I manage a Last Pass Enterprise instance at work. I love/hate it. The interface is terrible and buggy. However, it's the only tool I've found to manage passwords across many users (some medium to non-technical) who need access to shared accounts within an organization. 1Password doesn't really do this, and sharing vaults over Dropbox doesn't really cut it. Despite all the bug pain, it's so much better than what we were doing before, sharing passwords via email and other embarrassing methods.
How can there really only be one company doing what LastPass Enterprise does? There must be other systems that I just can't find in my research. Any recommendations for other managed password stores for organizations?
