Protheus allows integrating the Protheus user login with the AD (Active Directory) network user. Then, you can link a Protheus user to an AD user, and then Protheus will accept the login by the network user.

To configure, proceed as follows:
- Access Configurator > User > Passwords > Policy.

- On the first tab (Security Policy/Password Rules), change the option "Enable single sign-on" to Required (if you want to force Single Sign-On with AD for all users) or Optional (if you want to allow users to log in with their own Protheus user and password, or use the network user).

- In "Single Sign-on Mode", select Active Directory and click Confirm.

- Access User Registration (User > Passwords > Users).

- Click on the user, then click Change.

- On the main tab (User), click on the Active Directory tab.

- Double click under the "Domain" column and enter the network domain of your AD.

- Double click under the "User" column and enter the network user login that will be linked to this Protheus user.

- Click Confirm.

- After setting, when opening Smartclient, the domain\username will appear by default. If you type the password of this network user, it already enters the Protheus user linked to it.
