RE: A web of directories

["Bob Jueneman" <BJUENEMAN@xxxxxxxxxx>]

Phillip,

Please pardon my ignorance regarding DNS, but perhaps you could answer some questions:

1.  How widely is the SRV function deployed?  Is it standardized (RFC ?), what vendors support it, etc., etc?

2.  Can the SRV deal with multiple protocols?  If it doesn't already, could it be extended? In particular, for what I am trying to do to implement a web of directories, I would like to supply a DNS name for a directory, and allow the clients to find out and/or negotiate what directory access protocol they use, e.g., LDAP, DAP, NDAP (NDS), HTTP, FTP, or whatever.   Would this work?

Steve,

	That is exactly what the SRV record that I have been going 
on about for a year now does.

	It was deployed in the Vixie BIND code about 3 years back.
