Looking for a web based password management system
 

'm looking for a web based password manager for multiple users, that can be used on a local intranet. Basically I need something that has different access groups, for example:

employees
supervisors
managers

Each group would have a global login and would provide access to certain levels that the group is allowed to see. Allowing the end user to add/change passwords to their particular access group would be a plus. Searching would be a bonus

It would be going on a Linux/apache system if that makes any difference

Anyone have any recommendations?

Wouldn't Webmin do the trick?
