[Mediawiki-l] External Authentication for MediaWiki?

[A Chan]

Hello,

Has anyone tried to use an external authentication
product with MediaWiki?  We have an authentication
product we are using with our existing applications,
and ideally we would like single sign-on (SSO)
capability to include MediaWiki.

Does this seem feasible?  I'm assuming we would need
to make custom changes to our MediaWiki installation.

Thanks for your help,
