[Owncloud] Heavy LDAP user search

I have configured many software products with ldap access at work. None 
of it scans the whole directory. The problem is, that oc won't recognize 
changes in the directory. When I add a new ldap user or when I change 
the group membership of a user, I expect that the software immediately 
recognizes the changes. It's not very user friendly if I have to wait 
for the next complete rescan of the directory to discover the changes.
