Not in 4.5, but will in 5. It requires PHP 5.4 (or a patched 5.3 with the 
functions ldap_control_paged_result and ldap_control_paged_result_response)

Change the cache TTL in Settings → Admin → LDAP Advanced.
In future (probably >=4.5.2), the cache will be cleared on every Save in the 
settings.

What you have probably seen were arguments like $offset and $limit which can be 
passed when for example users or groups are retrieved, but not all of them at 
once (e.g. for pagination). 
→ ownCloud is able to handle larger LDAP envs.
