Domain names must have at least one "dot" or period. This
is an internet standard. See RFC 2109.
- Domain names cannot contain underscore,
"_", characters. This did not create a problem with earlier versions of
Internet Explorer (IE) or Netscape. But IE browser versions 5.5 and 6.0 do
not accept underscores in the cookie. This is an internet standard. See
RFC 1123 & RFC 932.
- Do not use the server name(such
as machinename.ibm.com or hostname.ibm.com) in the domain
name.
Examples of valid domain names are ibm.com, tx.gov,
austin.ibm.com.
Examples of invalid domain names are ibmus, state_tx.gov
- Some customers have experienced a problem with IE, in that
IE 5 and IE 6 do not seem to accept the LTPA token when the domain defined
in the SSO domain field is less than 5 characters excluding the period,
such as "cn.ca".
