We installed jenkins as described here:

https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu

On a fresh installed Ubuntu 12.04 LTS 64bit system.
If I try to configure a job with a svn repository via https, which has no anonymous access, I got the message "unable to access https://svn...." for no svn access.

After clicking the link "enter credential"
( http://devbuild.bla.at:8080/job/test/descriptorByName/hudson.scm.SubversionSCM/enterCredential?https://svn.bla.at/repos/XYZ/trunk/kkms )

I filled in my username and password and press OK.
I got this error:

In the svn webserver access.log I got a request with this svn user (qaOWQ8w3-byHudson):

192.1xx.100.1xx - qaOWQ8w3-byHudson [08/May/2013:15:41:54 +0200] "OPTIONS /repos/XYZ/trunk/kkms HTTP/1.1" 500 431 "-" "SVN/1.7.6 SVNKit/1.7.6-jenkins-1 (http://svnkit.com/) t20121220_1647"

which is not permitted on this svn repo.

Additionally I would expect that my entered credentials get stored in hudson.scm.SubversionSCM.xml file. But here was nothing added!

In the jenkins system log I found aslo some problems:

I would expect that on a fresh installed Ubuntu with fresh installed jenkins, that (authenticated) https svn access should be working fine, and my credentials are stored somewhere in jenkins.
