I guess that was the upgrade for fixing the “badlock” vulnerability in
Samba, which changed the authentication code quite a lot.
FWIW, I found that such fix made evolution-ews unable to login with
non-ANSI passwords (which used to be possible when using NTLM
authentication), but I didn't investigate it.
Milan, I guess you won't have a basic cli program with an evolution-ews
stub which simply authenticates against Exchange, would you?
