The new text clears up the confusion. Before, it sounded as at least
CRAM-MD5 could be implemented with MD5 encoded password stoarge. I
suppose if LDAP could store passwords in CRAM-MD5 format (whatever
that is) then this goal would be achievable. Reading slapd.conf(5),
it seems LDAP can only store {SSHA}, {SHA}, {SMD5}, {MD5}, {CRYPT},
and {CLEARTEXT}. It's probably in the RFC, and CRAM-MD5 is missing
from the list.

How sad.
