Help Android LDAP contact Address Book live lookup, no times sync

I've got an LDAP contact address book, meant to lookup the S/MIME email encryption details of target mail recipients known to my company.

The LDAP is publicly available, as third parties can also use it to search the S/MIME details of specific staff based on their email address.

Because its publicly available to people I dont know, my LDAP supports anonymous lookup, ie no authentication is required.
Obviously I dont want my entire LDAP to be harvested, so as a counter measure, you can only do live lookups for a matching email address, and when searching for wildcard, only 1 email address is returned.

So I can add my LDAP in Android as a contact account. But apparently when looking up an email address from my default mail client, no email address is returned. Most likely because android does a sync and doesnt do a live lookup.
In Outlook for Windows an LDAP lookup for an addressbook works just fine.

My questions:
1) Can anyone knowledgable on the LDAP in Android, confirm that live lookups in an LDAP contact address book are or are indeed not possible?
2) When it is possible to do live lookups, could you kindly tell me how?
3) If a third party app might be required either for the LDAP support, or a specific mail client app, kindly do let me know

As my LDAP is publicly available, send me a PM and I will provide you with the details, should this help you with helping answering my questions. I also wouldnt mind posting it here, but could be considered a commercial advertisement, and thats definately not how I want to come across.
