samba - Dec 2016 - client max protocol = SMB3 ?

Hi All,
   The man page for smb.conf says that 'client max protocol = default' 
is the same as 'client max protocol = NT1' for the HEAD samba version.

   Is there some reason I should not change that to SMB3?

Thanks!
Chad.

If you mean 'should I supply a patch to change man smb.conf', then
yes ;-)

The default was changed to 'SMB3_11' when 4.3.0 was released.

Because Unix extensions were not specified for SMB2/3, and we don't
know at protocol negotiation time if the client (user) wants to use
unix extensions, we are a bit stuck.  

In particularly, we didn't want to break existing scripts by
unilaterally turning off unix extensions.  It is hoped to implement
unix extensions in the SMB2 and SMB3 protocols and then in Samba
servers.  However, you can imagine that even then we have a chicken and
egg situation.  :-(

Sorry,

but how is that *now* different to current stable releaes?
besides unix extensions only making troubles and should default to off

https://www.samba.org/samba/docs/man/manpages-3/smb.conf.5.html
Default: client max protocol = SMB3

I don't think we rely on Unix Extensions.  I'll switch on SMB3 with 
libsmbclient 4.2 and see how it goes.

Thanks for the info!
