經進一步研究,我在自述形式在此就來了:

The Domain Access module allows the creation of domains with different
hosts. However, security standards dictate that cookies can only be
read from the issuing domain.
As a result, you may configure your site as follows, but when you do so,
users cannot be logged through a single sign in.
example.com
one.example.com
myexample.com
thisexample.com
While example.com and one.example.com can share a login cookie, the
other two domains cannot read that cookie. This is an internet standard,
not a bug.
Note: See the INSTALL.txt for instructions regarding Drupal's default
cookie handling.
這絕不是一個bug像我想。我在這裏回答,以便其他人可以從我花在解決問題上的時間中學習。
