Oracle error ORA-65052: statement involves operations with different container scope

I'm a relative newb to Oracle. I have set up an instance of Oracle 12c running on a RHEL 7 VM. I am connecting to the database created during installation through and running some installation scripts.

Below is the output from the script that I am trying to run, can anyone point me in the right direction? I have a feeling I'm doing something fundamentally wrong.

Error starting at line : 4 in command -
GRANT CONNECT TO TDSUSER IDENTIFIED BY "TDSPASSWORD"

I think this Q & A on the Tridion beta Stack Exchange site may help you:

Oracle Content Delivery CreateTridionSYSUser.sql errors

Basically you need to be in the pluggable database because of the multi-tenancy that is a new feature of 12c.

alter session set container=pdborcl;
