Yes: "sn" is MUST in "person", which "qmailUser" is derived from.
According to <draft-ietf-ldapbis-models>, derived objectClasses may turn
MAY attributes into "MUST" attributes, but "MUST" attributes of ancestor
classes cannot be turned into "MAY" by a descendant class. So, as far
as I understand the specifications, the above objectClass definition for
"qmailUser" is malformed, i.e. "cn" and "sn" cannot be "MAY" since
they're already "MUST" in "person".
By no means this indicates a software issue with OpenLDAP, so this ITS
will be closed.
