[Mediawiki-l] plexcel SSO and/or mediawiki issue

[Sam Ami]

hi all

i'm having an issue with plexcel or mediawiki, not sure which of the two.

i've successfully setup plexcel to perform sso and all is working
well, no issues at all, all our domain users can sso perfectly

the only issue i've found is with the below groupMap statement i've
added to LocalSettings.php

$wgAuth->groupMap = array(
     'OURDOMAIN\\wiki-admin' => 'sysop',
);

regardless of weather on not i place myself in the
"OURDOMAIN\\wiki-admin" i still do not get sysop status on the wiki.

is there any way i can check this or force mediawiki to do a gpupdate
equivalent ?
