Plan user access in Project Server

  • مقالة

Summary: Learn about the user access permission modes available in Project Web App.
Applies to: Project Server Subscription Edition, Project Server 2019, Project Server 2016, Project Server 2013

Project Server offers two security modes for controlling the kind of access that users have to sites and projects:

  • SharePoint permission mode In this mode, a special set of SharePoint security groups are created in sites associated with Project Server. These groups give users varying levels of access to projects and Project Server functionality.

  • Project permission mode In this mode, Project Server provides customizable security groups and other functionality that is distinct from SharePoint groups.

In both security modes, the SharePoint site administrator for the Project Web App site is also a Project Web App administrator.

When you've determined which permission mode you want to use, more information is available:

New Project Web App instances use the SharePoint permission mode by default. If you have more than one instance of Project Web App, each site can use a different permission mode.

Changing Project Web App permission modes

In an on-premises installation of Project Server, the permission mode can be changed for a given instance of Project Web App by using the Set-SPProjectPermissionMode Microsoft PowerShell cmdlet. For more information, see Set-SPProjectPermissionMode.

In Project Online, the mode can be changed in the Microsoft Office 365 portal site. For more information, see Change permission management in Project Online.

Caution

Switching between SharePoint permission mode and Project Server permission mode deletes all security-related settings. If you switch from SharePoint permission mode to classic Project Server permission mode, you have to manually configure your security permissions structure in Project Server. Switching from Project Server permission mode back to SharePoint permission mode deletes your security permissions information from Project Server.
