Hi Abhishek, The LDAP org involves many database tables so even going some custom path of modifying the DB directly to change arcotDB organization to an LDAP will be a tedious path and may ultimately lead to DB corruption.
As per your last comment you had to create another arcotDB based organization to test a ruleset. You can later delete it and to completely remove it you will need to remove it directly from DB tables.
thanks
