From abe9ac53f0d240a867d499f184866603143756cf Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Mon, 29 Nov 2010 14:10:26 +1100 Subject: s4-ldapcmp: make ldapcmp a samba-tool command The ldapcmp tool is very useful, and should be available to Samba admins, not just developers. This makes it a samba-tool command, which also gives it the nicer command line handling that samba-tool has --- source4/scripting/python/samba/netcmd/__init__.py | 2 + source4/scripting/python/samba/netcmd/ldapcmp.py | 830 ++++++++++++++++++++++ 2 files changed, 832 insertions(+) create mode 100755 source4/scripting/python/samba/netcmd/ldapcmp.py (limited to 'source4/scripting/python') diff --git a/source4/scripting/python/samba/netcmd/__init__.py b/source4/scripting/python/samba/netcmd/__init__.py index d47b39dced..5a6a68cd29 100644 --- a/source4/scripting/python/samba/netcmd/__init__.py +++ b/source4/scripting/python/samba/netcmd/__init__.py @@ -172,3 +172,5 @@ from samba.netcmd.drs import cmd_drs commands["drs"] = cmd_drs() from samba.netcmd.gpo import cmd_gpo commands["gpo2"] = cmd_gpo() +from samba.netcmd.ldapcmp import cmd_ldapcmp +commands["ldapcmp"] = cmd_ldapcmp() diff --git a/source4/scripting/python/samba/netcmd/ldapcmp.py b/source4/scripting/python/samba/netcmd/ldapcmp.py new file mode 100755 index 0000000000..8bb1c8a8c7 --- /dev/null +++ b/source4/scripting/python/samba/netcmd/ldapcmp.py @@ -0,0 +1,830 @@ +#!/usr/bin/env python +# +# Unix SMB/CIFS implementation. +# A command to compare differences of objects and attributes between +# two LDAP servers both running at the same time.
