We're using MediaWiki 1.19 (latest version) and we've integrated CAS
to enable Single Sign On over our systems.
There are 2 problems here:
If we use Chrome browser, we can successfully use Single Sign On feature.
if we use Firefox, Internet Explorer, If we're logged in in mediawiki
(using CAS), we still have to log in again on other service (NOT SINGLE
SIGN ON), but if firstly we logged in on other services, then mediawiki
automatically single sign on.
I don't know if it's whether error from mediawiki or browser ?
Thank you for reading.
