Hello All,
after updating Carbonio CE 23.3.0 to 23.4.0 SPNEGO stopped working. On page /service/spnego/snoop.jsp and /service/spnego/ show
HTTP ERROR 403 system failure: not supported
URI: /service/spnego/ STATUS: 403 MESSAGE: system failure: not supported SERVLET: SpnegoAuthServlet
in /opt/zextras/log/mailbox.log

I've just installed CE 23.9.0 and got the same issue.
I've managed to configure all other services to use kerberos ( direct imap 7143, proxy imap 143, smtp 587) but only can't run it on web client.
How to enable debug of spnego?
Keys from here https://github.com/zextras/carbonio-mailbox/blob/main/store/docs/spnego.txt#L454-L461 do not improve logs.
