Hi Andrew: We have finished our investigation on your question regarding prefixMap appearing on the wire.
PrefixMap is an attribute specific to Microsoft's Active Directory implementation. It is used by the system to map an internal structure to its corresponding OID. PrefixMap resides in the directory and, as a consequence, can be retrieved via LDAP by using any LDAP-capable tool such as LDP or LDIFDE. PrefixMap does not appear on wire for any LDAP protocol related messages. Microsoft LDAP implementation do not access or use the attribute over wire. It only appears on the wire when explicitly requested. Please let me know if this answers your question. If yes, I'll consider this issue resolved.

However, it is exposed over LDAP, and I don't see a description of it's format in MS-ADTS. With ldp I see only: 'binary blob'. With ldbsearch, I see: bin/ldbsearch -H ldap://win2k3-2.ad.naomi.abartlet.net -s base -b CN=Schema,CN=Configuration,DC=ad,DC=naomi,DC=abartlet,DC=net -Uadministrator prefixMap # record 1 dn: CN=Schema,CN=Configuration,DC=ad,DC=naomi,DC=abartlet,DC=net prefixMap:: BwAAAFkAAADUEQcAKoZIikEBBcsTCAAqhkiB/xcBBbZuCAAqhkiBzBEBBVBvCAAqhk iCugUBBesFCAAqhkiB8xcBBZQGBwAqhkiJHQEFzwYHACqGSNMFAQU= (and our --show-binary option does not know how to parse this). It was in the past assumed that this attribute was not available over LDAP, but as it is, could you please describe the format?
