Morning, I am trying out the new version 0.9.4 for both gms and front but I keep getting errors. (Note that I am using the same configuration that I used for previous versions and it worked fine). The gms error appear while trying to start such service, but as it can't log with Kafka, it keeps failing. The front error apppear while trying to log in with an OIDC user.

The frontend error is separate and should be at least partially fixed in HEAD, there was a PR that went out last night related to it and it is a known issue reported by several users now with OIDC. The GMS error seems to be that it's not finding your Kerberos keytab: Krb5LoginModule.attemptAuthentication

if (ktab == null) {
                    promptForPass(getPasswdFromSharedState);
                    builder = new KrbAsReqBuilder(principal, password);
                    if (isInitiator) {
                        // XXX Even if isInitiator=false, it might be
                        // better to do an AS-REQ so that keys can be
                        // updated with PA info
                        cred = builder.action().getCreds();
                    }
                    if (storeKey) {
                        encKeys = builder.getKeys(isInitiator);
                        // When encKeys is empty, the login actually fails.
                        // For compatibility, exception is thrown in commit().
                    }
                }

Can you check if your keytab is being properly mounted in the expected location?
