From 0311a5396b1740c3a0f0cdde7a2e5da4be50d4bd Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Tue, 2 Jan 2007 03:39:01 +0000 Subject: r20459: LDB map cleanup: - Replace 'return 0' with return LDB_SUCCESS in more places. - Do not return NULL attribute values, these are not permitted. Instead, fail the whole conversion. - Cleanup old comments.
