Why no I don't!  And it changes priority.  I swore it didn't work before
when I tried it.  I've just now added "session required
/lib/security/pam_limits.so" to /etc/pam.d/common-session, as others
suggested, maybe that did something?
So does that mean the -P flag can never set priority 70?  I got it from your
site!

Thanks.
