[gentoo-science] [sage-on-gentoo] Sage 5.2's Notebook does not accept some passwords

Hello!
  I upgraded Sage to 5.2 today and I have noticed some strange
behaviour with passwords.
  First of all, I noticed that new Sage Notebook did not accept my old
password (which consisted of 3 letters). I started it with
'require_login=False" and reset the password for my regular user. After
that I had an ability to login with the generated password and change
it. However, after changing it to some 3-letters password I cannot
login. I tried the passwords gradually "123456", "12345", "1234" and
"123". All of them worked fine except for the last one. So, "1234"
worked fine, but another 4-letter password did not.
  And what is the most strange is that any password is accepted by the
Notebook server at the time of changing it, but not every password is
accepted at login time.

P.S. I read that Sage 5.2 includes the flask Notebook. Does it mean
that in sage-on-gentoo overlay we have the flask Notebook as well?

  Regards,
    Vladimir
