1. To create users in ODI, go to the security tab, click the add icon, provide a username and password along with expiration dates, and save.
2. New users initially have no access or profiles assigned. Profiles like CONNECT, DESIGNER, METADATA ADMIN, OPERATOR, and TOPOLOGY ADMIN must be granted from the master repository to allow access to different areas of ODI.
3. Once all necessary profiles are granted, the new user will have full access to create, view, edit and manage objects in various areas of the ODI repository like designer, metadata, operators, and connections.
