Today, this bit me in the ass. I've been experimenting with using bzr
local branches with an SVN upstream server at work. This has been working
quite well. However, my company's security policy requires changing my
domain password every 3 months. Today was that day and now bzr prompts me
for my SVN (which is mapped to the domain auth) password every time I try
to commit because it still has the old password in the svn saved auth
info.

The only way I can see to resolve this currently is to make a commit to
that SVN server using the standard SVN or TortoiseSVN client which will
update the saved auth info.

If bzr-can read the saved auth info, why can't it update it as well?
