services.vsftpd.userDbPath

Only applies if enableVirtualUsers is true. Path pointing to the pam_userdb user database used by vsftpd to authenticate the virtual users.

This user list should be stored in the Berkeley DB database format.

To generate a new user database, create a text file, add your users using the following format:

user1
password1
user2
password2

You can then install pkgs.db to generate the Berkeley DB using

db_load -T -t hash -f logins.txt userDb.db

Caution: pam_userdb will automatically append a .db suffix to the filename you provide though this option. This option shouldn't include this filetype suffix.
