This implements the basic LDAP to WKD mirroring.  The blacklist
option and domain restrictions are not yet fully implemented.

Take care: In OpenLDAP you may need to increase the paged result limit
by using a configuration like:

  dn: olcDatabase={1}mdb,cn=config
  changetype: modify
  replace: olcLimits
  olcLimits: dn.subtree="dc=example,dc=org" size.prtotal=unlimited
