â‘ The user logs on to OS client 1.
â‘¡ The OS client 1 transfers the username and password to SIMATIC Logon Service after
logon.
â‘¢ The SIMATIC Logon Service transfers the user name and the password to the logon station,
to the domain controller, or to the local computer.
â‘£ The logon station, domain controller, or the local computer verifies the user name and
password and determines the group membership. This information is passed to the SIMATIC
Logon Service.
⑤ The SIMATIC Logon Service transfers the group membership and informs the OS
application if the password was correct.
⑤ The User Administrator of the OS client 1 determines the user's authorizations if the correct
password was entered.
Note
If you run SIMATIC Logon with a logon computer, this computer must be available at all times
and must not demonstrate any excessive peak loads; Using the ES as the logon computer is
not recommended for this reason.
With SIMATIC Logon you can log on via the local computer, irrespective of whether you are
working with a logon computer or a domain. We recommend that you create all the necessary
users and groups on the local computer also, so that you can still log on to applications when
the logon computer or domain are unavailable.
