Do you reall want every user account on every service to have a
different username? (i.e. the user cannot request to be known as
'fred' on both the SMTP service and the IMAP service?

That depends on how you provide the services. If the network address
of the services used by domain-A users is different from that used by
domain-B users then the server processes will know which domain they
are serving.  If the same network address is used to serve all domains
then you do indeed require the uids to be unique across domains (but
you probably do want to let fred@x.y.com use that ID for all

You could do that if you are prepared to have one config line for each
service. Something like:

overlay unique
unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=SMTP)
unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=IMAP)
unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=POP3)
unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=XMPP)
unique_uri ldap:///ou=People,dc=org?uid?sub?(authorizedService=SSH)
