If you set up PA as a system-wide instance you need to configure
things differently than when using it per-session. If you run it as
system-wide daemon than you are expected to understand very well what
is happening. I do not recommend to run it as system daemon.
I know that Gentoo sets up PA this way. This is against my
recommendation. The only use case for running PA as system-wide
instance is thin clients, where the users using PA are not local. If
that's the only focus of Gentoo than great. But the last time I looked
this wasn't quite the only focus of Gentoo. ;-)
If you use PA this way then local authentication works by membership
in the group pulse-rt. What you described sounds like authentication
errors. So please make sure that all users who try to access PA are in
Again, if you use PA as system daemon, then it is your own fault if
things don't work as expected. You are expected to know what you do if
you run PA in this mode.
