802.1x - fallback to unauthorized network access

Hello
Is there possible to uncheck box "fallback to unauthorized network access" for 802.1x via GPO?
Cheers,
Kriss

Hi,
There is any other way to uncheck this option on client machine? e.g. regedit
Hi,
I'm not sure, but you can try to use RegShot to capture the Registry changes after deselect the option. After that, using
Regshot make a compare should be able to find the key registry key.

Disabling Fallback to unauthorized network access in GPO

Hi,
I am trying to control (disable) the "Fallback to unauthorized network access" settings via GPO from DC. How can I do it?
Thanks.

I found this thread while looking for the same GPO setting.
There is an excellent resource created by David Marin Hebra on how to setup 802.1x for SCCM and MDT.
In that document, it details how to export the wired policy to an XML file.
netsh lan export profile folder=C:\Test\8021x interface="Local Area Connection"
This XML file shows all the config that is applied via Group Policy, and can be added to a non GPO machine to see what all the settings do via the command:
netsh lan add profile filename=C:\Test\8021x\"Local Area Connection.xml" interface="Local Area Connection"
As stated by Greg, the setting corresponds to the OneXEnforced setting in the XML file.
This is by default set to "False" - and this corresponds to the checkbox
checked for "Fallback to unauthorized network access". If you set the XML entry to "True" and apply the profile, you will find that the checkbox is
unchecked.
This setting can be found in the GPO as "Enforce advanced 802.1X settings", if you set this policy setting and apply the GPO, you will find that the checkbox for "Fallback to unauthorized network access" is
unchecked.
Looks like you cant have one without the other.

IMac/Mavericks won't Wake for Network Access

I just migrated to a 3TB Fusion drive iMac and it will not awaken when the network Apple TV tries to load the iTunes library... on WLAN
Energy Saver/Wake For Network Access is checked
I even UNchecked Put Had Disks To Sleep
Computer Sleep 1 hour /Display Sleep about 5 minutes
This worked before on my previous iMac/1TB/Lion on LAN
Any ideas? (Other than setting Computer Sleep to NEVER)
Is it because I'm on wireless now? :-/ Does "Wake" require a LAN connection?

Hi,
I have the same problem. I have also checked the settings as described.
It is really annoying that if I want to use my new Apple TV to stream from the iMac, I have to go upstairs and wake it up first.
My wireless network is via a Sagem router using Channel 2 and 802.11g.
Generally wireless network access is just fine.
Problem is just that the iMac won't wake from sleeping.
Could any installed software be interfering?

Airport Extreme 802.11AC + 5th Gen and guest network access

I have the current gen Airport Extreme 802.11AC with a 5th Gen extending the network. With this setup, I am unable to login using our guest network setup. I have tried using guest network with a password and one without but its the same results. When a guest logins, it stuck attempting to login with no error messages.
So is it possible to have this configuration and still have guest network access?

Please review what I said originally.......that the guest network function on the AirPort Extreme is designed to work with a simple modem......so the AirPort acts as the main router for the network..
Another way of saying the same thing is that the AirPort needs to be "in charge" of your network for the guest feature to work correctly. The AirPort cannot be in charge if it is connected to another device that is already configured to be the main router on your network.....your Actiontec modem/router.
The Actiontec device combines the functions of a separate modem and a separate router in one package. This type of device is known as a modem/router, or also known as a gateway.
Some folks call a modem/router or a gateway......a modem. So, things can get confusing.
I do not know if it is possible for the Actiontec device that you have to be configured to act as a simple modem.....so the routing functions of the device are completely turned off. (Turning off the wireless on the Actiotec does not turn off the routing function).
If you turn off the wireless on the Actionec, it becomes a modem and a wired router. And that wired router is still in charge of your network.
The guest network feature will not work correctly unless the AirPort is in charge of your network.
My suggestion was for you to ask your Internet Service Provider (ISP), if they could supply you with a simple modem. That is all that you need. You don't need two routers....and the Actiontec that you have now is not allowing the guest feature to work correctly.

