commit 436d8b6e06c555b2f3dabad8218f08b713e7664c
Author: Andrew Bartlett <abartlet at samba.org>
Date: Tue Aug 25 16:27:20 2009 +1000
s4:python Fix the reprovision test by deleting 'deleted' objects too.
We were failing because CN=Deleted Objects, which is marked as
'deleted' itself, could not be re-added in a reprovision.

commit 6542a084a5dee239866f7d327c47afe2fc3efc6a
Author: Andrew Bartlett <abartlet at samba.org>
Date: Tue Aug 25 16:25:55 2009 +1000
s4:dsdb Rework show_deleted module not to liniearise the LDAP filter
Instead, use the fact that the ldb_parse_tree structure is public to
construct the 'and not deleted' clause as a structure, and apply each
filter tree to that template.
