• EAP-FAST EAP and PEAP authentication configuration

  Hello world

  I'm pretty well EAP works, however with the help of LEAP
  When I get to PEAP and EAP-FAST, I can't make it work

  What am I missing, I don't know that EAP-FAST and PEAP require certificates. However, how to configure their client side?
  Hope you guys can help me on this point, stuck on this part xD

  First of all I would make that PEAP or FAST is configured correctly. Debugs them when test pay close attention to the newspapers on the WLC or do what is necessary to solve the problems.

  Good read on local eap...

• Remove the ISE server certificate EAP

  I installed the GoDaddy server certificates on all my 1.1.1 ISE nodes, but customers are still getting the error and accept certificates.  I would just remove EAP certificate and not use any certificate for EAP.

  Explain the problem more in detail. You try to use the comments or 802. 1 x. There are many protocols of authentication you want to use EAP. TLS and PEAP require the use of the cert. What you are trying to accomplish and what are the issues?

• vWLC 802.1 x NPS authentication fails

  Hi guys,.

  I hope someone can help me with the following problem, I am confronted with...

  I have a vWLC 7.3 deployed in our HQ site running.

  At Headquarters, we have a deployed W2k8 R2 NPS to works very well for VPN, router and switch authentication

  In a few remote branch offices that are connected to HQ on DMVPN, we have a couple of 3500 flexconnect with local switching mode.

  These AP register very well through the VPN link to the vWLC.

  We have deployed several SSID that is related to groups of AP.

  All SSIDS that use WPA2 with PSK works very well

  Failure of all SSIDS that use WPA2 with 802. 1 x

  The security settings for the default SSID are:

  Policy of WPA2

  WPA2 AES encryption

  Human key 802. 1 x

  AAA server is pointing to the NPS for Auth and accounting right

  Ray crush IF is disabled

  The parameters of the NPS are:

  Conditions:

  Group Win: DOMAIN\Groupxx

  NAS Port Type: Wireless - IEEE 802.11

  Parameters:

  EAP Conf: configured

  Access Perm: granted

  The EAP method: MS PEAP

  AUTH method: EAP

  NAP enforcement: allows full access

  Update not complient: true

  Type of service: Login

  When a laptop (Mac os 10.8) attempts to connect to an SSID 802.1 x it requests a username and passwd.

  Domain\user using + passwd the client tries to authenticate to a couple of times and fails

  On the vWLC I see trap:

  AAA for UserName authentication failure: user user Type: USER WLAN

  I see to the NPS:

  Access denied to user network policy server.

  Contact the server administrator to strategy network for more information.

  User:

  Reason: An error occurred when using the NPS of the EAP (Extensible Authentication) protocol server. Check the logs for errors of the EAP EAP.

  I hope someone can point me in the right direction.

  See you soon,.

  EAP-PEAP requires a certificate on the side server.

  This certificate is used to construct the SSL tunnel.

  Could please check if the server certificate is installed and valid.

  If the certicate on the NPS is installed properly, you must activate the following debugging

  Debug dot1x aaa

  Debug dot1x events

  Debug dot1x packages

  Use a client to connect to the 802. 1 x active SSID.

  Send debug logs.

  Thank you

• PEAP EAP/TLS, PORTEGE with WinXP sp2 Tablet Edition problem

  We have: Rev AiroNet350 Cisco with WPA - EAP: Freeradius with EAP/TLS and PEAP, tablet PC PORTEGE with WinXP sp2 configuration.

  This problem discribed in http://wiki.freeradius.org/index.php/FAQ#PEAP_Doesn.27t_Work
  Perhaps to solve this problem we need a fix (http://support.microsoft.com/kb/885453/en-us), but microsoft support said to contact the laptop manufacturer.
  Can someone help me with this problem?

  Hmmm I m not an expert in this area, but it seems that the MS OS update is necessary. (I hope)
  The preinstalled Windows operating system is a simple OEM version and generally all updates should be possible. However, if MS guys told you to communicate with the manufacture of the laptop, you can contact the maintainer authorized Toshiba in your country for details.

  But I studied a bit on the net and found this site useful:
  http://SearchNetworking.TechTarget.com/originalContent/0, 289142, sid7_gci945257, 00.html

  1. 802. 1 X is based on communication between your router and a RADIUS authentication server. If you use WEP, WPA or WPA2 with dynamic keys, 802. 1 X debugging following tips may be useful:
  a. reintroduce the same RADIUS secret in your wireless router and the RADIUS server.
  b. configure your RADIUS server to accept the request of the RADIUS of the IP address of your router.
  c. use ping to check the accessibility of router-server.
  d. package watch LAN account to verify that RADIUS and answers queries are fluid.
  e. use an Analyzer like Ethereal Ethernet to watch RADIUS success/failure messages.
  f. for XP SP2, turn on Wzctrace.log by typing "command netsh ras set followed * activated.

