We are looking at lastPass - looks good so far. (enterprise Ed)
IronStratus is another one to check out lets users keep their own personal passwords and grant access to apps passwords by an admin.
I personally prefer 1password - but it's really single user oriented.
Obviously different from I'd/auth providers like okta or ping identity...but i find there are so many accounts/passwords shared in organizations for services that these guys may not support. (apps with no SSO services for example). Yes, they have some password management tools but they don't seem to have in app/browser shortcuts (ie:chrome/ff extensions).
