Hello Everyone, Good evening! Here a Background: I am moving from samba47 to samba48 - I am keeping my existing scripts and config files. The messages below are now appearing while executing some tasks in samba48 only - samba47 is not showing it: #Unknown parameter encountered: "use spnego" #Ignoring unknown parameter "use spnego" #Unknown parameter encountered: "use spnego" #Ignoring unknown parameter "use spnego" Question: is the "use spnego" deprecated for samba48? If so, what is replacing it? Here my smb4.conf file: ######...

I've checked the samba code (sessetup) and found out that samba always send spnego packet when Extended Security capability is ON. (This can't be turned off/on ie. "use spnego = false") Does it mean I can "never" connect to smb server that doesn't support spnego if Extended Security is supported by server? Is my understanding correct? _______...

...this up while trying to figure out why thunderbird on Windows w/ SSPI was not working, but it turned out thunderbird does not use it, so I haven't been able to test it yet. I'm presenting it for discussion only, unless someone else can try it :) Modern versions of MIT kerberos support GSS-SPNEGO natively, but are only willing to negotiate for kerberos tickets and not NTLM messages. This is how the SPNEGO works in libapache-mod-auth-kerb-5.3 which simply passes SPNEGO packets directly to gssapi if the library is new enough. There is even a configure feature test for the gssapi library in...
