Lot of open source and commercial projects are working on the version control system like SVN,CVS.These days i was tried to configure CVS in my company local server(Linux-Fedora Core).For that purpose, i was searched lot of article about the CVS configuration but couldn't find any good article about "How to add user to SVN" but finally i did it completely.I write down it because it may be helpful to others. Step 1. check your CVS folder #echo $CVSROOT step 2. It is possible to have cvs users which are not part of the OS (no local users). This is actually probably wanted too from the security point of view. Simply add a file named passwd (in the CVSROOT directory) containing the users login and password in the crypt format. This is can be done with the apache htpasswd tool. Note: This passwd file is the only file which has to be edited directly in the CVSROOT directory. Also it won't be checked out. More info with htpasswd --help # htpasswd -cb passwd prabath password...
