Outlook uses VLV's, but if the VLV indexes it uses are not actually 
created, you get really bad performance and some "wierd" errors in 
outlook.  Assuming outlook only uses this if the server says it supports 
VLV controls, disabling this in theory would make outlook "work better" 
than with vlv's supported by the server, but no vlv index created.

The other app that uses VLV's that I know of is the Directory server 
java console.  If you disable VLV's it can affect performance there as well.

What is the reason you want to disable VLV's?  If it is because of 
Outlook, it would actually be better overall to create the VLV indexes 
that outlook uses - they are fairly easy to create, and outlook's use of 
vlv indexes is pretty consistent.

FWIW, Outlook uses VLV indexes for it's ldap addressbook functionality, 
but one other bit of tuning you need to do for Outlook is index the 
displayname attribute (even if you have no entries in the server with a 
displayname value, you need to index the attribute to prevent a 
sequential search of entries to realize this).
