If you are using Eclipse IDE and using SVN as repository for your projects then you might be aware of subclipse and subversion plugins. Just to give a brief idea, these are the plugins to work with SVN in Eclipse IDE for version controlling.
Recently I faced a problem in using it for multiple users. When we connect to SVN repository from any user id and then saves the password, it caches this data to a hidden file in the file system. So when you connect to some other project location, it doesn’t prompt for user/password and gives error message. To avoid this error, we need to clear the saved data.
