does the unique overlay support checking multiple values for a single uniqueness check? Our clients can use emails in two attributes (think mail and mailAlias) and addresses have to be unique in regard to both fields, which means an address that is used in either of them cannot be used in any other of them. Is that possible?

slapo-unique(5) plus slapo-constraint(5)

IMHO this does not work without adding all possible values to at least one of the attributes *or* SUP-ing all attribute values from a common attribute type.
