More clues...

Because it bugs me (yes, pun intended), I played some more with
the sample DUID

This unpacks into hex  '010000000001000114ea1b240800272a9882'

Working backwards, I believe it represents:

 01000000 0001 0001 14ea1b24 08:00:27:2a:98:82

Where 01000000 is the client IAID -- unfortunately in native, not
network order.
This makes it impossible to maintain lease files if a server's
endianness changes
in an upgrade.  Seems like a bug.

Then 0001 would be the DUID type (LLT), 0001 would be the HWtype (ethernet),
14ea1b24  would be sun, 13 Feb 2011 04:31:32 GMT - which is close enough
to the
other times in the sample lease file to be credible.

And 08:00:27:2a:98:82 seems like a reasonable ethernet link address.

Digging through the code, this analysis seems to be correct.

I'll file the bugs.

I still would appreciate some lease files that I can use for test data...
