Default cookie domain

The default cookie domain value is the network domain of the computer you are installing the server on. The default cookie domain specifies the most restrictive access. This value is used to control cookie visibility between servers within the domain.

By removing domain elements (lowest sub-domain first), the cookie becomes visible to servers outside of the BMC Atrium Single Sign-On domain. For example, changing the domain remedy.company.com to company.com gives all of the servers within the company.com domain access to authentication data stored as cookies in a user's browser. The danger of increasing the cookie visibility is illustrated when the value is changed to com, giving all servers in the internet com domain access to the cookie.

Note

You cannot use sibling domains or cross-domains with BMC Atrium Single Sign-On. For example, installing the BMC Atrium Single Sign-On server in the remedy.com domain and the AR System server in the bmc.com domain is not supported. You must move user facing BMC Atrium Single Sign-On servers, load balancers, and applications into the same domain.
