From af0163fdfc774f3a032610aadbc1203a770970dc Mon Sep 17 00:00:00 2001 From: Michael Adam Date: Wed, 1 Apr 2009 12:23:07 +0200 Subject: [PATCH] s3: fix the fix for bug #6195 - dont let smbd child processes panic This patch makes sure the original and temporary TDBs are closed _before_ the rename. Originally, the open TDB was renamed, and so the name passdb.tdb.tmp stayed around in the db context. Hence upon client connect, the smbd children died because reinit_after_fork() calling tdb_reopen_all() would try to reopen passdb.tdb.tmp which existed no longer...
