The combined settings of the SECURITY parameters in the UBBCONFIG and the DMCONFIG files have the following effects:

• When the DM_LOCAL_DOMAINS security parameter is set to NONE or APP_PW, no action is taken by the Gateway with regard to security.
• However, when the UBBCONFIG file security parameter is set to APP_PW, the application password is validated by an AUTHSVC when clients join the application. The AUTHSVC is provided by the user application.

If security is to be enforced by both the local domain and the host system for each request inbound from the host system to the local domain, the following settings must be made:

• The UBBCONFIG file SECURITY parameter must be set to one of USER_AUTH, ACL, or MANDATORY_ACL.
• The DMCONFIG file DM_LOCAL_DOMAINS section SECURITY parameter must be set to DM_USER_PW.
• The DMCONFIG file DM_SNALINKS SECURITY parameter must be set to IDENTIFY.
• The SNA stack must be configured with the appropriate parameter for IDENTIFY.
