this related this post, find of config. ldap user mapped database user table , entry created fine. userdetails tries authorities main user class resulting in following exception:

edit
finally figured out!
in userdetails class extending own user class:
import package.user class mdtuserdetails extends user { instead needed extend springsecurity user class here :
import org.springframework.security.core.userdetails.user i believe causing transient object exception, answer suggested need have belongsto, etc. did have on classes.
caused transientobjectexception: object references unsaved transient instance - save transient instance before flushing: package.user this message tells user object want save contains @ least 1 reference domain object isn't saved.
according user class unsaved reference report or invoice object. have following options solve issue:
save reports , invoices manually before adding them user
or
enable automatic cascading of reports , invoices using
static mapping = { reports cascade: 'all-delete-orphan' reports invoices: 'all-delete-orphan' } or
add belongsto relationship invoice , report:
static belongsto = [user: user]
