Using Apache mod_shib22 with IfModule

[Russell Sim]

Hi,

Thanks for the great work on mod_shib, I did try to enter this as a bug
in the tracker but I couldn't find a way to create a ticket without
logging in.

Anyway, I recently needed to add an IfModule section to an Apache config
that would switch on location protection if the mod_shib22 module is
present.  I did some digging in the Apache documentation and your code
and the only way to I could get it to work is:

<IfModule mod_apache.cpp>  # if mod_shib22
    <Location />
	    SetHandler None
	    AuthType shibboleth
	    ShibRequireSession On
	    ShibUseHeaders On
	    require valid-user
    </Location>
</IfModule>

Seems that according to the Apache doc "If a module consists of several
source files, use the name of the file containing the string
STANDARD20_MODULE_STUFF.".  In the case of the mod_shib that is
mod_apache.cpp so the config ends up being a bit odd and kinda
miss-leading.

Cheers,
Russell
