Fixed Issues

Zimbra Collaboration

  • In the previous patch release, after the log4j package was upgraded, it caused an issue with the zmrestoreoffline utility where the execution did not complete. The issue has been fixed. - ZBUG-2998
  • In the previous patch release, the patch version on MTA, LDAP and Proxy nodes were not getting updated. The issue has been fixed. - ZBUG-2985
  • Mails having unclosed comment tags were not displayed when OWASP sanitization was enabled.

The default value is true which will not display mails having an unclosed comment tag. If set to false, the emails with unclosed comment tags will be displayed. - ZBUG-2978
  • In the previous patch release, after JDK was upgraded, the users could not log in through SAML. The issue has been fixed. - ZBUG-2927


NG HSM

  • From Joule-Patch-32 onwards, customers using SSO will need to update zimbraVirtualHostName attribute for the domains. Please refer to the instructions to update the attribute.
  • With JDK 17, weaker Kerberos encryption types like 3DES and RC4 have now been disabled by default. This can cause SPNEGO auth to fail if described encryption types are being used. We recommend using stronger encryption types like AES256.

To get SPNEGO auth working with weak encryption types, weak encryption can be enabled by setting the allow_weak_crypto property to true in the krb5.conf configuration file. Please follow below instructions:

1. In /opt/zimbra/jetty_base/etc/krb5.ini.in -> [libdefaults] section, set allow_weak_crypto = true

2. Restart mailboxd service:

su - zimbra
zmmailboxdctl restart
