The "application" data in question is indeed the MIT KDC
implementation; all this stuff is internal to the MIT implementation.
In src/include/kdb.h you'll find definitions of some macros KRB5_TL_*
vaguely describing in their names what they're used for; for the
actual definitions of the layouts, you'll have to dig around in the
sources. At the moment, it's sort of a catch-all slot for holding
anything new we want to stick in there without having to redefine the
XDR types we use for database records (since the old DBM-style APIs
only give you "key" and "data" slots), stuff like that.
