Hello, today, when I was debugging some IdM issues, I noticed that some guids of of users in connected eDirectory systemc are looking quite interesting to me.

Some examples:

000BEEF84EF7D911B66EFFFFFFFFFFFF
000CB04C026EDF11B66FFFFFFFFFFFFF
000DD07A9AA8E011B66FFFFFFFFFFFFF
003FF47871FBDA11B66EFFFFFFFFFFFF
004053D4200FDF11B66FFFFFFFFFFFFF
0041925D0093DA11B41CFFFFFFFFFFFF


8D46DD53D77C5842FB918D46DD53D77C
8FC40D52AF87644EF6A88FC40D52AF87
9148C33457CFB04536839148C33457CF



I wonder, how exactly are guids created under the hood? Does those FFFFFFFFFFFFFs mean something special? Or is that just a padding to 32 bytes when migrated (probably, I dont know for sure) from older (netware?) system? Why the last 12 bytes repeat sometimes? But some users have guids fairly "ok-guid-looking-like" 809663B72F43D7118D4E00B0D0FE7592.
