I also have this problem, thanks for answer you helped me that I new where to search.
I have one portal and I included this super duper feng office in it. When I add new user to a portal, he has the same password like on fengoffice.
Code to generate password for feng office:
First you have to calculate value for field token in users table then calculate users password from token at the end insert all values in to a table.
Example:
<?
$salt = substr(sha1(uniqid(rand(), true)), rand(0, 25), 13);
$input_password = "mypassword";
$token = sha1($salt. $input_password);
INSERT INTO `og_users` (`id`, `company_id`, `personal_project_id`, `username`, `email`, `token`, `salt` ) VALUES
(1, 1, 1, 'test_user', 'email@gmail.com', '$token', '$token')
?>
I hope I helped you someone who search for this question!
