From 3e2c696e45b24b0192ab7b1ddaf1dd4d79571609 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Sun, 24 Sep 2006 02:49:04 +0000 Subject: r18866: Jeremy and Volker have given the go-ahead on the group mapping ldb code. Yay! This first commit copies lib/ldb/ from Samba4. A huge congratulations should go to Simo on this - he has put an enormous amount of work into ldb, and it's great to see it go into the Samba3 tree.
