.ldap.search now takes 4 parameters

1. sess the integer representing a session created with .ldap.init
2. scope the integer representing the scope of how a search should take place
3. filter the string representing how to filter the search process
4. customDict a dictionary where a user can overwrite the default operation of the 'old' parameters
