If you start winbindd on these systems, you might mitigate part of the
problem, short-term. (The bug is real, and in solaris a per jra's
comments). Winbind will handle the connection to the DC, rather than
each smbd. It's much faster this way too.
You don't need to be using winbindd in nsswitch or PAM to take advantage
