No (IMHO). The sample /etc/nsswitch.conf shipped with libnss-ldap has it
look for everything in LDAP. I have mine setup to use LDAP for passwd and
group only. I have attached my /etc/nsswitch.conf file to this message.
Also Brian I just checked your machine and it seems that you are using quite
a bit of swap space. Maybe if you had more RAM then the database files for
LDAP would stay in cache and the libnss shared objects would also stay in
cache giving considerably better performance.
I would suggest increasing your RAM by 50% at least.
