Hello,

We got the following error when try to config SAML on our Mahara instance.

AH01071: Got error 'PHP message: [WAR] d2 (lib/errors.php:530) [SimpleSAML\\Error\\CriticalConfigurationError]: The configuration is invalid: predis/predis is not available. at /var/www/html/auth/saml/extlib/simplesamlphp/lib/SimpleSAML/Store/Redis.php:31PHP message: Call stack (most recent first):PHP message:   * exception() at Unknown:0PHP message: PHP message: PHP Fatal error:  Uncaught Error: Call to undefined function xmlrpc_error() in /var/www/html/lib/errors.php:662\nStack trace:\n#0 /var/www/html/lib/errors.php(541): MaharaException->handle_exception()\n#1 [internal function]: exception()\n#2 {main}\n  thrown in /var/www/html/lib/errors.php on line 662'

it looks like we don't have predis/predis module.  Does Mahara release package have predis/predis? 

Thank you!

Hi Jin,

The predis vendor module should be included with the release package - what version of Mahara did you install and what was the name of the release file?

The predis vendor module should be located at htdocs/auth/saml/extlib/simplesamlphp/vendor/predis/predis/

If you are installing via git you will need to run

make cleanssphp && make ssphp

from commandline in the same directory as the Mahara's 'Makefile' file

Cheers

Hi Robert,

Thank you for the reply.  We installed Mahara 23.04.04 with PHP 8.1 and the file we download was mahara-23.04.4.zip (with PHP 8.1).  I downloaded the file again today and unfortunately I couldn't find the predis module in the package. 

I also downloaded the release package with PHP 7.4 and the PHP 7.4 package has the predis module and a lot more vendor modules than the PHP 8.1 package.     

Thanks.

Hello,

is that possible to provide a new PHP 8.1 package with these vendor modules?

Thanks!

Hi Jin,

We are in the process of getting this fixed up and should have updated release files for PHP 8.1 later today

Cheers

Hi Jin,

This is taking longer than I first thought - hopefully I should have this fixed up by the end of next week

Sorry for the delay

Cheers

Hi Jin,

I've added compiled release files for Mhaara23.04.4 PHP 8.1 with Redis working with SAML to https://git.mahara.org/catalyst/mahara/-/releases/23.04.4_RELEASE

Please try one out and let me know if it works for your situation

Cheers

Thanks.

Hello Robert,

I hit another road blocker after installed the new files. I still cannot view the SAML metadata page. Here is the error log when I try to view saml metadata page.  Also, another related question, do you have instructions for compiling code from source?  

AH01071: Got error 'PHP message: [WAR] ff (lib/errors.php:530) [Error]: Call to protected method Gettext\\Translator::addTranslations() from scope SimpleSAML\\Locale\\Localization at /var/www/html/auth/saml/extlib/simplesamlphp/src/SimpleSAML/Locale/Localization.php:239PHP message: Call stack (most recent first):PHP message:   * exception() at Unknown:0PHP message: PHP message: PHP Fatal error:  Uncaught Error: Call to undefined function xmlrpc_error() in /var/www/html/lib/errors.php:662\nStack trace:\n#0 /var/www/html/lib/errors.php(541): MaharaException->handle_exception()\n#1 [internal function]: exception()\n#2 {main}\n  thrown in /var/www/html/lib/errors.php on line 662'

Hi Jin,

Did you extract the files from the zip over existing files? There might be files within auth/saml/extlib/simplesamlphp/ that are not meant to be there anymore.

Cheers

Robert
