Good detective work!  Though the bug isn’t for ADU, you took the implication
of the bug and applied it to ADU.  Thinking like a CCIE J

Hi Guys!

 

I discover whats happened! I'm running in this bug:

 

 CSCsk59988 

EAP-FAST [ TLS ] does not work for Cross forest user authentication. 

Symptom    Occurs when doing EAP-FAST authentication with the CSSC client. 

Conditions     <http://www.cisco.com/en/US/i/templates/blank.gif> Client is
sends inner-identity without domain markup. 

Workaround     <http://www.cisco.com/en/US/i/templates/blank.gif> This is
not a bug since CSSC can be customized to send inner-identity in UPN format.

 

My ADU isn't configured to validate the Server certificate and don't send
the domain. When I set this option it work fine:

 

Validate Server Identity: Enable

Trust Root Certificate Authority: <Any>

Select a Certificate: User1 Certificate.

Server/Domain: proctorlabs.com

Login Name: User1 

 

Without Validade Server Identity the Server/Domain box remain grey and
disable!

 

Thanks for the replies again!

 

Best Regards,

 

Yuri

Hi Guys,

 

Thanks for the replies.

 

So, I did some tests and still can't make it to works:

 

1) Enabled Require client certificate for provisioning: Don't Work

LOG: EAP_TLS Type not configured

 

2) Disable EAP-GTC and EAP-MSCHAPv2: Don't Work and I had to disable
Anonymous PAC provisioning.

LOG: EAP-TLS or PEAP authentication failed during SSL handshake

 

3) Create a static user in ACS Database with Password Authentication "ACS
Internal Database": Don't Work

LOG: EAP_TLS Type not configured

 

4) Create a static user in ACS Database with Password Authentication
"Windows Database": Don't Work

LOG: EAP_TLS Type not configured

 

Just for clarify, this certificate is working fine, because I tested it with
EAP-TLS and PEAP.

 

Any another idea?

 

Best Regards,

 

Yuri
