Auth-fail vlan won't support re-authentication

We're using ACS 1113 Appliance with ACS version 4.1.4.13. via the RADIUS attributes, clients are re-authenticated every 16 hours. The machine cache is set to 12 hours. This means that, if the user doesn't log off within 16 hours, he will be denied network access because of Machine Access Restriction (which is normal).
The problem is, at this point, the SSC client keeps trying and trying to authenticate. It never stops trying until the user logs off or reboots (sometimes this can takes days to weeks (f.e. on vacation). This results in a log entry, every 4 seconds (because of timeout tx-period settings), for every user that is in the MAR. Now you can imagine that, in an environment with 4000 users that the loggings become unusable because of the enormous amount of (unnecessary) failed attempts logs.
I've tried the following dot1x attributes on the switchport but they don't seem to work:
dot1x max-req 3
dot1x max-reauth-req 3
I was hoping they would stop the authentication attempts after 3 unsuccesfull tries, but it doesn't help.
Then I thought I found a solution: the auth-fail vlan. Then we have only 3 logs before the port falls into auth-fail, which is much better.
But, once he is into the auth-fail vlan, he never gets out! I tought that, if the user logs off, the network connection is closed, so at that point the machine authentication would be triggered. But he just stays in the auth-fail vlan until rebooted or the cable is removed. Isn't there any way to trigger the authentication when the user is logged off?

Check if the "Default connection timeout" and "Default Association Timeout" values are configured properly in the client policy. Also check for the "max start" value in the connection settings for 802.1x. http://www.cisco.com/en/US/docs/wireless/wlan_adapter/secure_client/5.1/administration/guide/C2_SetupSSC.html#wp1056892

802.1x Auth-Fail VLAN --- XP does not recognize

With Auth-Fail VLAN configured on Cisco 3550 the Switch successfully configures the port to the configured auth-fail vlan upon unsuccessful authentication. The PC even gets the IP address from DHCP.
However, the Windows XP network icon on the task bar continues to display as if it is trying to configure the network. The popup text displays "Attempting to authenticate" whereas the PC is fully connected and able to communicate on the network.
Any idea...????

I am performing machine authentication against MS AD. It does get an ip address from the authentication VLAN but not before minor delay...(have seen up to a minutes delay in some cases).
The following is working fine in my case:
Machine Authenticaiton (S) ---> User Auth (S) then all is good.
Machine Auth (S) ---> User Auth (F) transition to Auth Fail VLAN
Machine Auth (F) ---> Machine is in AuthFail VLAN then User Auth (S) Machines transitions to correct access VLAN (or RADIUS assigned VLAN).
There are times when the behaviour is a bit variable in terms of VLAN assignment. Reading the IOS guide it makes sense if you are not assigning VLAN through RADIUS then switch sometimes tends to leave the port in the currently assigned VLAN, which depending on the port state (success/fail) could be the access VLAN or the AuthFail VLAN.

802.1x Auth-Fail VLAN and Guest-VLan not available

Hi Pros,
Having an issue with an 881 I have recently acquired. I'm wanting to setup a Virtual Office scenario. Everything is working fine except for 802.1x...
I can get the 881 to authenticate things connected to it, but I don't have the options of guest-vlan or auth-fail vlan.
Idea is if the users takes the router home and someone, either accidentally or on pupose, connects an unauthorized Laptop, they stay off the Corp network but can get to the internet still.
I found this link on Cisco's site:
http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6660/ps6808/deployment_guide_c07_458259_ns855_Networking_Solutions_White_Paper.html
That link shows them configuring a guest vlan right on the fa0-3 ports of an 881W. I dont have that option on mine. I can only configure 802.1x on the vlan interface. I have 802.1x working, for things that connect to vlan1, but I would like to have a "fallback" setup.
EZVPN_Remote(config-if)#int fa1
EZVPN_Remote(config-if)#dot
EZVPN_Remote(config-if)#dot1?
dot1q
EZVPN_Remote(config-if)#dot1
EZVPN_Remote(config-if)#int vlan1
EZVPN_Remote(config-if)#dot1x ?
default           Configure Dot1x with default values for this port
host-mode         Set the Host mode for 802.1x on this interface
max-reauth-req    Max No.of Reauthentication Attempts
max-req           Max No.of Retries
pae               Set 802.1x interface pae type
port-control      set the port-control value
reauthentication Enable or Disable Reauthentication for this port
timeout           Various Timeouts
Any thoughts why I'm seeing this behavior? Feature-set? IOS Version?

