Trac Ticket #346 - Slow ldapmodify operation time for large

quantities of multi-valued attribute values

https://fedorahosted.org/389/ticket/346

Fix Description: When comparing dn syntax attribute values (e.g.,
member in a group) with filter values, filter values are case-
lowered, but the attribute values in an entry are not any more.
This patch lowers the case before the comparison in the syntax
plugin.
