Cisco AAA/Identity/Nac :: ACS5.3 - Configuring Multiple Identity Sources
Aug 28, 2012
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).

Currently on ACS 5.2 and our MS Active Directory is migrating to a completely new domain. There will be a two way trust between them for the 24 month migration period. How best to configure ACS connect to both domains?

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 understand that Cisco Secure ACS 5.3 supports the integration with existing external identity repositories such as Windows Active Directory and LDAP servers. In fact, in my environment, my ACS 5.3 is now integrated with AD and RSA.My question here is can Cisco Secure ACS 5.3 integrate with "multiple" WIndows AD, LDAP, RSA Server etc.? if yes, is there a Cisco document stating this? The keyword here is multipple.

I am trying to setup PEAP authentication for wireless users but I got stuck at place where I have single ssid and users are store in different identity stores like some will be using their active directory and some are locally created users on ACS. I created separate service for wireless authentication and under that I am unable to create rule to differentiate them with identity stores. any idea how to achieve this.
I tried creating identity selection based on role but it does not work as for protocol like radius.peap,ms-chap ACS does not look for another identity store once user not find in an identity stores.

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?)

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'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

Is it possible to create on ACS5 rule which will:
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 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 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'.

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 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.
[URL]
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?

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?

I have ACS4 and i am planning to upgrade to ACS5.I would like to have such a rules:I have user1, one ASA device which is VPN concentrator for remote users.ASA have two different tunnel-groups: one which allow for logging via certificate (with mandatory pki authorization thru ACS) with disabled Xauth,and second tunnel-group with allow login thru typical Xauth with authorization thru ACS which users external database (RSA Tokens).So i have one user1 which can login thru VPN using RSA tokencode or certificate.For example: on phone user1 uses certificate, and on PC station the same user1 uses token password.For tunnel-group with pki authorization ASA checks username in ACS and in typical scenario login="CN from certificate" and password="CN from certificate". So we would need "two credentials" for the user - one for pki authorization, and second one external database (RSA token).Is such scenatio possible under ACS 5 ? where one user uses different credentials based on tunnel-group usage ?

I'm trying to make a redundantish office/datacentre connection on the cheap. At the datacentre, we've got a 7301 (12.2(24)T5) and at the office we've got a Mikrotik RB1200 (5.12).The office router has two ADSL connections to two different ISPs, the datacentre router a single GigE to a colo provider. I'm trying to build an IPSec encrypted IPIP tunnel over each ADSL service to a separate loopback interface on the datacentre router, so I can run OSPF over the top for route exchange. I need to use two different loopbacks on the datacentre router so the office router can have a static route for each out each ISP ADSL. But I'm running into issues making encryption work on two different source addresses.Using the 'crypto map xxx local-address Loopback12' command, I can specify the outbound interface for one of the tunnels just fine, traffic moves as expected - while the other tunnel fails to encrypt. But is there a way of having two peers use two different local addresses, or applying two crypto maps to a single physical interface?

I am trying to configure AAA authentication and authorization with Cisco 3725 (IOS 12.4(17)) for 802.1x and ACS 4.2 with VLAN assignment to my Windows XP client. (trying to assign VLAN 100 in my scenario).When user connects to the Router, it passes the authentication process (EAP-MD5). In my debug i see that Router recieves the Radius Attributes BUT does not apply anything!My running config:
Building configuration...
Current configuration : 1736 bytes
!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec

As a result the vlan-switch data based does not change.

I am struggling with configuring NPS AA for our 3750 array ... authentication and authorization. I tried almost every config i could find online but the most i got out of it is a simple authentication. What i need is quite simple: we have several AD groups.
1- Admin
2- Read only with few privileges for ping, show, trace route and telnet
I need my switches to be able to recognize the groups and assign them the correct priv. But it doesn't seem to be happening. Any clean config for the switch and for NPS ?
