Explanation:
https://docs.microsoft.com/en-us/advanced-threat-analytics/ata-prerequisites
A user account of a user who has no network activities.
This account is configured as the ATA Honeytoken user.
To configure the Honeytoken user you need the SID of the user account, not the username.

https://docs.microsoft.com/en-us/advanced-threat-analytics/install-ata-step7
ATA also enables the configuration of a Honeytoken user, which is used as a trap for malicious actors – any
authentication associated with this (normally dormant)
account will trigger an alert.
