Original GitHub issue: https://github.com/modoboa/modoboa/issues/2036

I have no idea how widespread this might be, but there is an issue with passlib in certain scenarios under Python 3:

For some reason cryptography calls on my system return a bytes-like object and not pure strings, which results in a passlib error. Passlib is used by Django e.g. for logging in to modoboa.

I've reported the issue upstream (https://bitbucket.org/ecollins/passlib/issues/113/errors-handling-cryptcrypt-returning-byte), but would require an update in the dependency tree.

For now I fixed this "manually" in my site-packages. Might be a gotcha for PyPy3 installations as well.

Quick update: Passlib has fixed this in v1.7.3. One possible fix is to force-upgrade passlib to this version.

@PatTheMav I think this issue should be moved to the main repository. What do you think?

I agree - iirc modoboa itself has the dependency.
