? is there another attribute I can use on ACS5.3 to invoke a pool on CVPN3000, like ip range...?
I had a problem about authentication use AD group member. Below webiside is the way I config on ACS.

I'm using ACS 5.1.0.44 and this version has a bug , ACS cannot read AD group. I have to add it manually . After I change the access policy from Internal user to AD1. I can use anyone AD ID to pass authenticaiton. I finished all config from the website had same result.
I checked the access polices -- default device admin -- authorization , the new rules I created had no hit count. How can I make sure that I make a right config ?
We plan to use machine certificates on our notebooks with Windows Vista. Our authenticating server is Cisco ACS 5.1. To access the wireless network we want to use the machine certificate of the notebook and a verification of the corresponding computer account in the Active Directory. What authentication method is the best to check the machine certificate and if in the Active Directory exist the enabled corresponding computer account ? How to configure the ACS and the notebook to use it like described ?
I am using Cisco ACS5.3 to authenticate users (using radius) for a cisco ASA firewall for both WebVPN and IPSEC client connections. I have been able to do this successfully. However I need to be able to deply Cisco vendor specific attributes (VSA) for both IPSEC and WebVPN sessions using authorisation profiles. Ideally I don't want to have to combine the attributes required for both services in the same authorisation profile, as I will have to produce alot of different profiles for the different combinations.
The only way I can see that you could possibilly do this is by having service selection rules that can differentiate between WebVPN and IPSEC Radius authentication requests. I have experimented inbound VSA's without success. Is this possible?
1. Try to authenticate user in external database1 (radius) 2. When external database1 returns FAIL (because of bad password) ACS5 should try to authenticate user in another external database2 (radius)
I am having difficulties implementing Mac-auth on selected ports between an HP ProCurve 2510 and Cisco ACS 5.3.The 802.1x works just fine, but for selected ports I need to implement port-access with MAC-based authentication instead of regular 802.1X (yeah, I know, but this line of ProCurve switches only support one auth-mechanism per port!).The switch successfully forwards interesting MAC-auth requests for authentication to the ACS with CHAP/MD5, but the ACS reports this:
Logged At: April 16,2012 1:20:48.080 PM RADIUS Status: Authentication failed : 22056 Subject not found in the applicable identity store(s). NAS Failure: Username: 002655886b3d MAC/IP Address: 00-26-55-88-6b-3d Network Device:
[code].....
The ACS is configured to use the Internal Hosts database, where the client computer is configured like this;MAC-address: 00-26-55-88-6B-3D
We are deploying ACS 5.2 to replace our ACS 4.2 in production. I have two wireless networks setup as WPA2-Enterprise. One points at the ACS 4.2 and the other at the ACS 5.2. Both use the same SSL certificate with the same CN. Both authenticate Windows 7 clients. However, Windows 8 CP will only authenticate to the ACS 4.2 and not to ACS 5.2. The error it gives is:
11051 Radius packet contains invalid state attribute
It also shows no authentication method (most of the time).
Occasionally, I get a request that actually shows an authentication method of PEAP (EAP-MSCHAPv2) which is what it should be. On those requests, I get error:
24444 Active Directory operation has failed because of an unspecified error in the ACS.
Both ACs 4.2 and ACS 5.2 are pointed at the same Windows AD source.
Running ACS 5.1 appliance, and am seeing slow repsonse on TACACS authentications due to the ACS trying to reach overseas AD servers and failing. Is there any way to configure a /etc/host/ file locally on the ACS in order to force the appliance to use specific AD servers for authentication? As I understand the process currently, the ACS appliance will query the top-level domain and get a list of all the AD servers in DNS. In my case, this would include the AD servers overseas that we do not want to use.
Our customer has the business needs to authenticate remote users against AD with empty password. I've seen ACS5.1 release note where mentioned about resolved issue: #CSCte72751 #ACS 5.1 drops authentication with empty password.
I tried to authenticate dial-in users through Tacacs and Radius against AD with empty password but without success. ACS points to wrong AD password. Is it possible to authneticate remote users with empty password?
About to apply a patch for the first time on the ACS 5.3 tonight. Ihave tftp'd it onto a directory i have created on the server. However my support hints i may havre to rename the file ? copy the latest patch file you got from Cisco – you may need to rename as gpg) Current filename is 5-3-0-40-7.tar.tar
So would i need to rename this as 5-3-0-40-7.tar.gpz . If so i will rename it on my pc and redownload it on tftp
I have a Cisco ACS 5.1 virtual appliance which has been working fine, I have however just discovered that it is now unable to provide me with any logs. TACACS authentication is still working without any issues, the only problem I have is viewing the logs.
My question is on ASA and ACS5.2 users.Have my ASA SSL VPN and IPSEC VPN, the my ACS5.2 many users, for example, wireless user.I would now like to establish an independent user group, only the VPN user name and password, while both the ASA VPN can only allow users in this independent group of ACS5.2 VPN login, how to configure?