Acs 5.3 and wlc 2504 config with restricted network access

Hello,
i submit you the following issue that i'm actually facing:
i must configure a secured wireless network with access restriction based on SSID. the equipements are : cisco wlc 2504 (soft 7.3) cisco secure acs aplliance 1121 (soft 5.4) .
the users that will connect to the network are regrouped by identity groups, each identity group having it's own SSID. Clearly each group of users must access only one SSID.
i followed the procedure below to configure it:
-- creating user identity groups;
-- creating users and assigning them to the groups;
--- creating authorization profiles for each SSID under policy element/ authorization and permission/network access/authorization profiles and putting the Airespace-Wlan-Id(the SSID number) in the radius tab.
--- assigning the authorization profiles to the identity groups under access policies.
after all these config the users can access the network using there userid/password configured. But the problem is Every user can access every SSID, seems like the restriction is so not very well configured.
i found some documentation on this kind of config but the version of ACS used seems older than the one that i use, so menu are very different.
Please can someone provide with the right steps to follow to achieve this kind of config.
tkx in advance

Yes.. you only have to add the end filter like what I posted... as far as the calling station id in the WLC security tab, it doesn't matter because that is not used when using 802.1x. I would also try to not enable everything that you have just to start from the basic and make sure it works first. The WAP Authentication Method might or might not work for you. Uncheck that for now and when you have a successful authentication, look at the monitor log and see what radius attributes are being sent, because those attributes is what you can use to build your policies.

Is it possible that network access permission control in acs 5.1

Hello
We have ACS5.1, WLC 7.0 and using 802.1x to authentication users.
Anybody know how I can configure network access restriction with using internal user group information.
For example, under the same SSID(like that "test") , same VLAN ID.
But two different user group has a different network access permission.
One group has full permission and the other has a limit network access permission.
Is it possible?

The equivalent of a NAR would be ACS 5.1 returning an authorization profile after authentication. Just configure your authorization policy to return one profile for one group of user and the other profile for the others.
Now to restrict access to the network, I think you're best with an ACL ? So link ACLs to your profiles.

How to do .1x port based network access authentication through ACS

How to do .1x port based network access authentication through ACS.

Hi,
802.1x can authenticate hosts either through the username/password or either via the MAC address of the clients (PC's, Printers etc.). This process is called Agentless Network Access which can be done through Mac Auth Bypass.
In this process the 802.1x switchport would send the MAC address of the connected PC to the radius server for authentication. If the radius server has the MAC address in it's database, the authentication would be successful and the PC would be granted network access.
To check the configuration on the ACS 4.x, you can go to http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.1/configuration/guide/noagent.html
To check the configuration on an ACS 5.x, you can go to http://www.cisco.com/c/en/us/td/docs/net_mgmt/cisco_secure_access_control_system/5-2/user/guide/acsuserguide/common_scenarios.html#wp1053005

Unauthorized Keychain Access - System

When I opened up the keychain access from Utilities I found something very strange. Under "System" I found an access titled " F* Bush", kind="airport network access", keychain="system". It took place on the same day I switched and installed a new wireless modem router (model DLINK DSL-G624T). On that day I also synchronized with my MacbookPro, which had unauthorized access over 1 year ago from this same "user" due to no encryption on the wireless network (didn't work with MacbookPro and former Netopia router which is why I changed).
When I try to "show password" and enter the admin ID and password I get a message "kcproxy wants to use your confidential information stored in "f* bush" in your keychain. Do you want to allow access to this item?"
Should I be concerned about this? I currently have WAP security in place to block unauthorized access. Not sure if it is too late.

Thanks for the link -- the thread was most helpful. Since this all came about as a result of changing my Active Directory password on the corporate network, the info in that thread tends to confirm my suspicion that the system entry is overriding the entry that I changed.
I'm not sure that I agree with Jim R.'s commentary, though:
Nobody owns the system keychain really, not even root. The System keychain is a shared keychain the system uses the store items available for all user accounts on the computer. If it were owned by root and had the root password, then other accounts would need the root password in order to use it. The fact that it doesn't allow you to view stored passwords is a security measure. This way, users can use system-wide resources that have been set up without actually knowing the passwords, not even other admins.
The reason for having root is to be able to alter system resources that others can access. There are many other resources in the system that can be accessed by everyone but altered only by root. Now we can argue about whether others in the System Admin group can modify a resource, but root should definitely be able to access and alter every resource on the system; every other O/S I've used has at least one such account. Without it, you give up the ability to control your own system.
Thanks,

My laptop is showing no network access whenever i try to connect

Hello,
Am a new comer here, and am from Nigeria. I have an issue with my laptop since two to three weeks ago. I can't connect to internet since two to three weeks ago, whenever i try to connect either through wifi or modems, it always give me no network access at the base of network icon.
Can anyone help me out as i have tired everything i can. There is 802.11n Wireless LAN Card, Bluetooth Device(Personal Area Network), Bluetooth Device(RFCOMM Proyocol TDI), Microsoft Visual WiFi Miniport Adapter and Realtek RTL8102E/RTL8103E Family PCI-E Fast Ethernet NIC (NDIS 6.20) installed on my laptop.
Thanks

Try Settings>WiFi>Your network Name>Forget this network. Then go back to Settings>WiFi>Your Network Name. You should get the option to enter the password again.

