      Versions
      Ubuntu 18.04.3 LTS
      Apache 2.4.29
      Kopano 8.7.85
      WebApp 3.5.13.2537+1469.1

      Bug Description
      Since updating to Kopano 8.7.85 Kerberos SSO isn’t working anymore. Logging in with Kerberos SSO for example with SSH is working well. The WebApp just keeps loading:

      c90d74e6-533f-4d68-9a07-a93a478b80a9-image.png

      PHP Fatal error:  kc_session_restore(): kc_session_restore() expects parameter 1 to be string, but something else was given in /usr/share/kopano-webapp/server/includes/core/class.webappauthentication.php on line 216, referer: https://my.url.com/

      Severity
      Major

      Steps to Reproduce
      Just follow the manual --> https://documentation.kopano.io/kopanocore_administrator_manual/special_kc_configurations.html#sso-with-kerberos

      Actual Behavior
      Logging in to WebApp with Kerberos isn’t possible.

      Expected Behavior
      Logging in to WebApp with Kerberos is possible.

      Troubleshooting/Testing Steps Attempted
      I verified the Kerberos authentication on the server itself and this is working well.

      Workaround
      No workaround found yet.

        I just found a workaround:

        I copied the file “class.webappauthentication.php” from WebApp version 3.5.12.2499+1440.1 over the actual one and authentication is working again.

        Regards
        Richard

              You should update to 3.5.14.

                I just updated to version 3.5.14.2540+1473.1 and the problem seems to be gone now.

                Thank you!
