Changes to the CDS login system

Institutional login and changes to the CDS login system

Institutional login (UK Federation via Shibboleth) provides access to 
many databases and restricted web sites using a single id and password,
managed by the home institute to which the user is affiliated. 

This should result in greater convenience and improved security. 
Many University users already have a suitable id for access to e.g.
Web of Knowledge, MIMAS, JISCmail etc.

We have initially introduced support for Institutional login for two 
of the CDS databases - "Available Chemicals" and "Screening Compounds".

To use these two databases only, it is necessary to login BEFORE 
accessing the usual start links in the "red box" menu item on all CDS
web pages.

http://cds.dl.ac.uk/

Two login links are available as follows :

1) CDS Login 
   Accepts the usual CDS id and password. 

or

2) Institutional Login ('Shibboleth')

   Allows you to navigate to your home university, login there with your 
   UK Federation/Shibboleth id, and if it is the first time logged in,
   further CDS screens will allow you to map your existing CDS to the 
   new Shibboleth one. After this access to the "Available Chemicals" 
   and "Screening Compounds" databases will be unimpeded by further 
   login boxes.

   Visitors who do not have a CDS id when first logged in, will be 
   redirected to the Express registration page. The login then needs to
   be repeated with the new id / password.

   When a new web browser session is started, the login must be repeated, 
   and it needs to be done at the start of each day.

For now, access to the other databases is unchanged i.e. a "CDS" login 
popup box appears when the database start link is selected (unless the 
id and password have been saved in the web browser). 

From April 20th, the new "login first" scheme will be extended to all 
of the CDS databases. To help prepare for this, please try to run 
"Available Chemicals" and "Screening Compounds" with your normal 
id/password or using an Institutional login if you have one.

NB Interactive login to CDS e.g. to run Conquest is not affected by 
the new scheme, and will operate with the CDS id/password over ssh 
as before.
