Subject: MDL-17548 MNET: Fix email links for sites with path component in wwwroot
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=078c1134bfb47a4b99c275b00ee781658fb36450;p=moodle.git

MDL-17548 MNET: Fix email links for sites with path component in wwwroot

Where Moodle sites had a path in their wwwroot, the MNET function that
forced remote users to go via their identity provider (to make sure they
were logged in) previously directed the user back to a URL like
contentprovider.com/moodle/moodle/mod/forum/view.php?f=7 where there
should only be one /moodle in the middle of the URL.
