Technical Tip: 'Duplicate Entry Found' error when creating an administrator user

Why the Duplicate Entry Found error occurs:

• In FortiGate, the Wildcard option allows any user from a specified remote group (e.g., GRP_ADMINISTRATORS) to authenticate without the need to create a manual administrator account.
• When a user from that remote group tries to log in, FortiGate automatically recognizes them as an administrator based on the group membership.
• If an administrator attempts to manually create a user with the same name as an existing user in the remote group, FortiGate detects a conflict because that username already exists dynamically via the Wildcard mechanism. This results in the Duplicate Entry Found error.