  2 if RADIUS is flowing but are rejected requests for access, you may have a problem of incompatibility or credential X Extensible Authentication Protocol (EAP) 802.1. This setting depends on Type EAP. For example, if your RADIUS server requires EAP - TLS, then select 'Card chip or other certificate' of your adapter wireless network properties / authentication Panel. If your RADIUS server requires PEAP, then select "Protected EAP" of the adapter. If your RADIUS server requires EAP-TTLS, then you will need a third-party wireless like AEGIS or in Odyssey client.
  Make sure that this specific EAP properties match for your adapter and the server, including the server CA certificate root trust Server domain name (optional but must match when it is specified) and the customer (EAP-MSCHAPv2, EAP - GTC) authentication method. When you use PEAP, use the control panel to 'Configure' CHAP to prevent Windows from automatically re-use of your connection.

• iPhone and Secure Wireless - PEAP

  We recently deployed a new wireless infrastructure using 4404 WLC and 1131 Access Points.  We have 2 WLAN, a secure using RADIUS (Microsoft IAS on Win2K3) and PEAP.  The other access to public comments using the authorization of web WLC.

  We discovered that iPhones and iPod touches are able to connect to the WLAN secure with only their powers of AD.  They are then invited to accept the certificate and granted access to the WIFI secure.

  Our field machines require the certificate be installed via Group Policy, so I'm not sure how Apple devices are pulling down from the cert.

  Does anyone have any suggestions on how to do to block this behavior?  We would like that these devices use only access visitor web-auth.

• JUMP requirements?

  XP natively supports it LEAP without Cisco aironet cards, or cards required Cisco?

  -John

  Well, you will indeed need a certificate on your AAA servers. I know that Cisco ACS servers can generate a self-signed certificate if you don't want to buy one from Verisign, or implement your own certification authority; I presume that MS IAS can do the same thing but have not tried.

  Other certificates, it's not that complicated: make sure that your AAA server will manage PEAP; Make sure that your APs or WLCs are set up to 802. 1 X; Make sure that your clients are configured correctly for enterprise WPA(/2) and PEAP. Disable the automatic use of the Windows login if necessary.

• Using PEAP get "authentication failed" in the event log

  I was able to get the Flint to work using JUMP, but no luck at all either with the PEAP Protocol.

  Can someone help me?

  Thank you!

  PEAP allows to authenticate wireless users without requiring that they have USER certificates, but we still need a ROOT certificate.

  Here are some more specific details on PEAP:

  ... 'the protected '.

  Extensible Authentication Protocol (PEAP) Version 2, which provides

  a tunnel encrypted and authenticated, based on the transport layer

  Security (TLS) that encapsulates the EAP authentication mechanisms.

  PEAPv2 uses TLS security to protect against rogue authenticators, to protect

  against various attacks on confidentiality and the integrity of the method internal EAP Exchange and provide the EAP peer for the protection of privacy. »

  "In negotiating TLS, the server presents a certificate of.

  the peer. The peer MUST verify the validity of the EAP server

  certificate and SHOULD also consider the name of the EAP server presented in

  the certificate to determine if the EAP server can be

  of trust. »

• ACS 4.1 forces Clients to use certificates for PEAP-MSv2

  I have a test WLAN I want to log on a user/pass field domain users, but also force them to use the public key of a self-signed cert from the AAA server.  Right now, I can get this working, if for example a windows client will connect to the WLAN if you set it to authenticate the server cert in the PEAP protocol options.  Unfortunately I can't prevent connection customers who have a valid user/pass but do not set or cannot set the cert to authenticate.  This would allow employees who have to say, an android or iPhone just to enter his user/pass combo and get an IP on the WIFI network.

  Can ACS be denied to all customers who themselves are not connected with the certificate of service installation?

  Authentication side certificate made by the PEAP Protocol Server is completely client-side.  It is a sad reality and a good reason to put in place things like on the desktop group policy to prevent users to bypass this security check.  The problem is in fact common to all technologies that rely on the trust of the certificate system. Who do you trust? What is the basis of your confidence? It is based on your list of root certification authorities trust that in an Active Directory environment can be controlled by policy.

  The main objective of the authentication server with the PEAP Protocol is to validate the client sends identifying information to someone he trusts. If the customer decides blindly trust everybody, there's not much you can do.  I don't know policies similar to those enforcement mechanisms available with active directory on iphone or other mobile devices.

  Because PEAP protects mainly the users to communicate their passwords to a man in the Middle, you could implement a security mechanism, incorporating the RSA tokens or another technology that ensures the password will be useless if intercepted.  Another option would be to provide a wireless connection more open then requiring these devices to establish a VPN connection.

