Some problem when integrating moinmoin with mantis

[smilodon]

I am integrating moinmoin with mantis.And have finished a modified "wiki_moinmoin_api.php".
(when click 'wiki' link,it will go to some like "http://myhost/moin/issue/project1/21" "http://myhost/moin/issue/project1/start" "http://myhost/moin/issue/start")
But now I want to do the Single Sign-On part of this integration.
I go to the " http://www.mantisbt.org/wiki/doku.php/m ... le_sign-on " and " http://moinmo.in/HelpOnAuthentication#line-90 "

Because moinmoin is not writen in php,so I dont think I can do the same thing like integration with dokuwiki.And I think may be using moinmoin 's php_session autherntication way.The method is to read the session file to obtain the login username,email and so on.

But I can't find mantis session file in php session folder(I dont know much about php),when I want to write a mantis session handler.So I want to ask how to do this.

I am using Mantis 1.1.1.

Thanks!
