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