Cisco AAA/Identity/Nac :: ACS 5.1 LDAP Group Search Error?
May 9, 2012
I have a problem where occasionally a user will attempt to login and the LDAP search will find the user but then fail when it does the group search. The error I get is below
22037 Authentication Passed
22023 Proceed to attribute retrieval
24032 Sending request to secondary LDAP server
24016 Looking up user in LDAP Server - testuser
24004 User search finished successfully
24027 Groups search ended with an error
24034 Secondary server failover. Switching to primary server
24031 Sending request to primary LDAP server
24016 Looking up user in LDAP Server - testuser
24004 User search finished successfully
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 have a new Cisco Secure ACS 5.2 on a VM. We want to use it to for administrative access to our Cisco equipment with TACACS+. I am trying to map user permissions to different groups of devices based on active directory group membership, however it is not working.
I am using an LDAP (configured for secure authentication) external identity store. On the directory organization tab, I have confirmed the accuracy of the subject and group search base and the test configuration button shows that it's finding > 100 users and >100 groups.
On the directory groups page I have entered the groups according to the required format. cn=groupname1,ou=groups,dc=abc,dc=com
I have a rule based result selection under group mapping. I have two rules in the format below.
Conditon
LDAP:Externalgroups groupname1
Result
Identitygroup1
I have the default group set to a identity group named other. My problem is, no matter what user attempts to authenticate, the Default rule is applied, and the user is put into the other identity group.This occurs when I log on as a groupname1 user, groupname2 user, or as user that is not a member of either of those groups. LDAP authentication works and the user is able to logon to the device.

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 try to map LDAP Group to ASA Group policy following documentation:
[URL]
This is a config for ASA 8.0. I would have expected it to work on 8.4 as well but I do run into problems. The mapping as shown in LDAP Debug and ASA Log will actually happen but it is overwritten by the "GPnoAccess" Group Policy configured locally in the Tunnel Group. From earlier works with RADIUS I would have expected the user specific Attribute to be "stronger"?
ASA Log:
AAA retrieved user specific group policy (correct Policy) for user = XXX
AAA retrieved default group policy (GPnoAccess) for user = XXX

I am trying to move a device from the Default location to a sub group and get the following message when I try (either with IE or Firefox)
This System Failure occurred: Index : 0, Size: 0. Your changes have not been saved. Click OK to return to the list page.
it also gives me the same error if I try and change the Device type from default to a sub group. I'm sure I could do this previously. The ACS build is (VMWARE install):

There was an error while parsing and rendering the content. (Tried to register widget with id==mseLicenseInfoDialog but that id is already registered) This occurs whichever role you log in as and only happens on teh simple search, when using teh advanced search we do not see it.

I'm currently looking for a solution in order to restrict the modification of the host internal identity store (add or delete MAC host) per group. The default administrator roles does not include "per group restriction". Under the ACS I defined one group per department? My objective it to allow each department to access their ACS MAC database to add or delete MAC addresses as required.
How to restrict internal identity store per group?Do I need to create new roles? and how?I was not able to get an answer from the ACS ADMIN manual.

I am having a problem getting an ASA running 8.3 to authenticate an SSL VPN directly against an LDAP on Windows Server 2003. I have changed the read access on the Active Directory to allow Annonymous to read it. I think I am missing something on the ASA config. I have the Server Group specified with the address of the correct server but nothing else really configured.

know about Domino LDAP ? I would like to integrate this LDAP with Cisco ISE.I try to bind this LDAP but it does not show me anything in "Naming Context". So I cannot choose group to map into ISE.I test this on WLC. It is success to do but cannot make the same thing with Cisco ISE.Is this LDAP supports with Cisco ISE 1.1.1 ?

I have 2 SSIDs on WLCs.I would like to have 1 SSID point to the acs radius using LDAP store and the 2nd SSID point to the acs radius using the host identity store for mac filtering.both scenarios are working, but not together.if I adjust the rule order I can get one SSID, but then the other fails. [code] It seems to me that there should be a simple process to make this happens. I thought if the rule is not matched it would move on to the next rule etc.I might be able to live with first checking ldap and if that fails move on to the local host db, but that seems ineficient. url...

I have an CS-ACS appliance with 5.2.0.0.26.3 version. There is not any direct solution for connect ldap client to server. I have 3 servers that have only ldap and for authentication I can not use radius or Tacacs+. I need a solution for this problem. How can LDAP Client connect to ACS when it has only ldap protocol?

i have a wireless deplyoment with WLC 5508, ACS 5.2 and several AD connected by LDAP. It is required that users are authenticated by certificates additional the user should only get access to the wireless environment when the user is found in a certain security group in the Microsoft AD forrest. The certificate based authentication is working without any problems, except the lookup into the AD isn't working. Here are the Details of the "Evaluting Identity Policy"
Evaluating Identity Policy
15004 Matched rule
22037 Authentication Passed
22023 Proceed to attribute retrieval
24031 Sending request to primary LDAP server
24016 Looking up user in LDAP Server - Alex Dersch
24008 User not found in LDAP Server
22015 Identity sequence continues to the next IDStore
24209 Looking up Host in Internal Hosts IDStore - Alex Dersch
24217 The host is not found in the internal hosts identity store.
22016 Identity sequence completed iterating the IDStores
but the user can access the WLAN just without verifying the user in the AD.
i tried the to enable Binary Comparisation but then the Authentication is not working any more. I get the same Identity Policy result as above.
i configured the Binary Comparisation as below:
I though with the binary comparisation i'll be able to verify the existance and the status of an user in the Active Directory.

