Description

Remove the password from the cppm user command. I was seeing this with Aruba Access Points using the instant model with the virtual controller. This command is used to configure access for fetching downloadable user roles from ClearPass and may not be commonly used yet.

I searched the open issues and exiting pull requests and did not see any related to this yet. I hope this meets the requirements for a pull request and can help someone else better benefit from Oxidized.
