Last, but not least, is the fact that Bamboo uses
DefaultSVNAuthenticationManager. Personally, I think that it would be
not only safer, but also more "correct" to use custom implementation of
ISVNAuthenticationManager - this will allow to store all credentials
within Bamboo application, not as something belonging to the user. It
would be also much easier to configure repository access credentials
from Bamboo user interface and there will be no problems like [one we're
discussing currently|http://jira.atlassian.com/browse/BAM-4517] (though of course it should be fixed!).
