I have a ftp site with about 1000 users running vsftpd on Ubuntu 10.04 Server. I now need a more fine-grained rights management and the normal user,group,world is not sufficient anymore. Because of that I mounted my ext4 filesystem with POSIX Acls enabled. Is there an option I need to apply in the configuration so that vsftpd honors the acls? Or doesn't it event support them?
Vsftpd does not support them. This means it is not possible to modify the ACLs with a FTP client. But vsftpd has no other choice but to honor them, because the kernel prevents vsftpd to do anything, that is permitted by the ACLs.
