You must change two files passwd and svnserve.conf.
For examples :
1. svnserve.conf - You can copy all body of this file into your
repository's svnserve.conf file.
#>>> Begin of svnserve.conf file
### This file controls the configuration of the svnserve daemon, if you
### use it to allow access to this repository. (If you only allow
### access through
http: and/or file: URLs, then this file is
### irrelevant.)
### Visit
http://subversion.tigris.org/ for more information.
[general]
### These options control access to the repository for unauthenticated
### and authenticated users. Valid values are "write", "read",
### and "none". The sample settings below are the defaults.
anon-access = read
auth-access = write
### The password-db option controls the location of the password
### database file. Unless you specify a path starting with a /,
### the file's location is relative to the conf directory.
### Uncomment the line below to use the default password file.
password-db = passwd
### The authz-db option controls the location of the authorization
### rules for path-based access control. Unless you specify a path
### starting with a /, the file's location is relative to the conf
### directory. If you don't specify an authz-db, no path-based access
### control is done.
### Uncomment the line below to use the default authorization file.
# authz-db = authz
### This option specifies the authentication realm of the repository.
### If two repositories have the same authentication realm, they should
### have the same password database, and vice versa. The default realm
### is repository's uuid.
# realm = My First Repository
#>>> End of svnserve.conf file
2. passwd - You can copy all body of this file into your repository's
passwd file.
But you must replace "harry" and "sally" on real users and also you must
change them passwords.
#>>> Begin of passwd file
### This file is an example password file for svnserve.
### Its format is similar to that of svnserve.conf. As shown in the
### example below it contains one section labelled [users].
### The name and password for each user follow, one account per line.
[users]
harry = harryssecret
sally = sallyssecret
#>>> End of passwd file
