But no conclusion was out, I think.
So I try-and-error'ed many many times, and finally I found out what is the
** User who are authenticated via NT SAM must be a member of
"Account Operators" group **
In stead of "Account Operators", "Administrator" group is also OK as you think.
Yes, I solve the "NT SAM Authentication" problem.
But is this feature good SPECIFICATION? -- I don't think so.
That's BUG in code, or BUG in SPEC.
How do you think, all?
I hope this bug will be fixed in the next release.
