I upgrade from NSD 7.03 appliance to NSD 7.1 .
The installation and conversion went fine everything OK
The day after the LDAP scheduled ran, the import deleted every users,
managers, technicians
Now no login available except for the admin and testing LDAP shows 0 users
for all roles.

no parameter was changed in LDAP configuration
i tried deleting nsd role/group and adding users with no luck

Please help.
Thank You
