[JENKINS-50016] Contents of saml-sp-metadata.xml changes whenever jenkins service is restarted locking users out

Description

Original: Jenkins setup was configured to talk to AD via SAML,  Users could login via SAML and Jenkins could show AD groups associated with users. All working as expected. A plugin update was available which required Jenkins to be restarted. Upon initiating the plugin update and requesting Jekins to restart resulted in users being locked out with an OOPS message. Restarting Jenkins service either via the WebUI or manually from the backend (systemctl restart) appears to re-generate the contents (x509Certificate data) in JENKINS_HOME/saml-sp-metadata.xml . Thus user is locked out with the following OOPs being reported; {code:java} org.pac4j.saml.exceptions.SAMLException: Authentication response is not success ; actual urn:oasis:names:tc:SAML:2.0:status:Responder{code} Not sure if regenerating the contents of saml-sp-metadata.xml is expected behaviour by design for perhaps security reasons?   Possible Workarounds; # Send new JENKINS_HOME/saml-sp-metadata.xml  file to IT team to import into AD server - need to confirm this works. # Attempt to restore a backup copy of JENKINS_HOME/saml-sp-metadata.xml  - attempted but this didn't work.

The autogenerated key store is created in each restart, so the key change, there is a development in progress to change this behavior, you can configure the encryption settings with a custom keystore that you have to create this one will not change on every reboot.
