Cisco AAA/Identity/Nac :: MS-CHAPv2 Attribute Error In ASA Querying AD Via ACS 5.2
Jun 28, 2011
We have just set up a Secure ACS 5.2 VM to provide authentication for Anyconnect VPN clients. The clients connect to an ASA 5520, which queries the ACS, which in turn queries Active Directory directly. All seemed to work OK, but I noticed it was using PAP. Following some docs, MS-CHAPv2 was enabled via the "Password-management" command. This broke the configuration and the error on the ACS was:
11309 Incorrect RADIUS MS-CHAP v2 attribute Some references suggest that the ASA and ACS should talk MSCHAPv2 without additional config, so I guess it must be the ASA config for the tunnel-group. There are additional secondary authentication and authorisation pages on ASDM, that I suspect might be necessary to use mschap.

I'm authenticating users against Active Directory and want to also check additionals attributes from LDAP. In ACS 5.3. it was possible to set this up via External Identity Sequence, but in ISE I don't see this possibility. I can set sequence only for authentication, but not for additional attribute retrieval.
When I set a condition in a policy that an LDAP attribute must match with some value, the attribute is not retrieved and autorization ends on default Deny Access.

I'm using Cisco ACS 3.3 for RADIUS. How to do I make Vendor-Specific attribute available? (Attribute number 26, format: OctetString) The online help makes reference to it, but does not tell you how to make it available.

ACS 5.3 always sends the class=cacs:xyz attribute in an authentication response. How can I suppress that behaviour? The Cisco Email Security Appliance doesn't support multiple class attributes (defect 49096) and even treats guest users as administrators.

I have a working ASA 5505 that is used for remote access. It authenticates users via RADIUS (Microsoft AD using two IAS servers), it also authorises users via LDAP and it does some LDAP attribute mapping to get group membership for DAP. This is all working fine however recently I enabled IPv6 to do some testing. I have a /126 subnet on the Inside interface (maps to its equivalent /30 IPv4 subnet) and OSPFv3 running so the ASA has visibility of the internal IPv6 networks. DNS client is enabled in the ASA and all the authentication servers are entered as hostnames. The two RADIUS servers only have A records and the two LDAP servers (Windows DC's) have both A and AAAA records. My plan was to begin test IPv6 on the AnyConnect VPN clients (once I was happy the ASA was working fine with IPv6).
When I initially enabled IPv6 everything continued to work as before, however I had to reboot the ASA today and after it all came back up authorisation stopped working. I did a bit of troubleshooting and the ASA is complaining of not being able to resolve the addresses of the two LDAP servers. From the CLI I can ping the hostnames and the LDAP servers resolve to IPv6 addresses and the RADIUS servers resolve to IPv4 addresses. When I issue the command 'show aaa-server LDAP' (LDAP is the name of the group) I see the servers listed but the address displays 0.0.0.0:
Prior to the reboot both the LDAP servers were showing thier addresses (IPv4) correctly. I can workaround it by disabling IPv6 on the ASA, letting it lookup the (IPv4) addresses of the LDAP servers (so they appear in the 'Server Address:' field above) and then re-enabling IPv6. Strangely deleting and re-adding the servers just with their IPv4 addresses also fails but I haven't fully tested this. I don't know but I think I would have the same behaviour if the RADIUS servers also had AAAA records.
I assume when IPv6 is enabled on the ASA it will perform AAAA lookups as well as A lookups but the LDAP client cannot use IPv6? Just guessing at the moment as I haven't managed to get a LAN capture. [code]

I have two ACS v 5.2 (primary and secundary) and some users are in the internal stor and the others are in the AD.The local site topology is like this:
PC - AP - WLC - ACS - AD
Authentication method is PEAP(EAP-MSCHAPv2) and all user have the certificate company installed. The OS in the client users is Windows 7.Users was working fine but some users reports intranet disconnections. I see in the ACS log many "22056 Subject not found in the applicable identity store(s)." and "24415 User authentication against Active Directory failed since user's account is locked out" alarms.I believed it was because user wasn´t in the AD data base, but some times the same user is authenticated successfull and other i see the "22056...." or "24415...." alarms.
I switched the role for ACS primary to works as secundary and we see the same alarms.

I have a brand new ACS version 5.2. Everything is working fine. I go to cisco website and download the following packages:5-2-0-26-8.tar.gpg
From there, I ssh into the ACS and performed the following: acs patch install 5-2-0-26-8.tar.gpg repos acs-52-patch That works without any issues. My ACS is now upgrade to 5.2.0-26-8 An hour later, when I tried to perform this: acs patch install ACS_5.3.0.40.tar.gz repository Upgrade_to_5.3.0. it is not working. I get this message: Failed to copy file 'ACS_5.3.0.40.tar.gz' from repository Upgrade_to_5.3.0 (Error -306).

I continue to export a Certificate Signing Request for our local CA. They insist they are getting a parsing error (Invalid algorithm specified) when they cut and past or import the file I send them. In fact, they have stated that they have had this error with another Linux-based CSR.
I'm not find this issue prevalent on the Internet, so I wonder is this if a user issue on their behalf or the fact that they are using a Win2003 box as a local CA.
How to get a Cisco ACS ".pem" file signed in a local Win2003 CA or advise to an alternative to configuring 802.1x using EAP-TLS?

I have problem with ACS 5.0 on reporting. On "Monitoring and Report" page in Faverite Reports when i clicking on "Authentications - RADIUS - Today", My browser displays error "Error while reading skin-access.config. Please make sure the file exists and conforms to the schema specified"
I must also mention that I never upgraded the version of ACS from 5.0 also from command line all the acs services are running. It is running on CISCO 1120 Secure Access Controll Server apliance.
My second question is can I upgrade the version of ACS to 5.4 with Cisco Secure ACS 5 Base License?

24016 Looking up user in LDAP Server - testuser
24004 User search finished successfully

24031 Sending request to primary LDAP server
24016 Looking up user in LDAP Server - testuser

24027 Groups search ended with an error
22059 The advanced option that is configured for process failure is used.
22062 The 'Drop' advanced option is configured in case of a failed authentication request.
Some users never get this error, others will get it once in a while and I have one user that gets it every time they try and login.

I am having the Cisco NAC enviroment (Software Version is 4.9.1) and OOB VG.
We are getting the below and attached Error while deploying on some machines.
"Invalid switch configuration-OOB Error:OOB client "mac/ip" not found."
Some users on same switches are working fine but some are not....
What would be the possibilities and any work around? other than keeping the port shudown for long time means that atleast 10 - 20 secs or more or a PC restart. Customer is not feeling comfortable with the current situation.

I'm configuring a Cisco 7206 NPE-G2 as B-RAS for PPPoE over a Gigabit Ethernet interface. Everything is OK but I'm having problems when i try to pass the framed-route attribute from the RADIUS to assign a /29 sub net to a PPPoE client, the 7206 seems to skip it and no route is installed in the routing table.
This is the configuration:
upgrade fpd auto
version 15.0
service timestamps debug datetime msec
service timestamps log datetime msec
service password-encryption
[code]......
I tried also with Cisco-AVpair ip:route with the same results.
