[Class name] Net_LDAP2_Filter [Description] 
You are free to give LDAP-Filters on your own to the Net_LDAP2->search() method, however this has some drawbacks (including escaping issues). For this reason, you can use the Net_LDAP2_Filter class to easily build and combine your filters. LDAP filters are extensively explained at the chapter LDAP filters.
