Hi,
I believe this patch might help with the MD5/SHA1 migration "issue" of
user passwords.
It adds a auth backend for the user.prefs file, the result is that the
first time a user
authenticates with Pootle the password matched is used to insert the new user.
Please test. This was hacked up in 2 minutes. Also feel free to adjust
the wording.
