PEAP-GTC needs server-side certs only.

EAPFAST-GTC should work without certs at all.

Hi,

PEAP(EAP-GTC) works with LDAP, compatibility table,

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_soft/csacs4nt/acs41/user/overvw.htm#wp858207

Configure ACS for PEAP authentication.

http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_configuration_example09186a0080545a29.shtml

And when it comes to configure client, generally I have seen with Intel clients, you have an option to uncheck "Validate Server Certificate" under "PEAP Server" section if you do not want to install CA root certificate on every client, after you have selected Authentication type as PEAP and authentication protocol as GTC under "PEAP User" section.

As you explained eap-gtc is suitable for us. Can we use eap-gtc in windows xp without cisco wireless client adapter?

i installed cisco wireless client adapter software but still there isn't GTC protocol under PEAP properties.

thanks

Hi,

this is for wireless authentication right?

In that case you can use the default wireless utility that it comes with, i.e. with intel card, intel utility etc. They do have an option for GTC.

What is the version of Intel Supplicant?

Re: LDAP database without certificate

aksoyilker — Thu, 07 Jun 2007 13:43:48 GMT

intel pro wireless 2200BG

No not the Intel card model. I guess you do not have Intel supplicant. Search for Intel PRoset/wireless software on Google.

thanks a lot.

it is working with supplicant software.

must i install supplicant for non-cisco wireless cards to use eap-gtc?

Re: LDAP database without certificate

Yes Go for the card manufacturer's supplicant, they generally have the option for EAP-GTC.

If your issue is resolved, please mark this thread as resolved, so that others can benefit from it.

i want to ask a final question

why is PEAP-MSCHAPv2 incompatible with LDAP?

Re: LDAP database without certificate

Premdeep Banga — Sun, 10 Jun 2007 18:32:29 GMT

Hi,

Only answer would be, thats the way LDAP works, it cannot understand PEAP-MSCHAPv2
