There are three drafts regarding this protocol published, note however the
first two of them are a bit out of date. Hopefully there will be a new set of
drafts coming within the next month or so.
"Lightweight Directory Access Protocol (v3)",06/06/1996,
<draft-ietf-asid-ldapv3-protocol-01.txt>
"Lightweight Directory Access Protocol: Standard and Pilot Attribute
Definitions",06/06/1996, <draft-ietf-asid-ldapv3-attributes-01.txt>
"Lightweight Directory Access Protocol: Extensions for Dynamic Directory
Services",06/14/1996, <draft-ietf-asid-ldapv3ext-00.txt>
Internet drafts can be obtained from many sources such as

Hope this helps,
