Thanks for the tip. I changed the LDAP driver to M-Vault and appear to be
slightly further forward. The IDM trace now reads successfuly read schema
but the driver still returns unsuccesful and no classes appear available
in the schema mapping rule.

[06/21/07 15:36:26.765]: X500 ST: LDAP: Schema.Schema() Sucessfully read
schema from cn=subschema-subentry, o=testorg, c=GB
