The following conditions are checked when a user attempts to log in to MES Web Portal:

  1. The user’s AD username and password are checked by the web browser.

  2. The MES Security Mode must be either OS Group or OS User. If it is MES Native mode, the login will fail.

  3. The user’s AD user group or user account, depending on whether the MES Security Mode is set to OS Group or OS User, must be mapped to an MES user group or user account in the MES database. One or more of the user’s AD user groups can be mapped to MES groups.

  4. If OS User mode is being used, the user’s AD user account must map to an MES user account in the MES database.

    If OS Group mode is being used and the AD user group maps to at least one MES user group, an MES user account for the user is automatically added to the MES database.

  5. The MES user account must be active. (MES Client includes an Inactive check box option to allow a user account to be made inactive.)

  6. The user has to be a member of at least one MES user group that has at least one privilege setting assigned to it.

    • If no privileges are assigned to any of the MES user groups to which the user belongs, a message indicating insufficient privileges to use the application appears. The only available tasks that the user can perform are accessing the online help and logging out.

    • If at least one privilege for one of the MES user groups to which the user belongs is set, then even if that privilege is not related to MES Web Portal functionality, the user will be able to access the MES Web Portal application. However, only the Work Orders tile will be shown in the home page and only the Work Order option will appear in the navigation menu.

  7. MES licensing is checked. If the appropriate licensing is not available, a licensing message appears and the user will not have access to the application.

  8. Once logged in, the user will see the MES Web Portal pages and functionality as defined by their MES user groups’ privilege and access settings.
