Permissions+default directory in openssh on ubuntu

I have a pretty basic ubuntu system running in a vm to do open-ssh.  By default each user that gets in via sftp goes to /home/username.  I need to change a user to go to a different directory when logging in.  Note that this user has no password, just a private key (so its authenticating with username+private key).  I need the user bob to default to the /home/homer directory.  I change this by nano /etc/passwd and changing the default but then when user chuck tries to login it doesnt work - says server refused our connection, change it back to /home/bob and it works fine.  Bob does have all access to /home/homeward...he can write files to that directory, change to that directory, and delete files from the directory so not sure why he cant go to that directory by default.
Using winscp to connect (windows machine) and you can specify the local and remote directories - doing this WILL work and allow him to "default" into the /home/homer directory, but I think winscp just logs in then changes directories for him right away (instead of the actual server putting him in that folder which is what I need).
Thoughts?
I tried doing it via a group too - still no luck

Sftp is part of ssh and is directing the user to their home directory by default.

You could use usermod to alter the home directory thus altering where the user will end up upon logon.
I think winscp includes the option to specify the path /home/homeward rather than relying on the default.

Not clear which point from my comment you want addressed in this response.
usermod -d /home/homeward homer
this will also affect the users ssh login which will now get them started at /home/homeward ( you could use .login, .profile, .bash_profile .bashrc to cd to a different directory) but cd ~homer wil always go to where the home directory is pointing within passwd.

I think winscp has the option prior to the connection for the specification of the remote directory which you could use /home/homeward

Are You Ready for GDPR?

With the GDPR deadline set for May 25, 2018, many organizations are ill-prepared due to uncertainty about the criteria for compliance. According to a recent WatchGuard survey, a staggering 37% of respondents don't even know if their organization needs to comply with GDPR. Do you?

Still get the same thing "server refused our key" - that is the winscp error I get anytime I try to change the user homer to get into /home/homeward

Seems like no matter what I do with usermod -d or editing the /etc/passwd to change the path of the user, I cannot login with the user unless its set to his default /home/homer.  As mentioned earlier - login with username and a key file - the key file has nothing to do with the location right, its just for authentication purposes - just strange that as soon as I change the directory it fails as if its an auth issue.  And again, once logged in I CAN access these directories I am trying to have the user land in by default

server refused our key
authentication failed is the error I get

Ran across this article which solved my issue.  The default is store the key in an encrypted (hidden) folder (.ssh) so moving that elsewhere did the trick.
