Hi Marius, There are a lot of AJAX requests, some work, some don't. All requests have cookie headers. But it looks like the failed requests have no authorization header, and the other requests do have one. On the main page I see some failed requests (without authorization header) and right after, the same request again with authorization header that succeeds! Looks like some kind of retry. With the REST request, I do not see this duplicate requests.

All AJAX requests should have all the cookies that the main request (for the edit mode) has. So if the authentication information is stored in cookies then it is send with the AJAX requests. The first thing to check is if the AJAX requests (logged in the Firebug console) have the authentication information. I don't know how the Kerberos SSO works nor if it integrates well with REST. We need the help of a REST guru here :) Thanks, Marius On Thu, Mar 14, 2013 at 1:37 PM, Mark Jas <mark(a)nieuwenborg.nl> wrote: > Forgot to mention: > Catalina.out shows me this: > > 2013-03-14 12:35:58,430 [http://xwiki/xwiki/bin/get/Main/WebHome?xpage=xpart&vm=commentsinline.vm] WARN a.t.TrustedLDAPAuthServiceImpl - Failed to resolve remote user.

TRANSPORT_ERROR normally happens when a request made by the tree fails (usually because the URL is bad). The tree uses the REST system to fetch its data, so all requests made by the tree are /rest/ requests.

[xwiki-users] Database indexes for XWiki 3.5
by Jeremie BOUSQUET 13 Mar '13

13 Mar '13

Hello guys, I'm checking page about database administration [1], as I would like to "sanitize" a bit my indexes before going futher with migration to 4.x. (reason is that clearing problematic data from my stats tables takes forever, and I think it could be improved with the correct indexes). >From that page [1], I get the full list of indexes created for xwiki < 3.2, and the list of indexes that can be created manually, adding to the indexes created automatically by XWiki. But the info I would like, is the list of indexes that I should expect to be created when on XWiki 3.5. My purpose, is that my "show index" from xwikistatsvisit, for example, displays a number of duplicate indexes, some using lowercase others uppercase (waste of space to the least). Also apart from duplications, I'm now unsure that there are no excessive indexes created to start with (8 indexes on a table seems a bit too much, but I'm no DBA and xwiki schema is particular). I could install another xwiki 3.5 instance, on an empty database, and check the indexes, but if there is a way to find it from the code I'd clearly prefer ;-) So if you have any pointer on the right location, that would be very nice. I'm on MySQL 5.1 by the way. Thanks & regards, Jeremie [1] http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Database+Administration…

[xwiki-users] migrate single spaces
by DrSarez 13 Mar '13

Hello, i have installed the latest XWiki 4.5.1 with the debian package and installed all content via the new application manager. But now I have an old XWiki 3.5 instance I want to migrate several spaces from. I tried to export the wiki as xar and import it again. But the xar file is over 70mb large and the importer would not accept this large file. I tried the plugin 'large xar imprter' but it did not work. So how can I migrate my spaces from the old xwiki to the new one? They contains just simple pages with text content and some attachments. -- View this message in context: http://xwiki.475771.n2.nabble.com/migrate-single-spaces-tp7584247.html Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] Allocating memory
by Matt Lamoureux 12 Mar '13

12 Mar '13

Hi all, I admit that I am a Tomcat rookie. That being said, I have been struggling with out-of-memory/permgen issues for a while now with no progress. I have looked at this: http://www.xwiki.org/xwiki/bin/view/FAQ/HowToSolveAJavaHeapMemoryError ...but I have not been successful in adjusting my settings. I am running on Windows 2008 R2 64-bit with 12gb available RAM. I am trying to allocate at least 4gb to run Xwiki, since nothing else is running on this server (other than MySQL). I run Tomcat as a service, if that matters. I have been using the Groovy function "${Runtime.getRuntime().maxMemory()}" to keep an eye on my heap size. It stays at 259522560 bytes (247.5mb) no matter what I do. I have tried setting a CATALINA_OPTS system variable with the following settings: -Xms2096m -Xmx=4096m -XX:MaxPermSize=1024m -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled I have also tried going into the Java tab on the Tomcat properties window and setting the values there: -DXms2096m -DXmx4096m -DXX:MaxPermSize=1024m -DXX:+CMSClassUnloadingEnabled -DXX:+CMSPermGenSweepingEnabled So what am I doing wrong? Or is it my understanding that is off - is that Groovy function not really telling me the allocated memory? Any advice would be greatly appreciated. Thanks! - Matt L.

Hi xwikiers, I just released a new authenticator on http://extensions.xwiki.org/xwiki/bin/view/Extension/XWiki+Authenticator+Tr… . * extract the user id from the remote user and automatically create related XWiki user profile * allow using different LDAP configuration depending on what is in the remote user * synchronize user related information and group membership from LDAP (use the standard LDAP authenticator for this actually) Enjoy :) -- Thomas Mortagne
