I had a problem when configure user policy at my vsftpd server...
My user policy is like this :
- User A : at own home directory had sub folder A1 and A2
- User B : at own home directory had sub folder B1 and B2
- User C : have an access read privillage at folder A1 and B1
- User D : have an access read privillage at folder A2 and B2
For user A and B, its work.. but i got a problem to manage user C and D.
How i can set that policy user like that? plz... give me advice or reference bout that?
First time .. i used symbolic link (ln) to do that, but it's not work when i access my ftp from ftp browser such as firefox. From firefox seen that seen like a file ln, not a sub folder.
Thank you

give A1 and A2 a group, give groups whatever permissions:
give B1 and B2 a group, ditto
give A1 and B1 a group, ditto
give A2 and B2 a group, ditto.

thats what the chmod 777 or rwxrwxrwx is all about
user - group - everyone
and folders can have multiple groups... is this what you're looking for?

Its work just for directory listing. but i need a way to costumize (seems like that) on vsftpd. As I know, the group for handling user right policy only ftp group.
With your explanation, howto set that costumizing group can make its work at vsftpd ??
