On fresh installation of hudson 1.214 when creating a job and configuring the
subversion repository URL. When leaving the field I am asked to enter the
credentials. I do so specifying user name and password. Clicking OK says:
Authentication was successful. Information is stored in Hudson now.

But looking into the directory, there is no file:
hudson.scm.SubversionSCM.xml

Going back to the configuration page, it says always:
No credential to try. Authentication failed

Installation on Fedora Core 8. Hudson has write access to the directory (there
are other files such as config.xml and from various plug-ins). Running with java
1.6.0_06, starting the hudson with: java -jar hudson.war

There is no output on the console when configuring, however there are exceptions
when trying to authenticate:
org.tmatesoft.svn.core.SVNCancelException: svn: No credential to try.
Authentication failed
