Hello.

I mounted a driver by administrator's right - elevated right with DOKAN_OPTION_CURRENT_SESSION option via mirror sample.

But the drive cannot be accessed and be shown by a normal user.

How can I solve this issue?

Hi @bluenred9 ,

This is the expected. The admin user is running in a different session that your explorer that is running in your user session. What are you trying to achieve exactly ?

[bluenred9]

Thank you for reply.

But a sessionId of a normal user is same with a sessionId of a user who has administrator's right(evelvated).

Your statement is incorrect. You can use your task manager and see your admin command prompt is run as Administrator user and not your normal user. It is two different sessions.

@Liryna

As you can see below, a session id of a evelvated user is 1. A session id of a normal user is 1. They are indentical.

My bad I gave incorrect guidance. The reason is by design. The mount point is created with IoCreateSymbolicLink in the session/context of the user call. This symbolic link is only accessible in the context that it was created. For me this is by design (Microsoft) and probably what people want to achieve when using this option.

If someone wants to limit the access to the user and the elevated process, it can provide an adapted security descriptor for the mount or simply mount as a folder in the user directory.

@Liryna Then... If so, how do I make it accessible to a windows account(both evelvated and normal) without global mount?

[Liryna]

You can mount in a folder and use subst command to assign a letter for example.
