LDAP integration status
by Jiri Luzny 29 Apr '05

29 Apr '05

Hi, as we plan to integrate XWiki user management with Active Directory in our company, I'm curious what is the status of LDAP Integration. Is it testable? If so, I would be happy to become a beta tester for this ;-) Jiri.

cruisecontrol build server setup
by Ludovic Dubost 29 Apr '05

29 Apr '05

Hi All, The Cruisecontrol build server is now setup and the build currently passes. Currently tests failures don't make the build fail because there are some tests that fail for cruisecontrol setup reasons. See results at http://build.xpertnet.biz LDAP fails because there is no LDAP server setup. The Servlet authentication fail because there is a issue when running these tests on the Linux build machine (on Windows it works). This must be due to a cookie issue in the test environnement. Other tests need to be looked at. Builds are only redone if there are SVN changes. email notifications to the developers list are not yet setup. This should be the case pretty soon.

Hi, Here is a summary of UBS's evaluation of XWiki versus other wiki tools. I've responded to them. It's very interesting for us to have other people's view on XWiki.
