Environment

Lifecycle Manager 8.x

Aria Automation 8.x

Cause

This issue occurs when vIDM has two user accounts which match the system domain admin account (such as configadmin) which is trying to perform the vracli vidm set task. For example, this issue will arise if there is a system domain admin account (such as configadmin) and an Active Directory user also named configadmin which is synced within vIDM

Resolution

To resolve this issue you will need to remove the Active Directory user from the domain sync settings which has the same name as the system domain account name. After the Active Directory user has been removed from vIDM you can complete the Aria Automation deployment from Lifecycle Manager
