Subject: [PATCH] Missing LDAP-style case insensitive search in Entries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Not sure if it should be named like this, but I was missing LDAP-style case insensitive search in Entries.

Maybe use mb_strtolower ? Or an LDAP spec strtolower() implementation.. ?

I'm not even sure if I would merge this as is 😅
