I have two machines with the same users, I need to do an ssh without a password between them, I have two users medya and orainst
medya home is / home / medya / orainst home is / tools / appsw / oracle / orainst
I set a password for both of them (yes, I swear I made all permissions, religiously).
it works for any user in regular home directories (medya), but not for orainst.
and the strangest thing is, if I started the ssh server in debug mode, it works fine for both users.
here is a log for both ssh starting with service and ssh starting with debugging
here it fails:
