Hello all,

I have analyzed this problem again. What happens is that a given users
level of access is imposed on any subsequent user of the SAME system
when accessing Dspace under one of the following conditions 
1) Once login is attempted within 2-4 mins of the first user's logging
out. 
2) The subsequent user logs on while the first user is logged into
dspace from another location. 

For example if User "A" accesses "sys 1" then logs out and User "B"
attempts to access the same item on "sys 1" within 2-4 mins then "B" is
given user "A"'s level of access whether that means complete access or
being denied entry and the logged in user will APPEAR TO BE USER "A".
Also if User "A" now logs in on another system say.. "sys 2" then any
user who access ANY system that "A" has used, will then have "A"'s level
of access imposed on them and see themselves logged in as "A" while "A"
is logged in and has accessed the item in question.... I have tested
this many times.... 

Has anyone observed this or solved this issue??

Thanks for any info..

Nigel

In my experience I don't think this can happen - even if I'm looking at
a cached version of a page that seems to suggest I'm logged on when I'm
not, as soon as I click to try and access protected content, the
authentication/authorisation bits of DSpace kick in and start looking
for a valid authentication context - as this context isn't actually
there (despite what the cached version of the page is telling me), I
can't get access to the protected content . . .

> and see themselves logged in as a privileged user...

Again, I don't *think* this can happen - as Christophe pointed out, it's
not DSpace that is serving a cached version of the page, but the browser
"reusing" a locally cached version - so a user will only see themselves
logged on if they (or someone else) has previously logged on to the
system, and then logged off again, in the same browser session . . .

I've certainly not heard of anything like the scenarios you describe
actually happening - the problems I hear about are usually the "other
way around" - I've had numerous enquiries from our workflow staff
relating to things like the "Edit" button not being visible on an item
view page - these are always problems relating to a cached version of
the item view page - they access an item page, then subsequently log on
and go back to that page, but don't get access to the admin features
(the give away is always the absence of the "Logged in as" message).

Hope that helps.

Mike
