Sync fails with 389-ds LDAP server

[tjmcomp]

When trying to sync contacts i get the following error on the LDAP server
SRCH base="ou=contacts,dc=example,dc=com" scope=2 filter="(objectClass=*)", invalid attribute request

The app reports Protocol error as the reason for the sync failure

The same result is experienced on various devices.

I have traced the error to L162 in LDAPUtilities.java
String[] ldapArray = new String[preferences.getAll().size()];

The size produces to null value elements in the array which are the baseDn and filterString keys which are excluded. This produces an attribute string for the request which has 2 invalid attributeNames as null.

This can be fixed with String[] ldapArray = new String[preferences.getAll().size() - 2];
