This is a bit strange. What I do know is that a couple of months ago 
(6-7 months ago?), the password length for admin was changed to at least 
6 letters, to be consistent with the documentation. The documentation 
has always stated that the password length must be at least 6 letters.

Now, I am not sure if it affects the users too. The type of password 
probably shouldn't matter. If it does, then it is a serious problem.

Can you check and reproduce these problems in a new notebook directory? 
This might help in narrowing down whether the problem is in sagenb or in 
the old worksheet directory. To create a new notebook directory, you 
need to run sage as follows:

sage -n directory=/tmp/new.sagenb

The directory /tmp/new.sagenb need not be present. It will be created by 
sage.  By the way, sage-5.2 works with flask notebook. It won't work 
with the old notebook since there are changes to sage itself brought 
about by the transition to flask notebook.
