>          Issue Type: Enhancement

> Currently BCrypt mapper for DB realm does not support MCF format passwords (which does not require explicit salt or iterations):
> 17:42:28,328 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 3) WFLYCTL0013: Operation ("add") failed - address: ([
>     ("subsystem" => "elytron"),
>     ("jdbc-realm" => "DatabaseRealm")
> ]) - failure description: "WFLYCTL0155: 'salt-index' may not be null"
> Support should be added to support MCF password so only single column needed in DB.
> Logic:
> if (password && !salt && !iterations)
>    assume MCF format password
> else if (password && salt && iterations)
>   assume BCrypt (b64) password, etc
> else
>   error
