Re: how can I change my password by SVN client?

My whole point was that Subversion doesn't force you to use a built-in
security scheme.

YOU are free to choose the system YOU want for passwords. We use LDAP and
Apache. You can use ssh keys, wallet, kerberos, or simply store the
information in a text auth-password file and use plain old "svn". Exactly
how you do your security is up to the site.
