ISIS-2157 fixes auto-create user related vulnerability
When using delegated authentication, desired behavior is to auto-create
user accounts in the DB only if these do successfully authenticate with
the delegated authentication mechanism, while the newly created user
will be disabled by default.
> Secman: Non-existing User gets created in DB even though not authenticated
> via LDAP

>
> When using Secman with delegated authentication to LDAP, any login attempt
> authenticated or not will create an (disabled) user-account in the DB.
> While not a security risk, this allows attackers to 'fill' the database with
> arbitrary garbage.
> Desired behavior for this scenario is to auto-create user accounts in the DB
> only if these do successfully authenticate with the delegated authentication
> mechanism.
