ProFTPD multiple users with super user

I have a question on ProFTPD. Is it possible to create a super user that can access all other ftp users ftp home directory?

For example, say we have SuperUser, user1, user2, user3, the user home directories is contained inside the SuperUser home directory

/home/SuperUser/
/home/SuperUser/user1
/home/SuperUser/user2
/home/SuperUser/user3

Now, SuperUser can access everything inside /home/SuperUser/ but is jail locked to this directory. and user1, user2, user3 are all jail locked to
user1 - /home/SuperUser/user1
user2 - /home/SuperUser/user2
user3 - /home/SuperUser/user3

I know you can jail lock all users by modifying /etc/proftpd/proftpd.conf and changing this line

# Use this to jail all users in their homes
DefaultRoot                     ~

I already have 1 user that should access everything and my ftp connection works fine, but my secondary user, whose home directory is inside the first users home directory cannot use FTP

From the ftp client (FileZilla) I get this error when logging in with this user

Response:   550 PWD: Permission denied
Error:  Failed to retrieve directory listing

If I move the home directory to /home (default option) then it works but my super user cannot access those files.

Can this be done?

Got it working.

I played with the configuration a bit an had to change the normal users file ownership to the user and SuperUser, then in the proftpd configuration for each user, in /etc/proftpd/conf.d/user.conf I had to allow both the normal user and the SuperUser to access that directory

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
