The PAC file format used by Cisco is not supported in wpa_supplicant
since there does not seem to be any public documentation describing the
used format.

You would need to convert the PAC file to format supported by
wpa_supplicant for this off-line provisioning to work.. Which is going
to be a bit complex operation unless you have access to specification of
the Cisco format. However, if you are fine using in-band provisioning of
the PAC, that should work fine with Cisco ACS.
