I have a Ubuntu server with 3 user accounts (root, user1, user2). user1 has access via WinSCP, scp and ssh. No problems here. Then I've created another user2 but with this user I can't access the server via WinSCP but scp and ssh through console works like a charm. WinSCP says that authentication fails but I'm 100% sure that I have made no typo (I can say this after 433245 retries). Now I'm trying to find the differences between the two user accounts and the only differences are their username, password and user2 is in the sudoers group.
Any suggestions what else I can try?
