"*" is a wildcard, not a regular expression.  To use simple wildcards
like this you need:

  use_regexp_matching=0


If you still want to use a regular expression though, the one you need
which would be equivalent to a "*" wildcard is:

  .*

The "." means "match any character" and the "*" in a regular
expression means "match zero or more repetitions of the previous
element.".
