Subject: Can't login since Actice Directory password change
Hi all,

We've been running Dokuwiki nice and smooth for well over 12 months now, even through various upgrades.

Yesterday we had to change our Active Directory/Domain policy to reset some users' passwords. The users have logged onto their respective computers etc after changing their password and all is well, except that when we attempt to log into Dokuwiki using our new AD passwords, we just hit a blank web page (after clicking ('login'), with something similar to the following in the address bar:
"http://dokuwiki.hayley-group.local/doku.php?id=start&d…".

I have tried restarting apache and even upgrading to the new "Binky" version of Dokuwiki but it doesn't fix it. I have also tried Chrome and Firefox browsers.

Any advice would be appreciated.

Thanks.

Elliot

P.S. We're running Dokuwiki on CentOS 6.4. And we're obviously using AD authentication for Dokuwiki!

I have just found this in the HTTPD error_log, but I don't know where to start fixing it, considering all I'm aware that's happened is that users have changed their AD passwords.

Okay, some further googling seemed to point to php-bcmath being needed? No idea how Dokuwiki has been performing awesomely until now if it's so important.

Anyway, I have installed the php-bcmath package, which in turn updated other components such as core PHP. A bit worried about this as we run some old projects on this server and the upgrade has probably upset some of them.

But, the good news is that Dokuwiki is now working again!

Hi HayleyIT,

thank you for record this behaviour. We're running Dokuwiki on CentOS 6.4 too and have the same problems and the same entries in our error_log. After installing the php-bcmath package everything is ok.

Greetings
