Some of the objects in the eDirectory store have invalid timestamps and the timestamps must be fixed before migrating.
To workaround this issue perform the following procedure:
Configure NTP server using YaST and synchronize the time.
Run the ndsrepair -P -Ad command, select option 1 and then option 12 which repairs the timestamps and declares a new epoch.
Run ndsrepair -R
Run the ndsd restart command at /etc/init.d.
