WLC 5508 + NPS MS-CHAP v2 Auth problems

Hi,
I am having a lot of trouble trying to set up a Cisco WLC 5508 to use NPS on Windows Server 2008 as it's authentication.
When a client attempts to connect to the WLAN, the authentication is denied on Windows 7/Vista/XP, however, on Mac/iOS clients, it asks to accept the certificate (this is a public cert, issued by Entrust - however, it is a wildcard cert..), but then it will connect.
So I have two questions:
1/ Why won't the windows clients authenticate? If I set up the WLAN profile on the windows machine, and I deselect "Validate server certificate", then they connect just fine....
2/ Is it possible to make it so the user is not prompted to accept the certificate? Why can't this certificate be validated locally by the client?
Thanks,
Josh

Looks like it might have been an issue with that certificate, I don't know.
Either it didn't like the wildcard, or it didn't like the intermediate/root CA.
I downloaded a Comodo Trial SSL and plugged that in - works like a charm now!

Upgrade WLC 5508 to 7.4.121.0 problem

After I upgraded WLC 5508 from 7.2.111.3 to 7.4.121.0, all 3602i APs don't associate with the controller. All APs were working/associating with controller on 7.2.111.3 at same setting. IP address of APs are setup as DHCP.
The error message is "AP couldn't get IP address".
Any one has this type of problem when you upgrade WLC 5508 from 7.2.111.3 to 7.4.121.0.
Thanks,

Hi,
This doesn't look like software issue.
You have to check why the APs are not able to get ip address. Try connecting a PC to a swtich port where one of these APs are connected and see if you are able to get IP on PC.
Also check if the DHCP server is reachable and if there are IP address in the pool assigned for APs.
HTH,

WLC 5508 LDAP Windows 2008 Server - auth based on AD groups

hi NG,
i'm trying to web-authenticate my Wifi user of an WLC 5508 against LDAP.
Thereby i'm trying to autenticate all users within a GROUP, not an OU within the MS Active Directory based upon an Windows 2008 Server.
I can authenticate against a user, witch is beeing put into an OU, according to examples based here: https://www.cisco.com/en/US/products/ps6366/prod_configuration_examples_list.html
Checking based upon Users within OUs works fine.
But i have not got all of those users wihin one single OU!
Need help for following:    LDAP-Auth based on AD Groups:
Using:
MS-Domain:                          MY-DOMAIN.CH
AD-GROUP:                          VPN-USERS
AD-Structure:
MY-DOMAIN.CH
|
GROUPS
        |
    Administrative Groups
                      |
                 VPN-USERS
                          (-> Member of this Groups (Wireless1, Wirless2, ...)
Server Adress:               IP.IP.IP.IP
Port:                                 389
Enable Server Stats      YES
Simple Bind                    Authenticated
Bind Username              LDAP-USER
Bind Password               supersecret
Bind Passw. confirm      supersecret
User Base DN:               ?-1-?
User Attribute:                ?-2-?
User Object Type:          Person
Server Timeout               2
What happens for instance, if i put a GROUP within a GROUP regarding the LDAP Authentication.
I guess i have to authenticate against the "upper" GROUP, or do i have to create an entry on the WLC for every GROUP i'm questoning?
Could some one provide my with an example, since i have not found documentation regarding this topic.
Thank you.

Hi,
User Base DN : this is in case you want to restrict the search area. If you put "dc=mydomain,dc=CH", you will search your whole AD. Depending on the size, it can be slow ...
Remember that the User Base DN is also used for the admin user.
In conclusion, User Base DN should be the most restrictive path that leads to both the admins and the users you want to authenticate.
Example :
OU=Employees,OU=Humans,DC=Mydomain,DC=CH
This would prevent to search in machines or any assets. This implies that the admin you bind with is an employee and you are only authenticating employees. You can have any number of OUs under employees, it doesn't matter
Attribute : This is the object attribute that the WLC uses to compare with the user name. In general, you would go with sAMAccountName in AD. CN would be another common example for LDAP databases.
If what you are looking for is to restrict access and only authenticate people who belong to a certain group. Then you need a radius server like ACS.
That server will be able to make selections and check the "memberOf" attribute to make sure it is in a certain group.

Cisco WLC 5508 - NPS Radius

Cisco WLC 5508
Software Version: 7.4.100.0
Windows Server 2008R2
I've got everything setup on the Windows Server 2008 side of things (certificates, radius clients, etc)
I added the radius server on the WLC, and configured a new WLAN to use it.
Both are on the same subnet.
When trying to conect to the WLAN it kept failing. I installed wireshark on the server to monitor the radius traffic, and to my surprise there was no radius traffic showing up on the server. The radius statistics on the WLC are at 0 as well, so it's like the WLC isn't even attempting Radius.
I reverified that the server was enabled on both the security tab and the WLAN itself on the WLC. Rebooted the controller and the server, all to no avail. I used a radius test client, and can successfully send radius commands to the server using that utility.
Frustrated, I just kept trying to reconnect on my wireless device, and after about the 15th try, finally I saw radius activity on wireshark. It rejected my access, but at least I saw activity. It also registerd radius statistcs on the WLC as well.
So now if I keep trying to connect repeatedly, about every dozen or so times the WLC actually will send a radius request to the server.
What in the world is going on here?

