The libkadm5 functions hdb_open() and close around all HDB ops. This meant the previous implementation of kadm5_lock() and unlock would always result in a core dump. Now we hdb_open() for write in kadm5_lock() and hdb_close() in kadm5_unlock(), with all kadm5_s_*() functions now not opening nor closing the HDB when the server context keep_open flag is set. Also, there's now kadmin(8) lock and unlock commands. These are there primarily as a way to test the kadm5_lock()/unlock() operations, but MIT's kadmin.local also has lock/unlock commands, and these can be useful for scripting (though they require much care).
