We are a team of IT people who manage passwords for clients. We not only accept shared passwords but also share out passwords externally with our partners.
It becomes a cluttered mess because we can't accept shared passwords into a shared folder, or even a named folder. When sharing out bound, the clients have the same problem.
I know there are products out there like "Passportal" that manages client passwords, but it would be great if LastPass incorporated features better suited for the management of external partner passwords.
