Progress report.
After succesfully logging into my own notebook as admin, I started to
set up a few user accounts. I followed the instructions in the
notebook? docstring:
accounts -- (default: False) if True, any visitor to
the
website will be able to create a new
account. If
False, only the admin can create accounts
(currently, this can only be done by
running with
accounts=True for a few minutes, or on
the command
line with, e.g.,
nb = load('./sage/sage_notebook/
nb.sobj')
nb.set_accounts(True)
nb.add_user("username", "password",
"em...@place", "user")
nb.save()
[Note that the path to sage_notebook/nb.sobj may be different than
given above.]
Specifically I did
nb = load('nb.sobj')
nb.set_accounts(True)
nb.add_user("john", "xxxxxx", "[email protected]", "user")
nb.save()
and then restarted the notebook(). Now I could not login as john, nor
as admin. Reloading the nb,sobj and doing nb.usernames() showed only
'admin', so the extra username was not saved. And admin logins do not
work now either. (I just get a whilte screen with nothing in it at all
after pressing the "sign in" button, while the tab shows "Error |
Sage ...]
Am I doing something stupid?
