Re: ACS authentication issue

Hi,

I went through your post. I'm only unsure about one thing that would you like to make the same servers certificate authorities where we have acs installed you want to install certificate on ACS for wireless authentication.

Anyways, I'm giving you info about both the options:

==## Configuring your Win 2003 server for an Enterprise Root Certification Authority ##==

http://technet.microsoft.com/en-us/library/cc700804.aspx#XSLTsection123121120120

==## In order to get certificate from CA and get it installed in ACS version 4.2##==

You may go through the attached PDF CONSITS ACS CERTIFICATE SCREEN SHOTS)

Re: ACS authentication issue

Hi,

Follow this doc to install self-signed cert. Once you install the cert than go to system configuration > global authentication setup > check peap mschapv2

You don't need IIS for this but if you still want here is the link:

Re: ACS authentication issue

Thanks for your help now tell me one thing in which case we use self-sign certificate in ACS and in which scenario we use server to make a certificate and then import in acs....i am very confuse regarding this concept......the wirless doesnt use any certificate all ACS is doing in our scenario that it is doing authentoicated the credintials of wirless (username and password) from a windows AD 2003 server......here i have to mention again that windows 2003 is a domain contoller.......so in this scenario which option shd we go for.....there is already a server primary one installed.....is there any way to check that what kind of certificate it is using....i tried my best but couldnt find it.........thanks again
