Suggest UX improvements for tabs with access control

Lets say a tab menu like the example below was used.

Each tab have access control. Some users can see all the tabs, some users can only see some of the tabs, but all user will have permission to at least 1 of the tabs.

To complicate matters, each tab is part of a single big process. For example, if the page have multiples tabs, first tab will be used for the first part of a process, second tab will be for the second part and last tab will be for the last stage of a process.

The access control will be used to control who are involved in each tabs.

What is a good user experience for this kind of system when preventing user from accessing those pages/tabs. For example, should those tabs that user cannot access be removed? The problem of removing tabs is that it break up the continuity of the tabs.
