Hi there- We have two media-wiki (1.3.9) based wikis installed on a single server. The problem we're facing is that when we log into one of the wikis, and then go to the other (e.g. two windows/tabs in firefox), then try to edit in the first, it *always* forces us to re-login. This *really* sucks :-(. Everything else is working really, really well. Some details: the server is running linux/apache2, both wikis have alias directives in the apache config to do 'index.php' url hiding. One wiki is limited access, controlled by the apache mod_auth_ldap via apache access restriction directives. (Note, we're not using Apache's own mod_auth_ldap, but an alternate one that supports nested groups.) Both are on running from the same domain, just different directories/sub-URLs (e.g. http://foo.bar/wikiA & http://foo.bar/wikiB .) I've done some googling/read the release notes, and can't find any pointers, other than some notes in earlier version release notes that imply this problem shouldn't be happening. Any help greatly appreciated, I'm relatively new to setting up apache/php/media-wiki. (PS- unless there's a known bug, I don't want to upgrade media-wiki just to see if that fixes it... unfortunately I don't have a lot of time to support these sites, and need to 'save' time for an expected upcoming hardware upgrade, which is when I hope to update the software.) Thanks in advance- Julian
