DESCRIPTION
Virtual users is a simple mechanism to store a list of users, with their password, name, uid, directory, etc. It's just like /etc/passwd.
But it's not /etc/passwd. It's a different file, only for FTP.
It means that you can easily create FTP-only accounts without messing your system accounts.
Additionnaly, virtual users files can store individual quotas, ratios, bandwidth, etc. System accounts can't do this.
Thousands of virtual users can share the same system user, as long as they all are chrooted, and they have their own home directory.
FILES
/etc/pure-ftpd/pureftpd.passwd
/etc/pure-ftpd/pureftpd.pdb
ENVIRONMENT VARIABLES
PURE_PASSWDFILE If this variable is defined, this is the default value for the text password file. Without this variable, /etc/pure-
ftpd/pureftpd.passwd is assumed.
PURE_DBFILE If this variable is defined, this is the default value for the PureDB password file. Without this variable, /etc/pure-
ftpd/pureftpd.pdb is assumed.
