Table ldapauth Primary Key

Although not certified by drupal.org have been working with Drupal in a MySQL Cluster, version mysql-cluster-gpl-7.0.7-linux-i686-glibc23, in a test environment. Found that table ldapauth created by module ldap_integration, once converted to the MySQL cluster engine, NDBCLUSTER, can not be dropped, reverted back to MyISAM or manipulated in any way. Found the problem to be the definition of the primary key and index. By default the field "sid" is auto_increment but has a non-unique index. Field "name" is the primary key. By redefining the auto-incrementing field "sid" as the primary key (as it should be) and placing a unique index on field "name" the table behaves as it should in the MySQL Cluster environment.
