Date index for Apr 2002

hello 

I installed achievo on my computer to test it. I created an employee,
data in the database are present.

+----------+------------+------+-------------+----------------------------------+--------+-------+--------+
| userid   | supervisor | name | email      
|password                         | status | theme | entity |
+----------+------------+------+-------------+----------------------------------+--------+-------+--------+
| 1        | 0          | test | test dot 
|098f6bcd4621d373cade4e832627b4f6 | active | NULL  |      2 |
+----------+------------+------+-------------+----------------------------------+--------+-------+--------+

But I can't log in with this user.
No error message supplied and the login popup is redisplayed.
The only way to login is to use the administrator account.

If someone has an idea, don't hesitate :)

Thx
Nico
