+This directory contains a skeleton backend for ldb backends that allow
+using an LDAP server while mapping the attributes in that schema to
+another schema. This backend will never be used itself but instead have
+other backends based on it (e.g. ldb_samba3 for a Samba3-LDAP-to-samdb
+backend)
+
+Each backend that uses this skeleton has to specify an array of
+struct objectclass_mapping's (see ldb_map.h).
+
+If no mappings are defined for an objectclass, it will be kept as is.
+
+Special mapping routine for dn's (calls rdn mapping routine)

+Keep cache of mapped dn's so we don't have to traverse the tree each time
