Load balancing

The Manager web application provides simple load balancing in order to distribute user sessions and the resulting load across multiple processes or even servers. To do this, the application is installed multiple times on the same or on other servers.

All collaborating applications that can be logged into, are declared in the applications' Application pool. The selection algorithm for load distribution distributes user logins across the defined applications.

NOTE: Even if only one application is installed, it must be defined in your application pool, otherwise you cannot log in.

Table 59: Supported algorithms for load balancing
Algorithm Description


This algorithm distributes user logins such that each application in one language has the same number of active users, if possible. This algorithm is the default and is required in 99% of cases.


This algorithm distributes user logins by order of application definition in the application pool. First of all, all user logins are forwarded to the first application in the desired language. When this has reached it maximum load, logins are forwarded to the next application.

Load balancing solves the following problems:

  • Multi-language

    Language is fixed for per application so that an application can only provide user sessions in one language. If users can log in with multiple languages, at least one application must be installed for each language.

  • Bypassing resource limitations

    If multiple web applications are installed and these are assigned to different Internet Information Services application pools, these are started in separate processes.

  • Increasing performance

    Performance can be noticeably improved by installing on several servers.

  • Redundancy

    Multiple installation does not necessary complete outage if just one of the installed application fails.

Single sign-on

The Manager web application supports a single sign-on mechanism that enables authentication of a user without the user having to repeatedly enter their user name and password.

Prerequisites required:

  • Anonymous access disabled.

  • Configuration of an authentication module capable of single sign-on.

    For detailed information about the One Identity Manager authentication modules, see the One Identity Manager Authorization and Authentication Guide.

  • Permissions in the application’s own application pool

You can disable anonymous access on the web server. This means the user's browser must provide the data required for authentication.

To disable the anonymous access

  1. open the configuration of the Manager web application in the Internet Information Services and activate the configuration for Authentication.
  2. Change the value of the status to disabled in Anonymous Authentication.
