Subject: strings in LDAP are case-insensitive (#8)

Thank you @wxiaoguang !

* strings in LDAP are case-insensitive

* optmize routeFunc (faster, case-insensitive)

* small optimiztion to routeFunc

* request the directory server to return operational attributes by adding + (the plus sign) in your ldapsearch command.

* request the directory server to return operational attributes by adding + (the plus sign) in your ldapsearch command.

* request the directory server to return operational attributes by adding + (the plus sign) in your ldapsearch command.

* remove operational attributes
