How to update IPAM credentials

Hi All.

We are beginning to use IPAM in my environment.  Using a service account with permissions to our DHCP servers.

It appears that, to add a DHCP server to IPAM, you need to enter a credential and cannot use an existing embedded Windows credential.  No problem I did that.

However... we need to update our service account passwords on a regular basis.  Poking around IPAM I can't find where you update the credential (service account password).

Can someone offer guidance on the best way to update the IPAM credential?  Thanks.
