I believe WG consensus supports changing LDAP's
mandatory-to-implement "strong" authentication algorithm
from SASL/DIGEST-MD5 to StartTLS+simple(name/password).

Hence, I direct the Editor to make appropriate changes
to this draft to change the mandatory-to-implement
"strong" authentication mechanism to
StartTLS+simple(name/password).
