We used an http_request to communicate between the sites. The main site would return information about the user as well (something like profile data). The actual trick was that the "slave" site had to fake passwords because the main site did not pass those back (and cannot because they are encrypted). In our case, a user who was not yet authenticated was actually bounced over to the main site for
the true sign in, and then back to the site they originally entered. This required us to check if a cookie from the main site was present.<br></span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><br><span></span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><span>If you pursue something like this, you might want to consider an additional site whose only reason for being is authentication.<br></span></div><div> </div><div><font color="#ff007f" face="bookman old style, new york, times, serif" size="4"><i><b>Nancy</b></i></font> <br></div><div><font face="arial, helvetica, sans-serif">Injustice anywhere is a threat to justice everywhere. -- Dr. Martin L.

I have several Drupal sites, each one with a different purpose but
all of them made for the same organization. But I have a problem
since the same user must authenticate himself in every site..., and
that is very unconfortable. Is there any module that allows a user
puts his/her credentials in a site and then enter to another site
using the same credentials?..., in other words, is it possible put
all the sites together with the same authenticaton system (eg.
local, LDAP, etc.)? Hope you can help me..., thanks...<br> </div></div></div> </div> </blockquote></div> </div></body></html>
