| ~ "suffixmassage" translating to "ou=Users,dc=wfu,dc=edu"

Things to try:
- -Berkeley db>=126.96.36.199
- -ensure you have a checkpoint setting in your database definition in
If you plan to never restore slave LDAP db's from backups, turn off
transaction loggin on the slave via the DB_CONFIG (and instead, ensure
you are treating your transaction logs on the master very well).
