Hi,
I spend several time to find why when i created new companies program refused me password for the new companies.
I have found... after checking table _users, simply when you create a new company and not fill the new password, program doesn't copy your actual password, only your username and put automatically password as new password.
The solution will be to modifiy the program in /admin/create_coy.php to avoid this.
I don't have time to modify also i only put a new message to not forget to fill the password

At ligne 289 you will insert a new line:
display_note(_("When creating a new company, your password is not copied, new password is '<b>password</b>' by default "), 0, 0, "class='currentfg'");
