Perfect,
You resolv my problems.
The first step OK :
Web Interface -> Users -> List ALL Users -> fog -> Change password
The second point OK :
Edit the file /var/www/fog/lib/fog/config.class.php:
nano /var/www/fog/lib/fog/config.class.php
define (‘DATABASE_PASSWORD’, “MdpROOTsql”);
The FOG server is still functional in the Web and the database requires a password to enter!
Everything is good for this open ticket. I thank you for the efficiency of your response.
Continue like this.
Best regards.
