commit 956678685325a79a315f4ef19c0d834fd1747e4c
Author: Andrew Bartlett <abartlet at samba.org>
Date: Tue Aug 14 16:08:47 2012 +1000
s4-dsdb: Add mem_ctx argument to samdb_ntds_settings_dn
As this value is calculated new each time, we need to give it a context to live on.
If the value is the forced value during provision, a reference is taken.
This was responsible for the memory leak in the replication process. In the
example I was given, this DN appeared in memory 13596 times!
