r4867: Removing smbldap-tools from the svn tree. I'll include
the latest version in the actual release tarballs. Have spoken to the idealx developers about this. Updated README to reflect the changte for people using svn. Removed ldapsync.pl since it is no longer needed when using the smbldap-tools (only keep things you support). (This used to be commit f745e5119f420d4826ac395037880666761e05e8)
