Embedded LDAP server LdapAuth3: support hashed passwords (sha1, sha-256)

Note that none of the currently supported hash are safe against
brute force attacks.

If ldapFilter property does not contain any occurrence of "${password}",
the user DN found via the filter expression will be authenticated
via a regular LDAP bind operation, using the entered password. In this
case, with embedded LDAP server, but probably also with others, hashed
passwords are supported and make sense.
