Wireless clients do not well known default trust certification authorities?

I use for wireless PEAP-MSCHAPv2 authentication.  The radius server is a Windows 2008 network POLICY server.  The customers consist of a bunch of laptops (especially on Windows).  Not all of these laptops are members of Active Directory.  Then, pushing any kind of policy to all customers is not feasible (ie.) using a public key private and AD infrastructure to push the server cert and Setup wireless for all members of the domain.  So we decided to use a public key public infrastructure and got a certificate for our radius by a known CA server.  So far so good.

When customers go to connect, they still get a nasty WARNING saying:

-STARTUP-

The credentials provided by the server could not be validated. We recommend that you break the connection and contact your administrator with the information provided in the details. You still can not connect, but doing so exposes you to risks of a possible unauthorized server security.
Details
RADIUS server: $radius
Root CA: $ca
The '$radius' server provided a valid certificate issued by "$ca", but "$ca" is not configured as an anchor of confidence valid for this profile. In addition, the '$radius' server is not configured as valid a NPS server to connect to this profile.
-STOP-
(I replaced the name of the actual radius with $radius server and the CA with $ca).
Do a little digging, it seems that it is just the expected behavior of the Windows wireless client?  What is the point to get a cert signed by a well-known certification authority, if the customer is still going to get a warning nasty like that?
Web browsers certainly do not behave like that.  The only difference between a web browser and the wireless client is a browser, you're still going after a URL (IE, you can match what the browser wants to connect to compared to what CN on the server cert is back with) while on the wireless client, you usually won't know the radius server you want to authenticate.  But, in both cases, the server cert is signed by a CA that is known.
I found a good post that talks about, but no solution:
Well, I guess that one solution is to manually configure the client for the certificates issued by the CA of confidence and/or configure my radius server in the connection profile.  But that requires the configuration of each client.  And there is no way that we can use AD to push a policy/cert to all customers.
So my questions are:
-is that really the expected behavior?
-so trust generally the default case browsers whose certificates are stored on the operating system by default, but not wireless adapters?

Hello

I'm not an answer full but just putting my 2 cents.

This problem is related with the begging of Windows wireless. Absolutely not your wireless adapter.

CSSC or Intel ProSet behave differently. (So if you have cards intel, you can check this option).

But I confess that I've never tried the authentication of the well-known certificate with a public cert of a certification authority

  • Server 2008 rdp client does not keep by default local printer

    Question: Windows XP workstation connects to the client terminal server 2008 for an application. The local workstation XP has a based LPT printer. The local printer is selected to be used through the RDP client and can be seen on the Terminal Server session. The central issue is that the RDP session will not keep the local printer the default XP workstation. It can be chosen and works, but never stays after the end of the session and reconnect or even log out of the session and you reconnect. It never remains the default printer, instead, it takes the default value of the server administrator. 1 of 7 other network printers.

    Points: The XP workstation has a printer LPT laserjet 4000 series as is the local default LPT. I followed a Tech Note "http://support.microsoft.com/default.aspx?scid=kb;en-us;302361" which seems to have nothing to do with this topic.

    Note: The server is standard with clients more Terminal server 2008. All the network printers according to works, and other customers to keep printers default network without problem.

    Annex Note: http://social.technet.microsoft.com/Forums/en/winserverTS/thread/2a6944a1-d1cb-492c-b413-75dcbe7dad9b is linked. I have this strategy enabled for all other customers. I guess what would be necessary, would be a work around.

  • Cannot perform this operation because the default mail client is not properly installed... help

    I can't send an e-mail from a link on a page without getting this error... "could not perform this operation because the default mail client is not properly installed"...    My windows mail is set as default and I can receive and send him good, please help.

    Thank you

    A program is defined as default does not mean that it has considered all of the default roles available.  In the case of Outlook 2007, there are 13 total default values that can be assigned, and it should have each of them.  It is possible to default Outlook for e-mail, but not the default value for write links in web pages.

