Can we lock down user admin functionality to allow password changes only?

Question

Hi,
Is it possible to lock down the user admin functionality so a specific role can only change passwords?
We have a large user base of >10K infrequent users that are forced to change their passwords every 30 days. We suspect a lot will require password changes and we are keen to not have the tech team spending most of their time dealing with such requests. We would like to pass this task onto data management but not allow them the system administrator functionality.
We know we can create a responsibility with a limited menu available so the operator can see only the security/user/define menu. But this will still allow the person to add responsibilities to existing user accounts and create new user accounts, both of which are deemed unacceptable security risks. Is it possible to lock down the form as well as the menu? Allowing operators to only change the password of existing users? Or can we use the custom.pll to error when a user tries to do anything except edit the password field when in this role?
Thanks
Matt

You should be able to do that. You would create a new privilege level (ie 7), assign all commands to that level except (this is my guess) the command vpn-sessiondb, you would put that at a lower privilege level (ie 6). Here's a write-up that may help getting you in the right direction.
