Problem of SAP* user in New Client

Dear All,

My platform is

O/S : Windows 2003

SAP Ver. : ECC 6

Database : Oracle 10g

After installation of sap I have created new client say 300. After creating for client copy I tried

to login in client 300 using SAP* user and password PASS, it gives invalid password message.

I have search on internet and in some forum it is suggested that set the parameter

"login/no_automatic_user_sapstar" to 0 in instance profile and restart the SAP and recreate client.

I have set the same, restart SAP and recreate client but the problem remains same.

I have also tried with "login/no_automatic_user_sapstar" by value 1.

I request you all to please give me reason and solotion for the same.

Thanks in advance
