Are you trying to use unauthenticated or authenticated provisioning for

This is the expected behavior of unauthenticated (anonymous)
provisioning in EAP-FAST. The authentication server is supposed to
reject the provisioning phase and once the provisioned PAC is used in
the next attempt (i.e., the first real authentication), the server can
then accept the connection.

This all looks correct. The next connection attempt should then use the
provisioned PAC from /tmp/wpa_supplicant.eap-fast-pac.
