Question

AccessControlException: Access to CHANGE Main.xxxx for TWikiRegistrationAgent is denied.

Getting this error when clicking SUBMIT from the Main/TWikiRegistration page. This is with 4.0.1. As a result cannot register new users.

Answer

I added TWikiRegistrationAgent to Main.WebPreferences as follows

• • Set ALLOWWEBCHANGE = TWikiAdminGroup, TWikiRegistrationAgent
  • Set ALLOWWEBRENAME = TWikiAdminGroup, TWikiRegistrationAgent

and that seemed to let it clear the access hurdle.

That works, yes. Actually, it is just needed for the TWikiUsers topic, e.g. add the TWikiRegistrationAgent to the ALLOWTOPICCHANGE of Main.TWikiUsers.

I had the same problem in my local installation of TWiki - and TWikiUsers topic already had line

Set ALLOWTOPICCHANGE = TWikiAdminGroup, TWikiRegistrationAgent

it did not work.

But when I added, as DickWieland adviced, TWikiRegistrationAgent to the WebPreferences, the registration worked again.

Something wrong with the TWikiUsers? What I have noticed, in WebPreferences page, it was like %MAIN_WEB%.TWikiRegistrationAgent, but in the TWikiUsers page, it was just TWikiRwgistrationAgent. Could this be the problem?

I am having this same problem, and I already have this line in my Main/TWikiUsers.txt file:

   * Set ALLOWTOPICCHANGE = TWikiAdminGroup, TWikiRegistrationAgent

If I recall correctly, the TWikiRegistrationAgent needs access to the Main web (ALLOWWEBCHANGE in Main.WebPreferences) so that he can create the user home pages for the newly registered users.

I believe this is correct.

Make sure that your data/Main dir in writable and owned by apache owner ( if you are running apache)

I have a similar issue, but get:

_Access check on Main.XXXX failed. Action "CHANGE": access not allowed on web.

I have these settings on WebPreferences and TWikiUsers

   * Set ALLOWWEBCHANGE = Main.TWikiRegistrationAgent
   * Set ALLOWTOPICCHANGE = Main.TWikiRegistrationAgent

(Respectively). Does TWikiAdminGroup need to be included? Do I need the MAINWEB declaration in front of TWikiRegistrationAgent? I have been fighting this for a while. I just want to lock down my Main web for changes (but allow viewing by anyone).

Thanks in advance.

Try adding the user TWikiRegistrationAgent to the TWikiAdminGroup. Fixed it for me whe I ran into this.
