Notes for read access restriction:

  • Read access restriction only works if the view script is authenticated, that means that users need to log on also just to read topics. TWiki Installation has more on basic authentication based on the .htaccess file.
  • There is a workaround if you prefer to to have unrestricted access to view topics located in normal webs, and to authenticate users only for webs where view restriction is enabled:
    • Leave the view script non authenticated in the .htaccess file.
    • Enable the $doRememberRemoteUser flag in wikicfg.pm as described in TWiki Authentication. TWiki will now remember the IP address of an authenticated user.
    • Copy the view script to viewauth (or better, create a symbolic link)
    • Enable authentication for the viewauth script in the .htaccess file.
    • When a user accesses a web where you enabled view restriction, TWiki will redirect from the view script to the viewauth script once (this hapens only if the user has never edited a topic). Doing so will ask for authentication. The viewauth script shows the requested topic if the user could log on and if the user is authorized to see that web.
 
  • If you enable view restriction for a web, it is recommended to restrict search "all webs" from searching this web. Enable this restriction with the NOSEARCHALL variable in its WebPreferences, like:
    • Set NOSEARCHALL = on
  • It is not recommended to restrict view access to individual topics since all content is searchable within a web.
View topic | History: r36 < r35 < r34 < r33 | More topic actions...
