how can radius pass authentication with wrong passwd?

Hi all,

i want to built a usergroup ,which all the users belong to it  don't  need
authenticate when they log in.i configure the database(mysql) like this:
table radcheck:
+----+----------------+----------------+------+----------+
| id   | username | Attribute    | op   |  Value  |
+----+----------------+----------------+------+----------+
|  8   | TEST07    | Password  | ==  |    8934 |
+----+----------------+----------------+------+-----------+

table radgroudcheck:
+----+----------------------+-------------------+------+-------+----------+
| id  | GroupName     | Attribute                | op    | Value |
+----+----------------------+---------------------------+--------+---------+

|  3  | test                 | Access-Accept     | :=     |    1     |
+----+----------------------+---------------------------+--------+---------+


table usergroup:
+---- +----------------+-------------------+
| id   | UserName | GroupName  |
+---- +----------------+-------------------+
| 28  | TEST07      | test             |
+----+-----------------+-------------------+

but it can't pass the test when i type the passwd is not 8934,why? thank you
very much.


best regards,
