I have set up a new Pro server. Virtual servers added to it are set up with SFTP by default. This works.
I just migrated a bunch of domains from an older (but updated and current) Pro server that used FTPS by default. I can access these domains on the new server via plain FTP and FTPS, but I cannot access them via SFTP.
If I try and set up an SFTP jail for a migrated domain, nothing FTP-related works at all. The logs in Filezilla appear to imply that the user name and password are wrong, but I reset the password through Edit Virtual Server -> Configurable settings and this changes nothing. There is no way to change the password at Edit Users.
Simply put, I was delighted when I found that Virtualmin's implementation of SFTP worked properly on the new server, but it's broken on migrated domains, and trying to fix it on a migrated domain completely borks all FTP-like access. I want to figure out how to do it, or do it properly.
