...an 'Access Denied'. After some debugging, I'm putting this down to the fact that, with the Windows 8 client, the GSS-API SPNGEO KRB5 mechanism is selected, which is what I (and SSSD wants). However, looking at the Windows 10 sequence of events, I see that it attempts to use the NTLMSSP mechtype. I choose winbind over SSSD, and if anything would have expected the behaviour above to be the other way around with Windows 8 maybe using NTLM. Is anyone aware of this issue with Windows 10, or is it possible to disable the advertising of the NTLMSSP mechanism, or force Windows to use KRB5? Th...

> gensec_spnego_client_negTokenInit_step: Could not find a suitable mechtype > in NEG_TOKEN_INIT Turns out that this error comes up when gnutls enforces fips mode. Behaviour of gnutls when fips mode is enabled is different in Centos7 vs Almalinux 9.4. With updated gnutls, samba fails when fips mode is enabled. Workaround is to use the GNUTLS_FORCE_FIPS_MODE environment...

...I used Wireshark to look at the packets, and there is one glaring difference between the working samba install and the non-working samba install: in the Session Setup andX Request packet (under the "security blob") that the client sends to the samba server, the working one lists one mechtype: NTLMSSP. The non-working one lists three mechtypes: MS KRB5, KRB5, NTLMSSP, in that order. The non-working one has a krb5 ticket further down in the packet. Samba logs show an error: Failed to parse NTLMSSP packet, could not extract NTLMSSP command [2009/03/18 10:39:36, 1] libsmb/ntlmssp.c:n...

Hi Louis, thanks for your reply. -<| Quoting L.P.H. van Belle via samba <belle at bazuin.nl>, on Wednesday, 2019-02-13 04:59:55 PM |>- > > DOM.AIN\foobar's password: > ^^^^^^^^ > > No dot is allowed in the NTDOM > Fix that first, then try again. That’s the output when logon succeeds though nor does the value seem to matter anywhere else. This is just Samba
