Defining Default HOPEX Authentication Mode
By default, authentication is managed within HOPEX platform.
*Configuration of authentication delegated to a third party service is described in Installation and Deployment > HOPEX Unified Authentication Service documentation.
Viewing default authentication mode 
In the environment options, you can view and modify the default Defined Authentication Mode.
To view default authentication mode:
1. Access environment options.
2. In the options tree, expand the Installation folder and select User Management.
3. In the right pane, view the value of the Authentication Mode option.
By default at installation, "Standard" is the authentication mode, it is the MEGA authentication mode.
Defining default authentication mode to LDAP 
When you define the default authentication mode to LDAP, users are managed in an LDAP directory and authentication is managed by the LDAP directory.
When you change the default authentication mode while users are already created, these users keep their defined authentication mode.
*To change the authentication mode of a user, see Modifying a user authentication mode.
However, if you define the default authentication mode to LDAP, at authentication, whatever the person, the authentication service checks if the person belongs to LDAP. If the answer is:
• yes, the person is authenticated via LDAP.
• no, the authentication service checks on the login of the person if another authentication mode is defined.
*See also the full authentication diagram (including person groups): Mapping Diagram.
To define default LDAP authentication mode:
1. Access environment options.
2. In the options tree, expand the Installation folder and select User Management.
3. In the right pane, for:
• the Authentication Mode option, select "LDAP" value.
• the Default writing access area for LDAP import, select the writing access area you want to define to the persons at LDAP import.
Modifying a user authentication mode 
User authentication mode is defined on the login by the Authentication Mode parameter. The value of this parameter is inherited at user creation from the value of the Authentication Mode option defined in the environment options (see Viewing default authentication mode).
To modify the authentication mode of a user, see Defining the Login of a Person.
