I've installed Joomla 3.4.4 (twice) with exactly the same outcome.
Problems: - when entering ANY information into the username and password field on the back end login page, the page refreshed back to the login page without any errors or warnings on the page or in the server logs. - the same for trying to login on the front end. - When visiting the site, below the site title and header image a message is displayed "Error: You are not authorised to view this resource."
Both after and before installing joomla I uploaded a .user.ini to turn off magic quotes. The configuration.php has correct settings for life site, session time out and a correct location for logs and temp files. I've verified that the logs and tmp directory are writeable from Joomla (added code to create and write to a file in both directories). I've checked all the modules and plugins in the database. I've set session_save_path to a location that is writeable. I've ruled out redirections from .htaccess. I've enabled all messages to be displayed. A valid cookie is sent to the browser and back to the site. The jos1 database contains the cookies sent to the browser The jos1 database has correct settings for both user and group
There was an warning about an unserializable object I've checked out. It's in Registry.php line 100:
public function __clone()
{
$this->data = unserialize(serialize($this->data));
}
When print_ring $this->data the following is shown:

)
and
��j Object
(
)
With both can be serialized but not be unserialized by PHP. I decided to comment out the line cloning the data. After this the 'Getting Started' article didn't give the error any more, but showed the article as normal. The names of the objects raise concern with me, I've never seen such names before in PHP When I print other variables. I for instance get Joomla\Register\Register Object
But this did not fix the login problem.
I'm pretty completely at a loss.
Edit:
In the database a session is created:

Nothing else seems to change. The jos1_users table has an lastvisit date and time set the the date and time of installing Joomla.
No new sessions are created in the database when trying to login multiple times.
With error reporting set to development nothing is reported when visiting and trying to login the administrator back end.
When visiting the site and a few seconds later trying to login the front end this is logged:

I also tried installing Drupal on the server to a different subdomain. The only thing it's able to display is these error/warnings. Again about serialization.

The service provider changed PHP to not use FCGI for our domain. This fixed the problem. Both the serialization problem has been fixed, as is the login problem.
