Conversion of LDAP Schemas to and from SLP Templates

This document describes a procedure for mapping between Service Location Protocol (SLP) service advertisements and lightweight directory access protocol (LDAP) descriptions of services. The document covers two aspects of the mapping. One aspect is mapping between SLP service type templates and LDAP directory schema. Because the SLP service type template grammar is relatively simple, mapping from service type templates to LDAP types is straightforward. Mapping in the other direction is straightforward if the attributes are restricted to use just a few of the syntaxes defined in RFC 2252. If arbitrary ASN.1 types occur in the schema, then the mapping is more complex and may even be impossible. The second aspect is representation of service information in an LDAP directory. The recommended representation simplifies interoperability with SLP by allowing SLP directory agents to backend into LDAP directory servers. The resulting system allows service advertisements to propagate easily between SLP and LDAP.
