[horde] H5: ext. Calendar fails with SSL certificate verification error

[Jan Schneider]

Zitat von Stephan Kleber <stephan at admin.nabira.de>:

> Hi all,

> using Horde 5.0.4 (with kronolith 4.0.4) I have an issue with SSL
> certificate verification. I couldn't find a solution regarding the error
> message: "fopen(): Failed to enable crypto".
>
> But first the details:
>
> When I try to add (subscribe) an external calendar to kronolith I
> receive the error to be seen in attachment HordeNewCal.txt
>
> Of course I checked whether the openSSL verification itself works (see
> HordeCmd.txt) using the horde commandline to make sure it is no file
> system permissions problem for the web server to access the certs or
> similar. The CA cert store path is correctly for my system set to
> /etc/ssl/certs/ (openSSL works fine with that directory as seen above).
>
> The "fopen(): Failed to enable crypto" lead me to (not) horde-bug #11822
> and php bug https://bugs.php.net/bug.php?id=52106 and similar things.
> But using PHP 5.3.3-7+squeeze14 at least I did not find anything
> directly applicable.
>
> Any ideas?
>
> If not: Which php-mechanism is used to verify the cert? Is it something
> I could try out separately to confirm or disprove a PHP or PEAR library
> problem?
>
> Anything else I could do or try?
>
> Thanks,
> Stephan

Try to install the curl or http php extension.
