"Error Contacting User Manager ... System.Exception: Security Error 1" when launching Controller, caused by firewall between Primary/Secondary servers



User launches Controller client. User chooses the database. User then authenticates with their username/password. An error appears.


Error Contacting User Manager.

System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: Security Error 1

There are many different causes of similar "Security Error 1 ... ValidateNativeUser" errors
  • TIP: For more examples, see separate IBM Technote #6204010.
This Technote specifically relates to the scenario where the cause is that there is a firewall (between primary & secondary servers) blocking communication from the 'secondary' server to the "IBM Cognos Controller User Manager" service (running on the 'primary' server).
  • This stops any users (who are trying to connect to the 'secondary' server) from being authenticated successfully by Controller.


Customer has two Controller application servers, running in a primary/secondary configuration (using the ccrRemoteServer parameter).

Resolving The Problem

Disable the firewall between the 'primary' and 'secondary' Controller application servers.
