Further to this query and to provide a little background.

I am testing certificate based authentication with ASA clientless/client
SSL VPN with an IOS CA Server being used for PKI.

I have defined the the IOS CA as a trustpoint on the ASA and issued the ASA
with an identity certificate. On a Windows client I have installed the IOS
CA certificate and then used the Cisco IPSec VPN client to create a CSR
which I submitted via the terminal/CLI on the IOS CA to be issued with an
identity certificate for the Windows box.

After trying many things I simply could not get the client to authenticate
to the ASA using the certificate from the IOS CA. On the client I kept
getting the "Certificate Validation Failure" error and in the debugs on the
ASA the most meaningful entry was this:

Tunnel Group: tg1, Client Cert Auth Failed!
Embedded CA Server not enabled. Logging out the user.

I read on the Cisco support forums that someone else had an issue somewhat
similar and was told by TAC the IPSec VPN client made a CSR suitable for a
certificate for IPSec but not SSL VPN. After reading this, and knowing that
I had used the IPSec Client to create by CSR I added a new trustpoint for a
my Microsoft CA on the ASA and authenticated the MS CA on the ASA. Using
the web-interface for the MS CA, I then enrolled with the MS CA on the
Windows client and received a certificate from it. I was then able to
instantly authenticate with the ASA now I was using the MS CA as a
trustpoint on the ASA and had been issued with a certificate from that same
MS CA on the Windows client.

So, after that rather long winded explanation, I come back to my initial
query. Considering I have had the issues mentioned above which was resolved
by enrolling with another (MS) CA, is there another method I can use,
preferably like the web interface for the MS CA, or like the 'user-db'
function on the ASA, to enrol a client machine with an IOS CA instead of
doing what I did and use the IPSec VPN client to make a CSR and then
copy-paste it into the IOS CA?

Thanks
Ben
