I am using

WorkflowManagementServer MgmtServer = new WorkflowManagementServer ();

            // Create instance of the Permissions and ProcSetPermissions class

            Permissions permissions = new Permissions();

            ProcSetPermissions procPermissions = new ProcSetPermissions();

            // Set the required permission properties

            procPermissions.ProcSetID = 1;

            procPermissions.UserName = userName;

            procPermissions.Admin = true;

            procPermissions.Start = true;

            procPermissions.View = false;

            procPermissions.ViewPart = false;

            procPermissions.ServerEvent = false;

            // Add the ProcSetPermissions object to the Permissions object

            permissions.Add(procPermissions);

            // Multiple permissions can also be added

            // for other process sets

            ProcSetPermissions procPerms2 = new ProcSetPermissions();

            procPerms2.ProcSetID = 2;

            procPerms2.UserName = userName;

            procPerms2.Admin = true;

            procPerms2.Start = true;

            procPerms2.View = false;

            procPerms2.ViewPart = false;

            procPerms2.ServerEvent = false;

            permissions.Add(procPerms2);

            // Update the permissions

            bool updated = MgmtServer.UpdateUserPermissions(userName, permissions);

Does this UpdateUserPermissions method create user on to K2 if the user is not present ??

What rights should one need to add users on to K2 using above code???

Thanks in advance
