Can't get the automatic Index to work with OrientDB Server v2.0-M2

[Bretto]

CREATE CLASS User extends OUser
CREATE PROPERTY User.id STRING
CREATE INDEX User.id UNIQUE
insert into User set name = 'visitor', status = 'ACTIVE', password = 'visitor', roles = [#4:3]
select from User

----+-----+-------+------+--------+-----
#   |@RID |name   |status|password|roles
----+-----+-------+------+--------+-----
0   |#15:0|visitor|ACTIVE|visitor |[1]
----+-----+-------+------+--------+-----

select from index:User.id
0 item(s) found. Query executed in 0.001 sec(s).

The property id is empty, and no index was created, is this a bug ? I am trying to get an automatic generated Unique "id" associated with User.

The property id is empty because you didn't insert one.

In OrientDB, each record has an auto assigned Unique ID

You don't have to worry about that, the column @Rid is already unique.
(you can read more about it here and here.

Yes but have a look at this question,
#3137
The @Rid is changing... I need a unique and persistent value, do you have any recommendation ?
