[afnog] Cisco ACS Release 3.2(3) Build 11

[John Gitau]

Okay Im stuck here:

I have been recently been checking on ways of deploying Identity Based
Networking Services using a CiscoSecure ACS 3.2(3) for a wired LAN.
Everything was going very well untill I introduced a backend database
for it to pick the users from. The backend just happens to be microsoft
active directory.

My main problem right now is I have not managed to get a certificate to
work on the ACS at all ie I can't install a certificate on the ACS. I've
followed the procedure listed here:
<http://www.cisco.com/en/US/products/sw/secursw/ps5338/products_user_gui
de_chapter09186a008023361c.html#wp97987> to the letter. I even get the
message telling me that all went well and it has been installed, but for
some reason every time I enable "Allow EAP-MSCHAPv2", or anything that
requires to use the said certificate, I get the error "Failed to
initialize PEAP or EAP-TLS authentication protocol because ACS
certificate is not installed.". I am uploading the certificates in
DER-encoded binary X.509 v3 format. The private key has a .key
extension. 
Ie :
Certificate file is XXXXXXXXXXXxx.cer
Private key file is XXXXXXXXXXXxx.key

!* I have tried other extensions but I get errors like unknown format
for *.pem and *.pvk

So my question is: Is there a specific way or format to upload this
certificates to the ACS? Does anyone have any pointers in the right
direction for deploying 802.1x authentication using a CiscoSecureACS
solution with Windows AD as the backend "database".
