Yest, that's right. Permissions to write PVs. But logging out & in, or

using 'sudo' are not acceptable solutions for this situation. Any

solution has to come from the Phoebus graphical interface. No command

line. The computer session has to remain untouched.

Best,

Óscar

We are going to have several users using Phoebus. Different users have
different permissions to view and to edit, like any other system.

the change has to be made without logging out from the current computer session.

Permissions to do _what_?
Write PVs?
That's handled by Channel Access (or PV Access) security, which is based on the current user.
Phoebus (or EDM, MEDM, python CA library, command line caput, ...) don't have any way to change that user.
The only option you have is either log out & log back in,
or use 'sudo' to change user and start another instance of the program as that different user.
