autofs wild cards

My auto.home has "* host:/export/&" for user directories. When I use the automount migration tool the * is changed to / and I get the error: adding new entry "cn=/,ou=auto.home,dc=domain,dc=com" ldapadd: Naming violation (64) additional info: value of naming attribute 'cn' is not present in entry Is there a way to get the wild card to work or do I need to enter each user instead of using a wild card? Thank you for your time.
