TcUserManager (CoClass)

The TwinCAT User Manager is implemented in the class TcUserManager. TcUserManager stacks directly onto the Windows NT user administration and can therefore offer all the security features of Windows NT. An important feature of the Windows NT security system is the option of either providing or withholding privileges for each operating system object (e.g. hard disk, file, network, …). Furthermore the users, user groups and their privileges can be propagated across the network.

The default interface of TcUserManager is called ITcUserManager,  TcUserManager is implemented as "In Process Server" in the DLL "TCATUserMan.dll". For reasons of compatibility part of the functionality can also be attained through exported functions of the DLL. New applications should however use the COM interface ITcUserManager.
