Hi, I'm using v0.9.840 with j2sdk-1.4.2_06 authenticating against OpenLDAP. It works but for the known problem where "Login of local XWiki user (not in LDAP) doesn't work when LDAP auth used" [bug, key: XWIKI-72]; So, I'd like to try the code patch provided on that jira page. However, I'm just an admin and tho I installed ant and downloaded the xwiki source code (and placed that .diff patch next to its target), I didn't get very far out the door: [no@nowhere xwikisrc]$ ant -debug Buildfile: build.xml BUILD FAILED /home/no/xwikisrc/build.xml:126: taskdef A class needed by class org.apache.cactus.integration.ant.CactusTask cannot be found: junit/framework/Test I read-up on this and figure that I need junit and maybe to learn ant, but at this point I must ask: if I start using this patched version will I go down an un-upgradable branch of code and hose my content when I upgrade next? can I just switch out the existing LDAPAuthServiceImpl.class in my xwiki install with a patched version without having to rebuild the whole app? and, can anyone point me to an XWIKI-72-patched version of that class b/c I see that merely javac'ing the LDAPAuthServiceImpl.java file doesn't work (cannot resolve symbol errors :) ...if the answer to all of these is "no" I'll just keep trying to build from source, so not too much hand holding needed. thanks for your help, Ken
