Assuming your naming context is "dc=mvista,dc=com",
with a recent devel snapshot you can do:

database ldap
uri ldap://this.host
suffix "l=California,ou=Engineering,ou=People,dc=mvista,dc=com"
suffixmassage "l=California,ou=Engineering,ou=People,dc=mvista,dc=com"
    "ou=Engineering,l=California,ou=People,dc=mvista,dc=com"
# acls and so ...

database ldbm
suffix "dc=mvista,dc=com"
# store real data under
"ou=Engineering,l=California,ou=People,dc=mvista,dc=com"
# other directives ...

This rewrites the naming context of the requests as well as that
of the results to make them appear as if they were stored as
    "l=California,ou=Engineering,ou=People,dc=mvista,dc=com"
while they are actually stored as
    "ou=Engineering,l=California,ou=People,dc=mvista,dc=com"

Otherwise all you can do is:

database ldbm
suffixalias "l=California,ou=Engineering,ou=People,dc=mvista,dc=com"
    "ou=Engineering,l=California,ou=People,dc=mvista,dc=com"
suffix "l=California,ou=Engineering,ou=People,dc=mvista,dc=com"
suffix "dc=mvista,dc=com"
# store real data under
"ou=Engineering,l=California,ou=People,dc=mvista,dc=com"
# other directives ...

This will make searches with base
    "l=California,ou=Engineering,ou=People,dc=mvista,dc=com"
succeed, but results will have naming context
    "ou=Engineering,l=California,ou=People,dc=mvista,dc=com"
