It does not matter the version of openmeetings. I tried to restore 2.1.0 backup
to 3.0.7, and to 2.1.0 (the same version which produced backup file).
The case of this error was the state_id in address in user definition.
If state_id is not in predefined list of state ids - import fails.
As I understand state for ldap users is taken from Active Directory field
(which can be empty or contain any string), and openmeetings creates new
state_id with new state name if no-one was matched.
As a result importing backup constantly fails until I fixed state_id to one of
predefined (update om_user set state_id=221).
I guess at least error in this case can be more informative.
