Sun OpenSSO Enterprise 8.0 Administration Reference

Cookie Domains

The list of domains that will be returned in the cookie header when setting a cookie to the user's browser during authentication. If empty, no cookie domain will be set. In other words, the OpenSSO Enterprise session cookie will only be forwarded to the OpenSSO Enterprise itself and to no other servers in the domain.

If SSO is required with other servers in the domain, this attribute must be set with the cookie domain. If you had two interfaces in different domains on one OpenSSO Enterprise then you would need to set both cookie domains in this attribute. If a load balancer is used, the cookie domain must be that of the load balancer's domain, not the servers behind the load balancer. The default value for this field is the domain of the installed OpenSSO Enterprise.
