SAP NW Solution Manager 4.0 Administrator/J2EE_ADMIN password locked out

Guys,

I was successfully able to install SPA Solution Manager v4.0(ECC 6.0) JAVA+ABAP Stack.

Post Installation, I am tried to logon to the SolMan (User Management & SAP Netweaver Adminsitrator) through HTTP (IE) URL http://<localhost>:port

The homepage displays just fine. When try to authenticate to User Management & SAP Netweaver Adminsitrator using following commbinatioln, the authentication fails.

user = J2EE_ADMIN password = <ADMIN>

OR

user = user = J2EE_ADMIN password = <admin> (Not sure if the password is case sensitive)

Now, I looked at the alerts and found that J2EE_ADMIN user is locked.

Does anyone of you know how to unlock this id and what its password should be ?

Any alternative user id/password can be used to login ?

Should I have to install SAP GUI for Java or ABAP ?

Please help me login to solution manager.

Thanks for your help!!

Chris.
