Ive just tried to migrate some users to a new linux machine. Target is a scientific Linux 7 and source is an older Suse Linux. The copied hashes in /etc/shadow are not working in SL7. Previously I've already managed to migrate user accounts that way, but never to Scientific Linux. Maybe they limit the hash functions by default and there is a switch to turn on older hashing methods somewhere, but I dont know where to start to look.
So any hint where to investigate further is appreciated.
