I set up an environment to reproduce your issue: - DokuWiki Anteater with Git version 2011-02-08 - "addnewpage" installed - Debian 5.0.7 with Apache 2.2.9 - krb5-user 1.6 - Authentification against Windows 2008 Datacenter with ActiveDirectory and DNS role. - 50 empty directories inside data/pages - Page browsed with http://192.168.0.101/dokuwiki/doku.php?purge=1 AD-Authentification with {{NEWPAGE}} in startpage: Page loaded in: 2,91 sec execution of auth.php: 43ms http://wiki.lupo49.de/~lupo49/tmp/dokuwiki/xdebug_AD_AUTH.png http://wiki.lupo49.de/~lupo49/tmp/dokuwiki/xdebug_AD_AUTH_Overall.png Plain-Authentification with {{NEWPAGE}} in startpage: Page loaded in: 2,69 sec Execution of auth.php: 4,7 ms http://wiki.lupo49.de/~lupo49/tmp/dokuwiki/xdebug_PLAIN_AUTH.png http://wiki.lupo49.de/~lupo49/tmp/dokuwiki/xdebug_PLAIN_AUTH_Overall.png Maybe my environment is missing a needed detail, but for it is working kinda smoothly. Normally the systems would be a little more faster, if they aren't running in a virtualbox and connected by wirelss lan to each other. If it's worth for you, you could enable xdebugging and take a deeper look inside the php function calls, to get the execution time of each. And please make sure that your DNS settings (especially FQDN to ActiveDirectory host) are correct. Regards Matthias -- DokuWiki mailing list - more info at http://www.dokuwiki.org/mailinglist
