[Proftpd-user] Issue configuring ProFTPd

Hello,

I am trying to configure ProFTPd v1.3.6e on CentOS 8 (actually 
replicating older configs from earlier versions of ProFTPd).

I have already earlier versions of ProFTPd running on CentOS 6 and 
CentOS 7 for a long time without issues, but this time I am having a 
hard time.

It's an installation with ldap-based authentication (using mod_ldap), 
and other modules.

Users logging in are forced to uid:gid of wftpuser:nginx (see list below).

LDAP-based authentication works but I am having several problems. When 
connected to the FTP Server using account abc, I cannot download files 
from it, despite everything seems OK (ownerships & permissions).

In fact, I can upload / create files & directories, but I cannot 
download (or delete or change) anything on the server: I am getting the 
message "No such file or directory)"!

Here is the listing of the account home dir (a typical Wordpress 
installation):

If I attempt to download e.g. license.txt, I am getting the message "No 
such file or directory"!

(Note: In all listings below, I have changed the real public IP address 
of the server to 10.10.10.30.)

The FTP client (FileZilla) shows:

    Status:    Starting download of /license.txt
    Command:     CWD /
    Response:    250 CWD command successful
    Command:     TYPE A
    Response:    200 Type set to A
    Command:     PASV
    Response:    227 Entering Passive Mode (10,10,10,30,238,59).
    Command:     RETR license.txt
    Response:    550 license.txt: No such file or directory
    Error:     Critical file transfer error

Here is the output regarding this failed transfer from trace.log (Level 10)

Could anyone please suggest any cause and solution for this issue? It is 
driving me insane!

Thank you in advance.

All the best,
Nick
