[SOLVED] how to add a new user account for an existing SVN-subversion server?

how to add a new user account for an existing SVN-subversion server?

I have an existing SVN server and I need to add more users to connect using subversion clients to do checkout, updates and commits. I read documents (http://svnbook.red-bean.com/en/1.7/svn.serverconfig.svnserve.html#svn.serverconfig.svnserve.auth.users) on how to adding new users to the svn server but I couldn't get a good idea. Please somebody just help me to find out the correct way to add new users and grants privileges.

my problem is I have a SVN server with user "aaa" with administrative privileges. I need to add an another user call "bbb" with same privileges.

Can svn commands use to create new user account after set-up the SVN Server ?
or do I need to manually edit existing .conf file to add new users for SVN server ?

Server OS is CentOS 6.3

Solution

As Rup explained in the comments. I found /etc/svn-auth-conf and list all existing users. Then added a new user using below

htpasswd -m /etc/svn-auth-conf <userName>

then new password, and password confirmation are prompted. its worked.