I do have local management users on the controller.
Some hours later I added the option of authenticating management users, for the NPS server. Then logged inn to the management GUI using NPS radius, worked just fine.
However, these commands have been useful to me several times, to make sure unsuccessful requests appear in the Windows Event log:
auditpol /get /subcategory:"Network Policy Server"
If it shows ‘No auditing’ or just "Success", you can run this command to enable it:
auditpol /set /subcategory:"Network Policy Server" /success:enable /failure:enable
So now I know that the NPS radius server works, for management access. I will go to the customer's site some other day to test it for 802.1x authentication. If not, I'll do some debugging to decide wihich to blame - the WLC or NPS.

WLC 5508 - wlan stability problems

EAP-TLS with WLC 5508, Microsoft NPS and custom EKU OID´s

We are trying to implement EAP-TLS with client certificates that have a custom EKU OID to distinguish the WLAN clients. The Microsoft Press Book
Windows Server 2008 PKI and Certificate Security gives an example on how to configure a policy in NPS that matches specific EKU OID´s. At the moment we have two policies that have an allowed-certificate-oid configured that matches the OID´s in our certificates, but our setup is not working as expected. Authentications will only be successful, if the client authenticates with the certificate that is matched by the first policy rule.
For example:
Policy 1: allowed-certificate-OID --> corporate
Policy 2: allowed-certificate-OID --> private
Client authenticates with EKU corporate --> success
Client authenticates with EKU private --> reject
My expectation was, that if Policy 1 will not match the NPS goes over to Policy 2 and tries to authenticate the client.
Has anyone a simmilar setup or can help to figure out what is going wrong?
We have a WLC 5508 with Software Version 7.4.100.0 and a NPS on a Windows Server 2008 R2
regards
Fabian

The policy rejects and the NPS goes to the next policy, only if the user does not belong to the configured group.
This means I need to have one AD group per application policy, but that will not solve my problem. A user could belong to more than one group, depending on how many devices he/she has. It will work with one group only for each user, because the first policy that matches a AD group, the user belongs to, could have a OID that is not in the certificate. This would cause a recejct with reason code 73:
The purposes that are configured in the Application Policies extensions, also called Enhanced Key Usage (EKU) extensions, section of the user or computer certificate are not valid or are missing. The user or computer certificate must be configured with the Client Authentication purpose in Application Policies extensions. The object identifier for Client Authentication is 1.3.6.1.5.5.7.3.2.
The certificate does include this OID but not the custom EKU.

WLC 5508 Web Auth Splash Page: Is it possible to place a download?

Hi,
I know it is possible to create custom web auth splash pages on the WLC 5508. Is it also possible to embedd a small document (less than 1MB) that users can download directly from the controller? I need this for providing the terms of use for the Guest WLAN.
Thanks
Michael

It could be done, but you will want to stay within the limits of the WebAuth bundle size (~ <10MB I believe). This shouldn't be a problem considering a .doc size, but I have to ask the same question. Why would you want to do this as opposed to just putting your terms of use inline to the page as just text/html? Maybe there is a good reason, but I can't really think of any scenario. Feel free to elaborate.

WLC 5508 with AD, NPS but without GPO, how?

Hi,
I didn't found anything related to what I'm trying to do so I though I would create a new discussion...
I would like to setup a new WLAN and to be able to connect, a user will have to enter his username/password that will be confirmed using NPS and Active Directory. The problem is, I don't want to use a GPO, I would like to only verify if the user is a member of a AD group, let's say "wlan_access".
I don't want to install anything ( certificate, GPO, creating a WLAN configuration ) on the user's PC/laptop, only AD validation using NPS as a Radius server.
If a user is part of that AD group, after he enter his credential he will have access to that WLAN.
Is it possible to setup that? How should I configured the WLAN in my WLC 5508 ( running 7.2.110.0 )? How should I configure NPS ( Windows 2008 R2 Enterprise )?
Thanks a lot for your help and answers.
Guillaume

Hi guys,
With the info Stephen Rodriguez gave, it looks like I won't be able to do what we want without doing config on the user's devices ( laptop, ipad, etc.. ).
@Joseph Vasanth Louis Yes the message is from the event viewer of the NPS server. In the connection request policies, there's not much config, I let the option "Authentication Methods" in the tab Settings uncheck, so it won't override the settings in the Network Policies.
I though it was possible to have authentication using NPS and Active Directoy without installing anything on the user's devices and still having a secured wireless network ( not like a hotspot ).
The solution I think is the most workable is with the PEAP or PSK, with a certificate but even that...the user will have to create the WLAN profil on his laptop, so I'm not sure we want to go that way. I'll check for the PSK option, to see if the "Web Authentication" could be done using NPS.
Thanks guys for all your time and help. I'll continue my tests and keep you posted.

