Hi Riccardo, riccardo grazioli wrote: I'm afraid this won't be easy and/or fast! But, just in case you are not aware of this, have you visited jira.xwiki.org? If you look for "authentication" here http://jira.xwiki.org/jira/secure/QuickSearch.jspa, you will get a bunch of related entries. I think several of them could apply to your case. To the best of my knowledge, XWiki in its current state of development support basic authentication but username and password can not be passed with an URL yet. As a web developer I am sure you will be easy to follow the already created Jira issues! HTH, Ricardo -- Ricardo Rodríguez Your EPEC Network ICT Team

You mean like /xwiki/bin/login/XWiki/XWikiLogin?j_jusername=XWiki.Username&j_password=xxxx ? Because this works :) Jerome.

Please, allow me to put an example. How do you pass username and password in the URL to access this document? http://xepecnet.environmentalchange.net/xwiki/bin/view/ICT/RGraphicSample01… username dummy, password dummy is has view rights on it. It will be great if you could help me with this issue. Thank you so much. Best, Ricardo -- Ricardo Rodríguez Your EPEC Network ICT Team

I'm very glad to hear that :) A while ago I started documenting XWiki URL and forms mappings to make it easier finding out this kind of URLs : http://dev.xwiki.org/xwiki/bin/view/Drafts/XWikiURLMappings. I really need to find some time to complete this draft. Regards, Jerome.

I am just to create my own mental map about how XWiki is constructed and how will be the future... As for the proposed link, it access the document without a glitch, but it fails to be the option I need as parameter for a R function. Of course to deal with this R function is an option, so it is not only a XWiki issue, but I am guessing if I explain you the situation it will be possible to find an option within XWiki itself. Please, look at this: This R command works fine if unregistered users are allowed to view ICT.RGraphicSample01... source("http://xepecnet.environmentalchange.net/xwiki/bin/loginsubmit/… If I prevent unregisterd users to view this file, here the error... source("http://xepecnet.environmentalchange.net/xwiki/bin/loginsubmit/… Error en file(file, "r", encoding = encoding) : no fue posible abrir la conexión Además: Warning message: In file(file, "r", encoding = encoding) : no fue posible abrir: el status HTTP fue '401 Unauthorized' Even though part of the message is in Spanish, I thing it is clear with a 401 error http://xepecnet.environmentalchange.net/xwiki/bin/loginsubmit/XWiki/XWikiLo… Accesses correctly the document in any case. Could you figure out why? My happiness will be almost complete... until I move to the next issue :-) Thanks for your time and your help! Ricardo -- Ricardo Rodríguez Your EPEC Network ICT Team
