40 * IceSetPaAuthData is not a standard part of ICElib, it is specific
41 * to the sample implementation.
42 *
43 * For the client that initiates a Protocol Setup, we look in the
44 * .ICEauthority file to get authentication data.
45 *
46 * For the client accepting the Protocol Setup, we get the data
47 * from an in-memory database of authentication data (set by the
48 * application calling IceSetPaAuthData).  We have to get the data
49 * from memory because getting it directly from the .ICEauthority
50 * file is not secure - someone can just modify the contents of the
51 * .ICEauthority file behind our back.
