The edtFTPD server is running on Windows XP, it was installed into c:\edtftpd\ directory.
After default installation and after changing the 513->544 in the passwd file I found another issue:
Only the users belonging into Administrators group can access the c:\edtftpd\ directory and its subdirectories, so as a result all ftp users have to be members of Administrators group. Users that do not belong to Administrators group are not allowed to log-in (error 530).
Of course I can change access rights to c:\edtftpd\ to "Everyone" group, however doesn't this impose some security risks ?
