Mavlarn. Please find out the custom realm setting way.
<!-- used for svn access -->
<http realm="svn" pattern="/svn/**" access-decision-manager-ref="accessDecisionManager">
<intercept-url pattern="/svn/**" access="A, U, S" />
in applicationContext-security, there is the above section. It uses "svn" as a realm, realmn is a kind of sub category of the security area. So. SVN client keeps the ID/PW per realmn,
Currently... only svn realm is provided when accessing svn repo. It might be better to provide the user id as realm. Please check if there are a way to define custom security setting which dynamically set the realm depending on the URL.
For example.. if a user access
user1 should be realmn for this URL.