Auth-fail VLAN vs Guest VLAN

Hi All,
What criteria is used to determine whether to use the auth-fail VLAN or the guest VLAN?
What if a non-802.1x client connects to the port, say a Vendor.... 802.1x doesn't occur, so does it then transition to guest vlan?
What if a vendor brings in an 802.1x capable PC and connects it... the auth fails, but I'd want the vendor to go into the guest VLAN anyway, Could I give them a temporary username / PW maybe to authenticate with? hmmm...
Thanks in advance.

Hello,
     The Auth-Fail VLAN is invoked if an Access-Reject is received from the Radius server for the
     user or machine authentication. The Auth-Fail VLAN will be invoked after a number of failures
     not after the first authentication failure. This is a configurable value.
     The Guest VLAN is invoked if not EAPoL traffic is received from the connecting client.
     You can set the Auth-Fail VLAN and the Guest VLAN to the same VLAN ID if you want
     users who come in with the supplicant disabled or someone with invalid credentials (or no credentials).

Authentication failed Entourage doesn't support available authentication...

I tried to set up and exchange account through Entourage. It works fine for receiving, but I cannot send through the account, I assume because I do not have a Certificated Authorization. So I tried to create a Certificate, since the help and instructions suggested such. This meant I had to create on in my Keychain.
Well nothing worked, so I decided I would cheat and just create an account to send from Entourage using my exchange email account as an alias. The down side being exchange would not capture the "Sent" messages. Oh Well, I could live with that.
This is when I started getting this error and Entourage would not send the message:
"Authentication failed because Entourage doesn't support any of the available authentication methods."
I eventually learned to go to the Keychain and try to verify the error and repair it. The error that appears on verification is:
"Item “mail.bellsouth.net” has unspecified value for port attribute"
Once the repair is executed, it shows it is repaired, but Entourage will still not send mail. So,...yes there is more...I decided to create an identical account to my working bellsouth account, that still works perfectly by the way, and the new account demonstrates the same problem and will not send, but all settlings are identical to my original POP3/SMTP account.
Help! I do not have time machine running, but that is another issues, so lets see if I can fix this first.
Thanks for whoever can come to the rescue!
BarryCuda

I believe this is a KeyChain issue, not an Entourage issue, but it is hard to tell. Can you tell? The reason I believe this is because I now cannot create an duplicate Account and have the KeyChain work properly with Entourage.
I will post there as well, but please provide some guidance if you can. Where would I post KeyChain issue? I couldn't quite find a germane Forum.
Sorry if I posted in the wrong place, but I have to start somewhere since it is not clear where the problem lies.
Thanks,
BarryCuda

Auth-Fail Feature and Windows 802.1x Supplicant Compatibility

As per Cisco IOS design when authentication fails the switch sends a simulated EAP-Success message to the client so that DHCP can be implemented by the client. Taking into consideration the dot1x auth-fail command is configured.
However we have noticed that when using the built-in Windows XP SP2 802.1x supplicant and authentication fails, the Windows supplicant does not like this Cisco simulated EAP-Success message and drops the packet, therefore never re-initiating the DHCP process.
I have attached the Microsoft supplicant log indicating the dropped EAP-Success.
We are using catalyst 3750 with IOS 12.2(25)SEE. We have also tried release 12.2(35)xxx but issue persists.
Your suggestions would be appreciated.
Thank You,
ET

An EAP-Failure is by design. This occurs on all failures. The session fails rather normally. After the third (default but configurable) successive failure, the port is conditionally enabled (and placed in the auth-fail-vlan) even though 1X is configured and operating.
At this point, it's up to the supplicant to access the network if it wants to, since the port has been enabled. Without the notion of a controlled port on a supplicant, there's no reason it shouldn't try and access the network ;-).
Once a workstation is authorized on the network, and then subsequently fails for whatever reason, and put on the auth-fail vlan then it's also up to the machine to renew it's IP if it needs to. Optionally, you can configure the auth-fail-vlan to be the same as your default vlan. I guess it's worth pointing out, that you'd have this problem without 802.1X (changing VLANs on the fly for example). Some supplicants can deal with this though.
If an EAPOL-Logoff does not come from a supplicant (and it doesn't by default with Windows-XP) then there's nothing to get the port out of the Auth-Fail-VLAN either (short of link down). You can configure this through registry though. So the answer to your earlier question was no .. it shouldn't.
I'm not sure I understand the "IB" and "OOB" references here though.
Hope this helps,

