经过进一步研究,我在自述文件中发现了这一点:
1.4.1 登录多个域
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.
这不是我想象的错误。我在这里回答它,以便其他人可以从我尝试解决它所花费的时间中学习。
