From cc146adb2635daa4625ec00fc1c2e4ae757e72f9 Mon Sep 17 00:00:00 2001 From: Volker Lendecke Date: Mon, 27 Sep 2004 14:44:07 +0000 Subject: r2691: Increase a debug level for a quite frequent operation. Optimization for 'idmap backend = ldap': When asking sid2id for the wrong type, don't ask ldap when we have the opposite mapping in the local tdb.
