From 134d3c1986f2eba141b39acd2107aec104472ea9 Mon Sep 17 00:00:00 2001 From: Fraser Tweedale Date: Thu, 31 Mar 2016 15:37:51 +1100 Subject: [PATCH 91/97] Lightweight CAs: extract LDAP commit/delete methods LDAP code to add, modify and delete authority entries exists in multiple places. Extract these methods to remove this duplication and provide a cleaner basis for upcoming implementation of replication handling.
