Problem Statement

Anyone using a Subversion server such as VisualSVN might require that NTLM/IWA is used.

Currently SVNKit does not support NTLM. A Native SVN Client is required.

Fisheye using native SVN eg. SlikSVN or Wandisco

Ensure the user running Fisheye is a user that can authenticate against the Subversion server, e.g. a user present in the Active Directory that the IWA is using.

• Be sure the user is using the credentials Active Directory is expecting
• By default Fisheye running on Windows will install and run as 'Network Service'. In such case switching to a regular account in the service configuration is needed. Open the 'Services' panel in Windows, open properties for the 'Atlassian Fisheye' service, access the 'Log On' tab and change the user:

• With this configuration the username and password in the Fisheye UI can be left blank
• This configuration also bypasses the check which limits how often the password is used - see FE-5329 - Getting issue details... STATUS

Caveats

It might be tough to find an native SVN client for several reasons:

• WANDisco only offer 32 bit binary
• SlikSVN does not bundle a jar with the dll