• EAP chaining with the PEAP Protocol

  I was wondering if we manage EAP chaining with PEAP (not EAP-FAST). For some reason, it does not work for me.

  DS

  I think the answer is 'No', but it is a little more complex than that, because you will use EAP-FAST, EAP-MS-CHAPv2 n EAP - TLS. I have not myself deployed, but here is a link to a good document that describes the process of chaining EAP and requirements:

You must move the entire folder, not just the content.

  Reboot, re-launch Mail and test. If the problem is resolved, recreate the required e-mail settings and import emails you want to save to the folder on the desktop.

• Assistance required after you download Sierra - locked in a spiral of failure of the Installation

  Hello - I am a student of the University who made the mistake of thinking I had to upgrade my OS system after seeing some updates new flashy in the Sierra. Long story short, that my computer is locked into a cycle where I restarts and the installation process will begin installation but end abruptly and ask me to reboot again.

  I have exams and papers due and seriously want access to my data again. I don't have a back up of my files. As such, I am looking for a method that will allow me access to my files that I need to be able to read notes, print etc.

  Details: I have an old MBPro by the end of 2011. He was on as the primary OS x Lion. I had updated some time later. More recently, I got El Capitan and it worked very well. I downloaded Sierra in the background as I did work at home and after installing it, it asked me to reboot. This was the point that I was able to come back from. Reboot after installation scenario is as follows:

  -A progress bar comes up saying 34 minutes until completion

  -The progress bar goes to 33 minutes until completion

  -Beginning of fans of my computer acting upward and the bar stops and crashes of progression

  -The installation process says he doesn't have and asks me to restart my computer

  Specifically, I get the message 'Mac OS could not be installed on your computer. File system check or repair a failure. Quit the installer to restart your computer and try again. »

  When I quit the installer of the OS, I am taken to the startup disk option and asked to choose a system to reboot my computer with. I see 'Macintosh HD macOS 10.11.4' but when I click on it and try to restart I get the following error message, "you cannot change the disk on the disk selected. Startup disk could not gather enough information on the selected disk. »

  Things I've tried:

  Internet recovery mode: I went here to do a restore of the Mac OS x comes with my computer (Lion). This attempt fails and the computer tells me I can't downgrade because a more recent OSX is already on my computer...

  Recovery mode: I tried to come back just El Capitan from here. When I try to do the process will take literally one second before I get a notification saying: "an error occurred during the preparation of the installation. Try to rerun this application".

  Disk utility: I tried to do first aid and repair on this menu on the big disk image (since some of them pop up... I'm sure that the big one is my computer and the small setup of Sierra is?). I see that I 115Gigs franco 319Gigs departure. When I click on check and repair, the process takes some time and seems as he goes to halfway through before I get errors in the two. Repair error wonder backup my data.

  -some specific stuff; the journal for the repair of first aid says something like: the Macintosh HD volume could not be completely checked. File system check exit code is 8. Update support partition for the volume as required. File system check or repair a failure. Operation failed... »

  Safe mode: I can't start in safe mode. My computer will load the apple logo, progress on 3/4ths of the way start-up and then crash on its own and not restart.

  Things I have tried:

  Constituting a new boot USB of OS Sierra - I read that in so doing I can substitute the installation process that is going on right now on my computer and start a new... I hope one that works. I was not able to do this again, because I need someone to another macbook to make it and none of my friends won't let me touch their computers after the fiasco that happened on mine... Can I get some feedback on this?

  Backup: I don't have an external hard drive... I'm willing to buy one if necessary, but I don't know how to make a backup in a world where I don't have access to the major functional sections of my computer. Also, if my computer is * session here now, I'm worried that a backup will be essentially a * a backup... is this the work of the computer?

  Other thoughts:

  -my computer was working fine before I tried the upgrade... no complaints on my end, it was a real trooper

  -Maybe the download was corrupted?

  -I learned today that the operating system installation process requires internet connection - maybe that my internet connection is bad?

  -on that note, I want to say I tried a lot of different things. Been in different parts of the campus (different parts of my dorm building, IT support across campus, etc.). My University has also 3 options of WIFI, but each requires a separate verification process. Throughout this process, I have been connected to one of these methods. Switching may help? But, if I can't do the verification step (i.e. open a browser and type in the details of my student specific to actually use the web), I do not think that this will help you a lot. In addition, I am sure that I am already using one of the less frequently used options.

  I want to avoid a permanent possible deletion because there are important things on my computer.

  Any advice? Enjoy it!

  Same problem here on my Mac Mini end of 2012. I couldn't find any fix so far. The machine worked perfectly fine before with El Capitan and had about 50 GB of available disk space. I have use any version beta of Sierra, but officially released one that came yesterday. Really disappointing to see the new system operating software with fundamental questions and no good way to solve it.

  Any help really appreciated.