Integration between WLC 5508 and Microsoft NPS 2008

Hi guys,
Any of you, have working guidance for WLC 5508 and Microsoft NPS 2008 integration?
I managed to configure Wireless 802.1x feature (PEAP) but it failed. I'm running software ver. 7.0.116.0.
Is there any bug related 802.1x on this software version?
thanks in advance.

shendy

Hi Shendy,
I am not aware about any bug related to this. I think you better check all configuration and make sure it is fine.
Logs from NPS and WLC (and possibly from the supplicant) may guide you where the problem resides.
What does the NPS logs tell about the reason of the authentication failure?
What does the WLC logs say about the failure (check show msglog and show traplog).
- Make sure the Radius server added correctly with correct IP and correct shared secret on WLC.
- Make sure that the radius is configured correctly to allow PEAP-MSCHAPv2.
- Make sure WLC is added successfully to WLC with correct IP address and correct shared secret.
- Make sure the clients are correctly configured and the server's (NPS) certificate is trusted on the clients.

I already go to this link to check the Description of errors-
http://www.cisco.com/en/US/docs/wireless/controller/message/guide/msgs4.html#wp1000139
Appreciate all feedback. Thank you.

Hi Ruben,
a) After successful dot1x authentication, session keys are derived from pairwise master key.
b) When the AP transmits a key to a station by default, it expects a response back within a set timeframe.
c) If the station does not respond, the AP increments the counter and retransmits the key.
d) If the AP receives a response to first message just after the retransmission of the key, a mismatch occurs in the counter.
This in most of the cases will be a client driver problem.
Solution :
1) try to increase the EAPOL-Key Timeout ( config advanced eap ).
2) Upgrade the client driver.

I agree go to version 7.4.121.0 I has some strange issues on prior releases. Personally I am running 7.6.120.0 right now but that's mainly due to support for the 3702 access points.

that's a good guide just to double check yourself just in case. -

WLC 5508 WPA Authentication Problems

Hello,
We have a WLC 5508 with 7.4.100.0 Firmware.
We are using 1141 and 1142 APs and we are having authentication problems with clients that are connecting to our WLAN with WPA+AES autentication. The clients receive in her laptop a password error, and we receive the following log in wlc:
Client Excluded: MACAddress:f8:f1:eb:dd:ff:cd Base Radio MAC :08:ad:dd:76:4d:30 Slot: 0 User Name: unknown Ip Address: unknown Reason:802.1x Authentication failed 3 times. ReasonCode: 4
The strange thing is that the problem is solved restarting the Access-points.
Anyone had this problem previusly?
Thanks in advance.

I made the configuration using the Cisco Recommended settings, the strange thing its that the users connect normally, until they starts with authentication problems. I restart the access points and the problem its solved.
Cisco Recommended and not recommended Authentication Settings
Security encryption settings need to be identical for WPA and WPA2 for TKIP and AES as shown in this image:

Problem uploading SSL certificat on a WLC 5508

Hello,
I'm trying to upload a SSL-certificate (RSA:2048) on a WLC 5508 via the "Management->HTTP-HTTPS" - Tab and get the following problem :
*TransferTask: Jul 18 16:36:14.487: %UPDATE-3-CERT_INST_FAIL: updcode.c:1276 Failed to install Webauth certificate. rc = 1
*TransferTask: Jul 18 16:36:14.487: %SSHPM-3-KEYED_PEM_DECODE_FAILED: sshpmcert.c:4028 Cannot PEM decode private key
I've generated it using the following commands:
# openssl pkcs12 -export -in my.crt -inkey my.key -certfile my.ca-bundle -out CA.pfx
# openssl pkcs12 -in CA.pfx -nodes -out CA.pem
But it doesn't work...
Does anyone have an idea?
Best regards,
Eric

Hello Eric,
I'm facing the same problem, when trying to upload a chained SSL certificate (2048bits) to the wlc version 7.0.116.0
Did you use an unchained certificate and what size is your cert?
According to a Cisco document, for controllers version 5.1.151.0 and later, only unchained certificates are supported for the management certificate.
I'm just wondering, if this limitation still applies to the newer versions.

Oliver

RF Grouping problem WLC 5508

Hi,
We have a problem regarding RF Grouping between two WLC 5508.
The two controllers have the same RF Group name,RF Grouping is enabled,they belong to the same mobility group,their management IP
address is on the same subnet, they ping each other but they don't elect a Group Leader. Each one
elects itself as the Group Leader.
We have tried to place 2 APs,each belonging to different controller, close one to the other but nothing changed.
Any help would be much appreciated.

Hi Nicolas,
Because we have an almost live network, we wouldn't like to go public with our configurations. Is there any other way we can send them to you?
Thanks in advance,
Theofilos
