      Description

      I'm loading schema with code like:

      con.loadSchema(new JarLdifSchemaLoader());
      con.addSchema("custom.schema");

      Later an exception is thrown while I'm handling some search results. The entry in question looks like:

      dn: cn=ICRCSSTAccess,ou=Roles,o=jaas,dc=xoint,dc=net
      objectClass: groupOfNames
      cn: ICRCSSTAccess
      member: uid=gturner,ou=people,dc=xoint,dc=net
      member: uuid=98bb35ee-9ff3-444f-9925-7fe762810d50,o=Asus,ou=customers,dc=xoint,dc=net

      The code where the exception is thrown looks like:

      Attribute memberAttribute = entry.get("member");
      if (memberAttribute != null)
      for (Iterator<Value<?>> iterator = memberAttribute.iterator();
      iterator.hasNext()

      { @SuppressWarnings("unchecked") Value<String> value = (Value<String>) iterator.next(); String member = value.getValue(); Dn memberDn = new Dn(context.getSchemaManager(), member); members.add(memberDn); }

      It is the Dn instantiation that throws the following stacktrace:

      OID 1.3.6.1.4.1.38541.2.1.3 is the uuid attribute that is part of a member DN. "custom.schema" defines it as follows:

      attributetype ( 1.3.6.1.4.1.38541.2.1.3
      NAME 'uuid'
      DESC 'The customer UUID'
      EQUALITY UUIDMatch
      SYNTAX 1.3.6.1.1.16.1
      SINGLE-VALUE )

      While scrutinizing the source, looking for why this attribute wouldn't be found in the DefaultSchemaObjectRegistry#byName Map for the AttributeTypeRegistry, I'm beginning to suspect that somewhere around where LdapNetworkConnection#addSchema is calling AttributeTypeRegistry#addMappingFor, it hasn't quite finished the job, perhaps something like calling AttributeTypeRegistry#register (which seems to be the only method that put's into the byName Map).
