Security settings on LDAP connector

Only what is mentioned in IDP-1196 which is basically to do what we did to the MetadataResolver in V3 (inline the 99% case either
with a <Certificate> or with a "trustFile=foo.pem" and use bean references for the rest.

Sounds essential - so if 1196 looks wrong please scream.
