I don't think that there is any explicit limit on PAC length. Since the
length field for the PAC components and even for the full PAC TLV is
using 2 octets, the PAC could, in theory, be up to 64 KB. In other
words, authentication server could generate a very long PAC-Opaque, but
I would be quite surprised if this were to be increased much over 500
bytes due to PAC-Opaque being sent as part of the tunnel establishment.