  • "Could not perform this operation because the default mail client is not properly installed" when you use Windows Mail

    Original title: loss of entrance of Protocol in the list of saved files

    I use an old Toshiba laptop of two year with Vista as an operating system. It came with a trial version of Microsoft Office already installed. I had no use for it then after the trial expires I uninstalled. This seems to have created a minor problem with the e-mail program. When I visit a Web site and click on 'Contact us' I get an error message as follows "cannot perform this operation because the default mail client is not properly installed." I suspect strongly as during the uninstallation of office he removed a protocol in the list entry, similarly, the bottom of the list of the saved files. A check with other similar computers with Vista installed seems to confirm this. If someone at - it a quick fix to this problem? I don't want to resort to installing a whole new email software to fix this minor problem if I can avoid it.

    Hello Karena R, yesterday, I downloaded and installed Windows Live Mail, and I must say that I prefer Windows Mail Live Mail program. After making sure that Live Mail is the deafult for all messaging functions and that the entry "Mail Protocol" was now back to the list of saved files, I checked the problem mentioned in my original post. He is not fixed! Another small problem is fixed now if. In my "drafts" mailbox I have some e-mails stored there and when I click on one of them upwards now comes an email with the appropriate address inserted in the address line. Who could not before. I used to get this error message, which is now the new title of my post. So why the difference when I click on email address that I find on Web sites? Now, I also find that by Michael following the instructions (below), I do not see an entry "mailto" but his suggestion to step d. type in "URL Protocol" is not appropriate because it is already there. The installation of an entirely new email software should have my computer all the necessary entries for the new program to function properly in all respects. So what's happening? It begins to look as if uninstalling the program Office has pulled something real Vista operating system.

    It's a good thing, I thought of the research on other boards for my missing post.

  • Web interface works is not the well-known address of management

    TLDR:

    • opening webinterface on ip management group-> does not work / ping
    • opening webinterface on eql management ip-> works
    • opening webinterface on ip management group-> suddenly done work
    • Why?

    Yesterday I've updated SanHQ of 2.2 to 3.0.1 to prepare to run the path to upgrade to FW 7.x. Since yesterday, I get the following warning:

    [ID: 1.6] The eql-grp01 group has been added using non well known address (MWKA). Delete and add the group using the well-known address of management of group 172.16.0.9.

    The eql-grp01 group contains a single EQL (eql01 / 172.16.3.15) and has a dedicated management port. The beach is a 16, as such, both the IP and IP management EQL management group are in the same network (again).

    I'm able to reach the Web interface of eql01 on 172.16.3.15 without problems for years. Try to reach the Web interface on 172.16.0.9 has always given problems (timeout, ping works however) until I asked the Web interface on 172.16.3.15, after that, I can reach the Web interface without problems on 172.16.0.9.

    Up until now I did not worth to look into it, but as I'll be add another Member to the group within a few weeks and SanHQ's "tenacious" on do not use well-known management IP address I have tought I might give it a try here, maybe it's the behavior?

    Edit: Adjusted the subject as non-MWKA does not work but the MWKA (submits sugested otherwise)

    OK, you need remove the SANHQ and add in it through the Well Known management address.

    I don't know why he first had to go to the Member port Mgmt vs being able to use the IP alias for group management.

    That's all the management IP address is, like the IP address of the ISCSI discovery.  It is a superior a physical port IP alias.   So if you can reach the Member IP address, you will have no problem reaching the alias.

    Maybe something on your network, or the ARP table has not been updated.

  • Default mail client is not properly installed

    I get this message when I click on an e-mail link. Default mail client is not properly installed. How can I fix it

    Happends error because you have installed/used a different browser, then Internet Explorer, then during the uninstallation of the browser, you have broken the link between your default browser.

    The e-mail client has no path. To fix it, try to open your current browser, go to tools > Options, and then set the default browser. Close and your e-mail program. Re-open your email and try to open a hyperlink again, see if that fixes.  If not, go into Internet Explorer (if you are not already) and go to tools > options > advanced down, press reset, do not forget to reset personal settings, and then make sure the "default" browser is selected, and close.  This fixed my problem and is recommended for a few other places, give it a try.

    Edit: If it does not, what email program are you using?  Set it as default value (via the options of the program) also do so via the browser, Internet Explorer you go tools > Options > and set your e-mail by default also program...