Cisco ACS 5.1 802.1x auth fails on LAN when WLAN connected

I am running Cisco ACS 5.1 802.1x with certificate based authentication for Wired and Wireless connections. The issue that I am having is that when a user comes in from home with their laptop the wireless connection works, they pass the authentication and have network access fine. But when the plug the laptop into a docking station the LAN connection fails and gets put in the Auth Failure Vlan.
A reboot of the phone/ shut/no shut fixes this, but I really need to find a resolution
This is an intermittent fault and only effects users with both LAN and WLAN enabled.
Running ACS 5.1.0.44, all Cisco 3750s - c3750-ipservicesk9-mz.122-55.SE.
Certificates are issues by group policy and only using computer authentication.
any help would be greatly appreciated
Thanks

After a long TAC case with Cisco we discovered that the Mitel phone was not sending the EAPoL-Logoff packet so the switch still thought that the device off the back of the phone was connected.
There are no EAPoL-Logoff messages seen on switch when laptop is disconnected/port is shut down.
http://www.cisco.com/en/US/docs/solutions/Enterprise/Security/TrustSec_1.99/Dot1X_Deployment/Dot1x_Dep_Guide.html#wp386903
This feature is supported by most IP phones - I do not know if Mitel phones support that but we cannot see this message in the debugs you sent.
As a workaround we can configure inactivity timer (by default it is infinity):
http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_55_se/commmand/reference/cli1.html#wp11888691

Never mind, the correct command is:

wls:/nm/IDMDomain> nmStart('AdminServer',props=pr);
It would be interesting however to have a list of all names of environmental variables that we can possibly set.

Can't read or write some files, internet is failing, youtube won't load, software I tried to install was in Slovenian, not dutch or english like in my systempreferences settings, pictures and files won't preview with spacebar, etc. Malware?

Specs:
iMac 10.8.5
3,4 GHz Intel Core i7
32 GB 1600 MHz DDR3
Can't read or write some files, internet is failing, youtube won't load, security software I tried to install was in Slovenian, not dutch or english like in my systempreferences settings, pictures and files won't preview with spacebar and are randomly corrupted, when I entered something in the Youtube searchbar (when it was still working) it send me to a site with sexadds.
I tried restart my iMac and when I was logged back in, my dock preferences were reset.
Also tried to download some security software to check my Mac for malware, but when I did, I tried several, I got a notification that said something like 'dumpfiles (don't know if this is the right translation...) damaged'.
I'm taking screenshots from all the weird notifications I get and even three quarters off the screenshots I took in the last three hours are already unreadable.
It started this morning when I tried opening a Premiere Pro file on which I worked the night before.
When I tried opening it, it said the file was damaged and could not be openend.
I tried opening it with AE or importing the file in a new project but nothing helped.
When I tried looking for autosaves, this is the really weird part, there were none.
Even though there are autosaves from my other projects, this one was completely gone.
It looked like the day before never happened on my computer.
Also when I openend Premiere all the recent projects had been wiped.
So at first I thought it was a Premiere Pro failure.
But than, later on the day, I tried loading some RAW files from my compact flash card.
This is where I would get an error (error -36) which said some data cannot be read or written.
I tried importing the files with a view different technics, from dragging to importing via Lightroom and I succeeded with Image Browser.
But when I tried moving the files to an other folder the same error occurred.
While dealing with this issue I wanted to put on some soothing music on youtube.
This is when the next weird thing occurred: youtube wasn't completely loading in Chrome. I refreshed a view times, checked the internet connection and still no difference.
When I tried in Safari it did work but when I clicked enter on the searchbar in Youtube, a page with sexadds appeared (I didn't install AdBlock in Safari...).
I read about this 'phishing' where you are redirected to a site were a possible malware installment can take place...
I don't know if it's connected to any of the problems I've been having but I just never experienced this on a mac, I have been a Mac user for 10 years now.
On top of it all, internet started working worse and worse and now it's not even working at all. I had to fill in the password over and over, normally it remembers.
Just like my system preferences, all the preferences I had with Chrome where also reset.
Also somewhere in between I got this notification: Mac OS X must restore library to run programs. Type your password to allow.
To me this is all very weird and suspicious. I have clearly no idea what's going on. Could this be another sort of trojan horse or malware?
Some background info which could be helpful for solving this mystery:
two months ago the one year old Fusion Drive in my iMac just broke out of nowhere.
I got it replaced by a qualified apple repair store.
When I got my computer back, all the files where gone.
I got on the internet without AdBlock installed yet.
A game or whatever it was, can't clearly remember, got installed by accident.
I deleted it immediately.
Only two weeks later, I couldn't log in to my account. It didn't recognize my password and username.
So I brought my mac back to the store.
Here the repair guy said it was a minor thing and he just needed to reconnect my account. He also mentioned he found a downloaded game name Sparta and it probably had something to do with the error.
I asked him; could it be a virus? He replied no way.
I don't know why I couldn't be a virus, just because it's a mac doesn't mean it cannot be done.
So today I tried installing anti virus software (such as avast- was in a weird language looked like slovenian, clamxav - was in slovenian) but I couldn't install them.
PLEASE help me! I don't know what to do anymore, I work fulltime and I need my computer, I have no time to bring it in for repair, are there other perhaps easier ways?
Could this be the work of a virus or a malware? Or is it a disk permissions issue?

