User without the global create credentials permission can't create credentials for a project for which they do have the create credentials permissions. 

Configuration

• Role1 has global create, delete, manage domains, update and view credentials permissions
• Role2 has project create, delete, update and view credentials permissions
• Role2 has global view credentials permission

Issue

Users with only Role2 can't create credentials for the job. 
The add button is greyed out and the add credentials options doesn't show in the side menu.

Users who also have **Role1 can create global and job credentials.
Users with only Role2 should be able to manage credentials for the job without the need of the global permission.
