Question

Hello,

when I restrict a web with ALLOWTOPICVIEW to a group of users, the Revision History denies view access, even if I am Main TWiki Administrator. Any idea, what I meade wrong? JR

Added Comment from JensRoeder:

I found out that the rdiffauth does work properly, only the switching from rdiff to rdiffauth does not. When checking the sent output, the Moved redirection leads to the deny oops:

Location: [...] /bin/oops/Termine/WebHome?template=oopsaccessview

instead to the rdiffauth. Any idea, why?

Answer

It looks like your installation does not track users, so rdiff always sees just TWikiGuest, also if it is you. Enable partial authentication (TWikiUserAuthentication or track the user with cookies.

I have had a similar problem from beginning, but never got time to diagnose it. Today, I looked at it bit closely.

The '>' links and 'Total page history' links on Topics controlled by either ALLOWTOPICVIEW or ALLOWWEBVIEW go via 'rdiff' instead of 'rdiffauth'.

.../twiki/bin/rdiff/KnowledgeBase/MyTopic?rev1=1.53&rev2=1.52

If I just change cut-n-paste the above URL in my browser and change 'rdiff' to 'rdiffauth', I get the expected results.

So, the '>' and 'Total page history' link generation in 'view' code needs to be fixed to use 'rdiffauth' instead of 'rdiff' when handling the protected topics (e.g. via ALLOWTOPICVIEW or ALLOWWEBVIEW).

Just to confirm Peter Thoeny comment. When I do a compare revision, I get the Revision 17 is unreadable message in the result comparison page.

The access rights in my WebPreferences are set as follow:

#Set DENYWEBVIEW =
Set ALLOWWEBVIEW = TWikiAdminGroup , SAAMDeveloppersGroup, SAAMReadOnlyGroup 

The data/logxxxxxx.txt file does show rdiff being executed on behalves of TWikiGuest:

| 19 Jul 2007 - 15:16 | TWikiGuest | rdiff | SAAM.WikiSaamInstallationGuide | 6 5 Mozilla | 153.98.68.197 |

If I add TWikiGuest to the Set ALLOWWEBVIEW the problem disappears. (This is a quick fix and I really should follow Peter's recommendation if I want to keep my access rights as before)
