please allow more robust use of ldap filters upon user import!

please allow more robust use of ldap filters upon user import!

i would like to use a standard LDAP query such as the following:

(&(objectClass=user)(!userAccountControl:1.2.840.113556.1.4.803:=2)(mail=*))

but i get errors upon trying to import users with this filter in place.  this would import all users that are not disabled and have an email address; pretty standard in finding all of your active employees.  PLEASE make it to where we can use standard LDAP compliant queries for importing users!

thank you,
