IAS, 802.1 auth and EAP

Hi,

I have a working wireless Lan with an IAS aerver backend. I can verify
WEP client auth once the link is established just after client logon,
and dynamic IP assignment. However I cannot verify if EAP is satisfied
through IAS - so

0) how I access the IAS log events ?
1) how can I verify my Wireless AP is effectively authenticatiing
against IAS ?
2) how can I trace the TLS session in order to check if everyting is
done ?

Best regards,

Carlos
