Refactoring Proposal: Registration should not be in the TWiki Web.


Man reasons but principally:


The refactoring is strainght forward.

The Registration form & supporting code references are moved from the TWiki web to the Main web.

Impact and Available Solutions

WhatDoesItAffect: Auth, Refactoring, Documentation

Note: Patch is attached as http://twiki.org/p/pub/Codev/RegistrationShouldNotBeInTheTWikiWeb/twiki-foo-bar-patch.diff. The patch is against the TWikiAlphaRelease of 15 Feb 2004.


Some small chage to the documetnation is required.


No APIs are affected by this change.


Trivial. No actual change to code is required.


This is really a rationaliztion. The TWiki web is about documentation and configuration. All the user topics, groups, supporting tables are in the Main web. That is where registration ends up. It is also where registration should start.


I'd like to add to the mix the idea that users can be defined in more than one web - basically, i'd like to have a Users web for the admins, a Shop/Users web for users of the Shop, and Bugs/Users for users able to report bugs, and natrully, to be able to combine the users from multiple webs to give them all access to the Sandbox web smile

makes me wonder if active topics like this shouldn't be in something akin to the templates web, as they are very similar to the Attach screen, the 'more actions' page etc...

What you are describing, Sven, is perilously close to RBAC - role based access control.

I much prefer RBAC for a number of reasons. Principally its a lot easier to administer than access control lists. With a large user base ACLs can get very long and difficult to administer (as well as verify, debug and audit). RBACs are much simpler: "This is what this role can do" A user can have more than one (zero?) role if necessary. RBACs are much easier to administer and are O(#of Roles) rather than O(# of users) from a performance POV.

While ACLs are straight forward to program - that's why historically they are so common - RBACs are more business orientated and in fact no harder to program. It is not a new technique, it was documented first back in the mid 1970s. I've used it myself in a number of database applciations. See http://csrc.nist.gov/rbac/ for details as well as an implementation example.

However this is quite separate from the issue of this topic, that .... Registration should not be in the TWiki Web.

I concur: Registration should not be in the TWiki web.

I am about to disable registration on a site I am administering - and because the text I need to change is in the TWiki web I'm changing stuff that should be immutable.
