When you say user accounts, are you referring to privileged accounts or standard user accounts?

You can use directory queries and smart rules to automatically onboard the privileged accounts and enable password rotation.

Hello Prudhvi,

These would be for both types of privileged accounts and standard user accounts. Do you have any sample templates, if possible, for this automatic integration? Thank you very much.

​@Carlos Mendonça I don't have any sample templates that I can share, below are the few articles you can refer to.

Never add standard user accounts as managed accounts, only privileged accounts should be added as managed accounts.

Don't add all user accounts from AD to managed accounts. Instead use the filtering in directory queries and add those accounts which are in-scope of privilege access management.

Based on your initial question, you will need to “map” standard user accounts to their privileged accounts at some point. Here is a helpful KB article (with video) that explains this process.
