From 9381a78c391bcccd5eddc159a5d3a3e12d19fde3 Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Mon, 27 Oct 2008 13:32:23 +1100 Subject: Use ldb_dn_from_ldb_val to avoid possible over-run of the value. The ldb_val is length-limited, and while normally NULL terminated, this avoids the chance that this particular value might not be, as well as avoiding a cast.