Wake for network access what has happened?

Hi everyone...
When snow leopard came out I tried the wake for access feature and used it quite often... Because the computer screen used to come on at night (no clue why) I reluctantly turned the feature off. Now I would like to reuse it and it doesn't want to work.. Why not? Is there a system preferences file that is corrupted?
First my setup:
iMac running 10.6.3 under energy preferences I've rechecked wake for network access. This is connected by ethernet to
My airport base station running firmware 7.4.2 and it is a 802.11n model and as such "wake from sleep over network" compatible
trying to access the imac is a macbook (early 2009) also running 10.6.3
Now when the computers are running, they show up under "shared" and I can connect/share screens without a problem.
Sadly when the iMac is asleep it doesn't show up under shared (it used to when I tried the feature last Winter.
The only difference that I am aware of is that my imac was repaired a couple of weeks ago and the whole motherboard and network components were exchanged. Could that have anything to do with it?
Also I do change preferences fairly often. Is there anything that I'm missing? On a related note, I do now hear my computer sometimes cycle up (screen now off), which makes me think the system is waking up to report to the base station. But why is it not showing up?
Thanks for any and all help. Hope everyone has a good start to the week.

Network Access Module and Switching Users

We are working on implementing 802.1x and plan to use AnyConnect NAM on the PCs. However, I’ve run into a problem where we have a few multi-user machines for employees who work in multiple locations throughout the day. It’s not uncommon for someone to lock the PC they are working on and walk away. Prior to NAM, a second user could come along and log in as themselves, leaving the initial user logged in. However, I’ve found that once NAM has been installed this user switching feature is disabled. This is understandable, as the initial user technically hasn’t logged out, so the port is still authenticated with their credentials, and we wouldn’t want to accidently break a connection stream just to reauthenticate the second user.
I have spent quite a bit of time going through these forums and white papers trying to find an alternative solution for this situation, but haven’t had much luck. Does anyone have any suggestions on how I could proceed on this?

What changes does Network Access Manager have to do into Windows to work fine?

We are deploying the Network Access Manager in Windows machines to work in 802.1x cenario with CISCO ISE. In some machines NAM doesn't work well. What Windows 7 features does NAM module have to interact with Operational System?

We solved the issues with a custom package made with WISE and we deployed it with Microsoft SCCM.
SCCM works with a System Account to install applications and we deduced that issues happened because the account privileges to install AnyConnect in some machines was not enough.
Thanks for all.

ACS 5.3 - 11033 Selected Service type is not Network Access

I have some older devices on the network that only support RADIUS (not TACACS) for authentication and would like to have them use SecureACS 5.3
I understand that by default, ACS only supports TACACS for device administration. So I'll get this error when trying RADIUS:
11033 Selected Service type is not Network Access
Description:
RADIUS requests can only be processed by Access Services that are of type Network Access
Resolution Text:
Verify that the Service Selection Policy rules are correct
However, even after adjusting the Service Selection rules and seeing hits, I still see the same message in the logs, as if it has no affect. Any Ideas?

If you use the protocol as radius you can not use a device admin service. You can only use network access. That will allow you for authentication to the devices.

ACS 5.3 cannot create default network access authorization rule

Hi, when I click 'Create...' under Access Policies > Default Network Access > Authorization, and then press the 'OK' button, it says 'Please configure at least 1 condition.' However I have no way to configure conditions as the 'Conditions' text is just bold text and not a link or any sort of configurable area. If I go to 'Customize' on the bottom right and add conditions to the right list box, I still have no options when I press Create. Also, the 'green light' next to Default Network Access is grey with a line through it. This is the most cryptic system I have ever used.. anyone have an idea? Thank you!

Looks like you are using chrome amd it's not a supported browser.
