Alter User Inside procedure

Question

Hi to all,
I have a user named dbo and vijay.
I have a procedure under dbo named as sp_alteruser
CREATE OR REPLACE PROCEDURE DBO.SP_ALTERUSER
P_USER_ID IN VARCHAR2,P_PASSWORD IN VARCHAR2,P_MSG OUT VARCHAR2)
--Declaration of IN parameters
IS
E_PASSWORD EXCEPTION;
E_INVALIDUSER EXCEPTION;
PRAGMA EXCEPTION_INIT(E_PASSWORD,-00988);
PRAGMA EXCEPTION_INIT(E_INVALIDUSER,-01918);
BEGIN
DECLARE
V_COUNT NUMBER;
V_STATEMENT1 VARCHAR2(200);
BEGIN
--To check whether the user has been already exists
SELECT COUNT(*) INTO V_COUNT
FROM ALL_USERS
WHERE USERNAME = P_USER_ID;
IF V_Count = 0 THEN
--If the count is 0 means that the user does not exist
DBMS_OUTPUT.PUT_LINE('User Does Not exist');
END IF;
IF V_COUNT>0 THEN
--If the count is greater than 0 then the Alter statement is executed
V_STATEMENT1:= 'ALTER USER ' ||P_USER_ID||' IDENTIFIED BY '
||P_PASSWORD;
     -- EXECUTE IMMEDIATE 'GRANT ALTER USER TO VIJAY';
-- EXECUTE IMMEDIATE 'ALTER USER ' ||P_USER_ID||' IDENTIFIED BY ' ||P_PASSWORD;
--EXECUTE IMMEDIATE v_STATEMENT1;
P_MSG := 'Password Changed Sucessfully';
END IF;
END;
EXCEPTION
WHEN E_PASSWORD THEN
P_MSG := 'Missing or Invalid Password';
WHEN E_INVALIDUSER THEN
P_MSG := 'User '||P_USER_id||' Does not exist';
END;
I have created a synonym with the same name as sp_alteruser and given the execute privilege to the user vijay...
This procedure works fine when I run as DBO user, when I am trying from the vijay user it is throwing the error as insufficient privilege.
I tried to give the alter user privilege explicitly but none gone right, when i gave dba privilege and checked with it works fine..
Please help me in this regard.
Thanks
vijay

Yes, I got it and apologies. Its not there so the error is correct. I am not sure that which priv is letting the dba role change another user, here is a list of privs for some default roles but none of them is there which depicts clearly the option to change another user.
A very stupid answer, try giving the alter user with the admin option and see what happens. I don't ahve a db here otherwise I would had done it.
