Native Subversion Client setting will not save the authentication in cache causing authentication error

XMLWordPrintable

      Summary

      If FishEye/Crucible is configure with Native Subversion Client and the Subversion server is using NTLM authentication, FishEye/Crucible does not cache the credential of the user in the repository setting.

      Actual Results

      FishEye/Crucible keeps on getting the password from the repository setting till it hit the maximum count ("SVN is requesting password too often"). When it hits the maximum count getting the password, FishEye/Crucible will not get the password from the repository setting anymore causing the request to have authentication error:

      From the above example error, FishEye/Crucible is started by the user "klfoong" and using the credential for the user "klfoong" in the repository setting to have NTLM authentication with Subversion server.

      However, due to the credential is not cached, FishEye/Crucible keep on getting password from the repository setting till it hit the limit and stop getting password from the repository setting which will have authentication error during the request.

      Expected Results

      FishEye/Crucible should save the user "klfoong" credential in the cache if Native Subversion Client is used.

      Solution

      Atlassian Update – 19 Dec 2022

      See this KB article: https://confluence.atlassian.com/fishkb/fisheye-and-ntlm-1189783826.html

      Workaround (deprecated)

      As a workaround, we will need to login to the machine hosting FishEye/Crucible as user "klfoong" and perform a simple command like "svn info http://subversion" so that the credential will be cached in "C:/Users/klfoong/AppData/Roaming/Subversion".

      However, if there are hundred repositories in FishEye/Crucible with different Subversion domain, we need to run the same "svn info" command for all those repositories with different Subversion domain. (This is how Native Subversion Client save the credential. It save it based on host name.) In this case, the following Python script can help:

      #!/usr/bin/python

import os
import sys
import getopt
import subprocess
import xml.etree.ElementTree

def main(argv):
    opts, args = getopt.getopt(argv,"hc:")
    for opt, arg in opts:
        if opt == "-c":
            config = arg

    print 'Using "' + config + '"'
    print 'Processing repositories:'

    root = xml.etree.ElementTree.parse(config).getroot()
    for repository in root.iter('repository'):
        svn = repository.find('svn')
        if svn is not None:
            auth = svn.find('auth')
            url = svn.get('url')
            if auth is not None:
                username = auth.get('username')
                password = auth.get('password')
                devnull = open(os.devnull, 'w')
                info = subprocess.call('svn info ' + url + '@HEAD --non-interactive --username ' + username + ' --password ' + password, shell=True, stdout=devnull, stderr=devnull)
                if info == 0:
                    print '[DONE]', url
                else:
                    print '[FAIL]', url
            else:
                print '[SKIP]', url, '(no auth)'


if __name__ == "__main__":
    main(sys.argv[1:])

      This Python script will parse config.xml and execute svn info command against each SVN repository that has credentials defined. This should generate the files in svn.simple directory automatically, so it won't be needed to run that command manually anymore, for each repository.
      To run this Python script:

      python PATH_TO_PYTHON_SCRIPT -c PATH_TO_CONFIG_XML

      To make it worse, if the user "klfoong" password in Active Directory needs to be changed periodically, we will need to run the "svn info" command for all those repositories again.
