* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* This example sends the following CURL request:

* 	curl -X POST -k https://auth-sandbox.connect.abnamro.com:8443/as/token.oauth2 \
* 	-v \
* 	--cert TPPCertificate.crt \
* 	--key TPPprivateKey.key \
* 	-H 'Cache-Control: no-cache' \
* 	-H 'Content-Type: application/x-www-form-urlencoded' \
