- From Kepler-Patch-25 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
NG Mobile
- Changes are not synced to Android devices if attendees of an instance in a recurring appointment are modified. - ZBUG-3133.
