Hi,
I have two E-Blah boards that point to the same member directory.  They are completely separate websites (with different domain names) but the idea is that members of one can log into the other.

This works, but when you link from one board to the other it still requires you to log in again.  I'd like to make this seamless so that if you are already logged into one board, the other automatically recognizes you.  

I am not using sessions (although I could) and I already tried setting the cookie prefix to the same name on both boards.

Any ideas?

Thanks!

This is probably possible, it would depend on the link to your Members and Prefs folder though.

Hey Martin,
What do you mean?  Both boards have the same members directory (in Settings.pl, they both point to the same directory) but different prefs directories.

Keep in mind that you can already log into both boards with the same username and password.  What I want to do is make it so that if you are logged into one and then point your browser to the other, you are automatically logged in (rather than typing your username and password in again for the second board).

Thanks!

Again, this should work if you are Cookies only, if you have sessions running then it won't work as sessions are stored in the Prefs folder.

no such luck. i am not using sessions on either site - only cookies.  i think the problem has to do with the fact that a browser will only send cookies to example1.com if they were originally set by example1.com.  example1.com can't retrieve a cookie set by example2.com (think about it, that would be a huge security breach).  sessions ID's are also stored in cookies so this would have the same problem.  

if someone has come up with a workaround to this, even just conceptually, that would be great

You could host both forums on the same site, I have a friend who has three websites catering different subjects but he hosts all 3 forums on the one site.

yea that would work, but unfortunately not an option in this case - it would require alot of work and each board has its own core group that like to own thier separate hostnames.  My example was simplistic, there are actually quite a few boards involved...

hi - i know this is an old thread but i never got it working so i'd like to revive it.  basically i have 4 websites with separate URLS that all have eblah.  i'd like to get it to work so that if you have logged in to one of them, you are automatically logged into the other.  i am using cookies only (no session ID) and the cookie prefix is the same.  unfortunately i think cookies are tied to the URL.

does anyone have any ideas?
thanks!

Me, hephnet and battlemage had a discussion about cookies for multiple domains and we concluded it's not safe, wise or eve possible in some cases. search for that thread. can't remember it's name.  

thanks - i will search for it.  i didnt think its possible (at least not wihtout some serious hackups) because of the way browsers look for cookies.  my best bet now is to combine them into an umbrella url with subdirectories for each one - that should work and still keep the boards completely separate.  just not sure how the users will take to it

It's possible if you use the same domain as you can use one cookie for multiple subdomains.
