Hi Robert, thank you for your hints! There is no jabberd. Looking at the docs it seems that it is only used for "Traditional Clients". We run salt client only. Meanwhile I found the reason for the error: update-ca-certificates at openSUSE doesn't work as on other Linux-OS. Usually I put the (root-) cert into the directory /etc/ssl/certs/ , run the script and the system's CA bundle gets updated. At openSUSE this script is removing the new root-certificate from this directory without using it. On the other hand, a server certificate that has been saved there doesn't get removed... I found the solution at https://unix.stackexchange.com/questions/80131/how-do-i-install-a-system-wid... : At openSUSE I have to push the new root-CA to /etc/pki/trust/anchors/ and the script is collecting it to build the new ca bundle. After some minutes the two jobs returned to work. To answer my question: It seems that Apache-Tomcat is using the CA bundle of the OS.

Hi,

since some weeks we receive (usually after a reboot of the Uyuni server) "TASCOMATIC NOTICATIONS": Subtask kickstartfile-sync failed. Subtask cobbler-sync failed.

At the log file /var/log/rhn/rhn_taskomatic_daemon.log we see messages like these one:

2023-01-30 18:15:00,201 [DefaultQuartzScheduler_Worker-12] ERROR com.redhat.rhn.manager.kickstart.cobbler.CobblerLoginCommand - XmlRpcFault while logging in. most likely user doesn't have permissions. redstone.xmlrpc.XmlRpcFault: :[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)

[..] Caused by: redstone.xmlrpc.XmlRpcFault: :[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)

Actually we renewed our internal Root-CA certificate last month, added a new certificate chain to /etc/apache2/ssl.crt/ and included it in /etc/apache2/vhosts.d/vhost-ssl.conf . Webbrowsers show the updated certificate chain. Initially we forgot to add the new Root-CA-certificate to /etc/ssl/certs/ (+ run "update-ca-certificates") but this has been fixed meanwhile.

I wonder if /etc/ssl/ca-bundle.pem is used by Apache Tomcat for validation of SSL-server certificates?

Any other idea?