Does Cisco Secure ACS 5.3 support LDAP authentication with Apple Mac OS X server? One of our clients require an access control system. The major portion of the network consists of Apple Mac OS X 10.7 (Lion) Server and clients. They were using MAC-address based authentication along with LDAP through Cisco Wireless LAN Controller. But now the number of users has exceeded the maximum number of MAC addresses supported by WLC (2048). Hence we suggested ACS appliance to overcome the limit. My doubt is whether ACS 5.3 appliance can communicate with the Mac server and perform LDAP authentication.

I've set up a ACS 5.1 Server an want to use it with our LDAP System. Therefor, I'm trying to login to a Cisco 1841 by using my LDAP Account, but it dosent work. The ACS seems not to know that it should use LDAP, because I get,"22056 Subject not found in applicable identity stores"LDAP is configured as Identitiy Store, the bind test works successfully and I created a sequence, where LDAP is at first position. What goes wron?? (TATACS for loal ACS Users works)

I am setting up an LDAP identity store over ldaps in ACS 5.1. I specify that the connection uses secure authentication and provide the Root CA certificate. When I hit "Test Bind to Server", I get this error message in a popup window: "Connection test bind Failed :server certificate not found"Is this saying that ACS can't find the CA certificate uploaded, or does it mean the actual certificate presented by my LDAPS server during the bind test?

I am configuring an ASA 5520 for VPN access. Authorization & Authentication use an LDAP server. I have the tunneling configured successfully, and I can access internal resources. What I want to do now is to restrict access to a specific AD Group membership. In the absence of that group membership, a user should not be allowed access to the VPN.
My test VPN client software is Cisco Systems VPN Client Version 5.0.05.0290. The group authentication is configured into a Connection Entry that identifies the Tunnel Group. I think I worded that correctly.
The Software Version on the ASA is 8.3(1).
My current challenge is getting the VPN to stop letting every access request through regardless of group membership.
[URL]
The configuration (AAA LDAP, group policy, and tunnel group) is below.
aaa-server LDAP protocol ldapaaa-server LDAP (inside) host x.x.y.12 server-port 636 ldap-base-dn dc=domain,dc=com ldap-scope subtree ldap-naming-attribute sAMAccountName ldap-login-password ******** ldap-login-dn

I am working on project with Secure ACS 5.2. I am trying to determine the proper External Database to use. LDAP or direct to AD?
Additionally, the Domain that I am connecting to has Multiple sub domains. All of the users are currently in the Sub domains, but will be moving to root domain later. How should I configure the connection, do I need to connec to each sub domain or can I just connect to the root?

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.

Cisco 5508 wireless controllerCisco ACS 5.1LDAP connection I have setup the wireless controller to do RADUIS authentication with the ACS 5.1 using LDAP. The setup is currently working, Brief info below on setup.
I setup the PC client to use WPA2-Enterprise AES and authentication method CISCO PEAP. When I connect to the SSID this will prompt for a username and password. I will enter in my AD details and the ACS with the LDAP connection will authenicate and on the network I go.
Now I want to add machine authentication with CERTIFICATES, each laptop and pc in our network has CA certificates installed.
way that I can add these certificates into the ACS 5.1 so I pretty much want to import them into the ACS. Once they are imported inside I want the ACS to check that the certificates are on the PC and then prompt for the AD username and password, and only once it meets these two conditions it allows the workstation onto the network.So it will be a two form authentication one with certificates and the other ldap.

I'd like to configure wireless access from winXP to authenticate with our corporate Novell LDAP through ACS
Setup:
WinXP SP3 --> WLC 4402 --> ACS 5.2 --> Novell LDAP
1. Our Novell LDAP server uses secure LDAP (port 636) to authentication user.On ACS 5.2, when we configure this option we need to select Root CA. Should the Root CA in ACS must be the same as the LDAP server's? (the LDAP's certificate issuer)
2. What kind of authentication that this setup supports? Does it support PEAP/MSCHAPv2 as in Windows Zero Configuration or it only supports PEAP-GTC, EAP-FAST, EAP-TLS (which means I have to use Intel Proset/Wireless software to configure).

I have 2 ASA 5520 (v. 8.21) in a active/standby fail over configuration.
VPN users are autenticated against the MS-AD through LDAP. For the most part this works well. Occasionally I'm having problems with new users in the AD. If I run a test I keep getting "User was not found". This can happen days after the account was created still. In some cases it never seems to work. The accounts I create exists on the same OU level as all the other accounts that are working.

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'm trying to configure an ASA to communicate with an AD environment that is only using LDAP Secure (LDAPS). I've configured authentication to ASA's with LDAP lots of times, though never with LDAPS.
Presumably there is a procedure to install a certificate in the same way as an RSA sig in VPN.
