Removing/fixing shibboleth stats in Apache logs

[Roland Tanner]

Hi,

I use Awstats for analysing server stats, but I've found that users 
logged in with Shibboleth can cause Apache logs that 'break' Awstats.

Here's my general log entry:

domain.org 92.21.59.46 - - [17/Sep/2012:20:30:47 -0400] "HEAD / 
HTTP/1.1" 200 - "http://www.referrer.com" "Mozilla/5.0 (Windows; U; 
Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3"

And here's a shibboleth log

domain.com 82.34.228.251 - 
https://idp.university.ac.uk/shibboleth!https://some.resource.com/shibboleth-sp!p610nflqaikrki6sodm43hb36 
[17/Sep/2012:17:21:13 -0400] "GET /shibboleth/path/to/file.html 
HTTP/1.1" 206 6656 "-" "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 
6.1; WOW64; Trident/5.0)"

The 
"https://idp.university.ac.uk/shibboleth!https://some.resource.com/shibboleth-sp!p610nflqaikrki6sodm43hb36" 
is the 'login name', but Awstats is expecting something that looks a bit 
more like "John", and I presume a character is causing the code to stop.

Is there a quick way to stop shibd adding logs to Apache's logs, or is 
that something that needs to be handled through the Apache config?

Many thanks,

RT
