I'm running into some problems when trying to add some alias entries and importing with ldapmodify or ldif2db. I'm using the directory server version 1.2.0.

Example of LDIF
dn: aliasedobjectname="ou=foo,dc=test,dc=com",ou=bar,ou=test,dc=com
changetype: add
objectClass: top
objectClass: alias

When I run this I get:
ldapmodify: Object class violation (65)
        additional info: single-valued attribute "aliasedObjectName" has multiple values

Same when I use ldif2db.. What am I doing wrong?
