UseFtpUsers option errors with pure-ftpd 1.0.49
Whilst installing ISPConfig on CentOS 8 I noticed that pure-ftpd 1.0.49 is choking on this line:
install/tpl/fedora_pureftpd_conf.master:UseFtpUsers no
UseFtpUsers seems to be deprecated and pure-ftpd 1.0.49 (if not even prior versions) have removed this option.
