Access control in TWiki at CERN

This TWiki installation is a managed Wiki, divided into Webs. Some webs are public, allowing anyone on the Internet to view the content. Many other webs are only accessible to CERN users, logged in via the CERN Single Sign on with a CERN account or CERN external account.

There are also webs that have restricted access to a list of users or groups, using the TWiki access controls as documented in TWikiAccessControl. At CERN, we are now using E-groups instead of TWiki groups for authorisation purposes. In order to access protected pages, you may need to be part of a specific e-group.

You cannot access pages you expect to be able to access?

1. First make sure that you are logged on with the right username. You should normally login with your main CERN account or the account that corresponds to the email login for your entry under TWikiUsers.
2. If you have both an external account and a CERN account on CERN machines (lxplus etc), you should use the CERN login if you do not have write access with your external account. (As a test, you can try to edit something in the Sandbox web.)
3. Please note that if your email address or CERN account details change this must be reflected in the TWiki registration. For CERN accounts the update will be done automatically but external users should request the change in the IT service-portal
4. If you have access to TWiki, but not to pages with protected content, please contact the owners of these pages so that they can grant you access. You may need to be a member of a particular TWikiGroups or a CERN e-group in order to access some webs. (Please see TheLHCexperimentsWebs for more information.)

It is your local TWiki documentation manager who decides about access control, not TWiki support in IT.