It sounds like you may have multiple problems, but none of them are likely to be caused by malware.
First, the internet-related issues may be related to adware or a network compromise. I tend to lean more towards the latter, based on your description of the problem. See:
http://www.adwaremedic.com/kb/baddns.php
http://www.adwaremedic.com/kb/hackedrouter.php
If investigation shows that this is not a network-specific issue, then it's probably adware. See my Adware Removal Guide for help finding and removing it. Note that you mention AdBlock as if it should have prevented this, but it's important to understand that ad blockers do not protect you against adware in any way. Neither would any kind of anti-virus software, which often doesn't detect adware.
As for the other issues, it sounds like you've got some serious corruption. I would be inclined to say it sounds like a failing drive, except it sounds like you just got it replaced. How did you get all your files back after the new drive was installed?

BT usb Dongle won't support headsets?

I just purchased a Motorola PC850 (usb BT adaptor). It's suppose to have A2DP so I thought it would work with my Plantronics 590A. If I check headset in the devices for the BT setup the next screen says "Bluetooth hardware won't support headsets".
But if I check other devices in the BT setup I get the Plantronics in my list of devices but I end up waiting fornever fort the pairing to complete. It just wont pair.

Upon further research I have learned that A2DP is not supported with any OSX 10.4.11. I think using Jack might be as close as I can get.

For 'Reason' if you get the message "Failed to Open MIDI Support Library"

I tried to open Reason 3.0.5 with an MBox 2 on my new MacBook Pro (Leopard) and I got this message: 'Failed to Open MIDI Support Library.' When I went to my 'Audio-MIDI' setup on my Mac, nothing loaded properly...
I found the solution to this problem after looking around online, and figured other people might be having the same problem, so here it is...
First, create a new folder on your computer desktop and call it "Old MIDI Drivers" (or something similar), then go to Macintosh HD>library>audio>midi drivers, and move all the drivers (that you don't plan on using) from that folder into your "Old MIDI Driver" folder on your desktop. For example, I moved all the drivers out except for my MBox 2 driver.
After you do this, you may have to restart your comp. (I didn't) and Reason should run.
Hope this helps...

(No biggie, but if you mark your own post as 'Answered' then people searching for answered posts will be able to find it more easily…)

"Failed to open midi support library". What is missing? And if so, how do I get it back? What to do?

I own a new Macbook pro 15" quadcore with OS X Mountain Lion 10.8.4
When trying to start software Reason 7 I only get the message "Failed to open midi support library".
What is missing? And if so, how do I get it back? Reinstalling Mountain Lion did not solve anything.
What may I do? Is there separate MIDI-drivers or else that Macbook needs to be running audio at all?
My audiocard Apogee Duet 2 is´nt working well either and I cannot even open the MIDI-window in Mac,
so that road is blocked. I´ve seen more ppl having problem but found no explaination.
Some say to remove midi-drivers but that folder is empty (or hidden?) when opening.
Also, Garage Band cannot open. It´s no problem with graphic apps, only with audio/midi.
My 2011 Macbook pro13" with OS X Lion runs like a charm. So how can this be? It really puzzles my mind.
Have thoughts on having OS X Lion on the new Mac as well but will not do it until I know where the real problem is.
Hope there is an easy fix to it. Thanks in advance.

When I use find file http://www.macupdate.com/app/mac/30073/find-file (which does tend to find files that "Finder" can't), it's not coming up with any other itunes library files that have been modified in the past week, which I know it would have been - unfortunately, I don't have a very recent backup of the hard drive. It would be a few months old so it wouldn't have the complete library on it....any ideas? I'm wondering if restarting the computer might help but have been afraid to do so in case it would make it harder to recover anything...I was looking at this thread https://discussions.apple.com/thread/4211589?start=0&tstart=0 in the hopes that it might have a helpful suggestion but it's definitely a different scenario.
