No, smtpd(8) is merely the messenger, reporting the error that
trivial-rewrite(8) encountered, when trying to resolve a sender or
recipient address to a (user, transport, nexthop) triple. The mapping
that maps an address to a transport:nexthop MUST be single-valued.

You have failed to post the most important information required
to help you:
- the definition of the transport_maps LDAP table.
- LDIF form of the relevant attributes of the LDAP entry that
exhibits the problem.
- Other details per http://www.postfix.org/DEBUG_README.html#mail
