Ask HN: Server Management Software

Has anyone used BMC's bladelogic product? Does anyone know any alternatives? I'm basically looking to see if their is any product out there like that, where I can use roles to control access to servers, where the user can login via putty/ssh. I'm not looking for a password management solution, but more of a role/user solution. I dont think chef/puppet/ansible have this ability. You can run remote commands and such, but I dont think I could use that to pull up logs and work as if I was on an ssh session on the server. Might be wrong on that though.
