Creating nncentral Group and User

For security reasons, you must create an NNCentral user account named nncentral and an NNCentral group named nncentral on the server to administer Oracle Communications Session Delivery Manager related server operations. You also must specify limited sudo privileges for the nncentral user and nncentral group. After the Oracle Communications Session Delivery Manager installation, all the installed files are owned by the nncentral account. The main Oracle Communications Session Delivery Manager process has to run as a sudo user in order to have access to port 162.
