Hi folks,                                        Thursday (15 July 1999)

Here's a quick update on SLP and LDAP:

- SLPv2 is now an IETF 'Proposed Standard' (RFC 2608, June 1999).
- LDAPv2 is now an IETF 'Draft Standard' (RFC 1777, March 1995).
- LDAPv3 is now an IETF 'Proposed Standard' (RFC 2251, December 1997).

(remember 'Draft' is a higher level than 'Proposed' in IETF specs)

James Kempf and Pete St. Pierre (both of Sun) have a new book out on
SLP system administration, 'Service Location Protocol for Enterprise
Networks' (available from Amazon, Barnes and Noble, etc).  According to
James Kempf, "the entire second half of the book discusses deploying,
configuring, and administering SLP networks.  The discussion is slanted
towards generic SLPv2, but much of it should apply to Novell NetWare 5's
implementation of SLPv1 as well."

James and Pete have also just issued a significant update of:
 
  "Conversion of LDAP Schemas to and from SLP Templates", 06/17/1999, 
  <draft-ietf-svrloc-template-conversion-04.txt>                        

In my next revision of the SLP 'printer:' template (for alignment with
the IPP/1.1 specs) I propose to write an LDAP schema translation of the
template (currently there is no standardized schema for printers in
LDAP-based directory systems).

All the SLP RFCs and I-Ds are listed below.  All the LDAP RFCs (but not
the several dozen I-Ds) are also listed below.  The LDAP protocol is
directly based on the DAP (Directory Access Protocol) specified in the
ITU-T X.500 series (also published as ISO 9594).  Authentication in LDAP
is based on X.509 'The Directory: Authentication Framework'.

Cheers,
