These entries make me think you could probably speed things up a bit 
with a tighter search scope.  It looks like you're searching the whole 
DIT every time since you've got your machine and user accounts split 
up.  I'm assuming you also have nss configured to search dc=XX 
Company,dc=pl?sub.  I'd suggest either merging the user and machine OUs 
or perhaps putting both of them in a container OU you can search in, 
rather than doing the whole LDAP tree.  True, that won't solve the 
multiple searches problem, but it should help along the speed of the 
searches that it does do.
