IMAP authentication changes

[Robert Sparks <rjsparks@xxxxxxxxxxx>]

All -

We have changed the way the IETF IMAP service authenticates against the 
datatracker.

In the process, we also discovered a bug that was allowing some people 
to authenticate with bad passwords that has been corrected.

If you can't authenticate with the IMAP service now, but you have been 
able to in the past, please check that you are using the password that 
goes with the username you have provided. Note that the IMAP service 
does not (yet) let you login with any email address known to your Person 
the way the datatracker does. Your password will need to match your 
actual datatracker User username. This is something that we're working 
with Alexey to change in the future so that it behaves exactly as the 
datatracker does.

If you try the above and are still not able to access IMAP, send email 
to support@xxxxxxxx.
