Splunk and Shibboleth

[Grinnell, Michael (mg7aa)]

Does anyone have a good Splunk field extraction regex for Shibboleth 4 logs?  The "official" Shibboleth add-on appears to no longer be supported by Splunk.  I found these when looking around, but they are really old and incomplete, at least for our logs.
