The Samba-Bugzilla – Bug 11297
smb encrypt has weird default value "default"
Last modified: 2015-06-26 23:04:29 UTC
man page says: Possible values are auto, mandatory and disabled. The default is "default" though. It should be changed to "auto".
For SMB2, default has a different meaning than auto.
I have updated the manpage for master to describe the
effects of smb encrypt settings for SMB2.
Will open a bug to backport that.
