I've just installed Wing FTP 4.2.0 on Solaris 11.1, wrote the LD_LIBRARY_PATH_ variables in /etc/profiles, and start the server.
I see in [installDIR]/Data/_ADMINISTRATOR/admins.xml the correct username and a hashed password, but in web UI and also in wftpconsole, I got an error message: Login failed! when I tried to log in with this user.
I reinstalled wftpserver 3 times (with new passwords), but it wasn't any difference.
 Tue, 11 Jun 2013 10:10:56 administrator 'admin'(IP:192.168.xxx.xxx) login failed!
I googled and also searched this forum after solution, but found nothing relevant.
Thanks all for your help
