Ben,
Not easily. The problem here is if you set a cookie on Site B, it won't
be sent to site A.
Was it you that asked this the other day, it is a solveable problem,
what capabilities do both servers have, do they have php, does only
one, which one, does one/both have a database, session support?

so let me get this straight,
if someone tried to access a directory of A (not the whole of site A,
just a page) and were not logged on at siteB, then they are redirected
there, then on successful login they are redirected back to site A, to
the page they were on, and now site A asks them to log on as well.
user goes to A, site A checks whether it lets the user through, if not
there it makes the ACTION of the form point to an iframe in the page
and to a script on siteB, and uses RSA for the form, with B's public
key in javascript, as well as a ID from siteA which is set in siteA's
cookie, user logs in, this form is encrypted and posted to siteB, site
B decrypts using it's private key, accepts if user gets it right and
makes a cURL session to a script on siteA, sending it the ID, which A
stores in database, id->"redirect=no" then it sends back javascript,
parent.location.reload(), to force the page on siteA to reload, now
site A checks whether user with this session needs to be refreshed,
and id is ok, sent from B, so A prints the login form for A with
ACTION pointing to a script on A, or just shows A's data.
Who said anything about all this crap?
From what I understand what the user wants, if someone is signed into
site A, they can access anything on Site B.
thats not what the OP said
I suspect the entire idea is to not have to sign into both sites.
clarification was needed (its why I asked)since thats not what the OP
said
If they try to access a page at Site B but don't have the authority,
they are redirected to Site A for sign in. Once signing in, they can
access the page on Site B.
If someone try to access site "A" directory, I want it redirected to
site
"B" for login. After login at site "B", you see the link to site"A".
When
you click it, you see login page for site "A".
it reminds me of stealing credentials - using xss, dont know whats on
the OPs mind really,
it can be done without encryption, sure - I was having fun, lets see
what the users problem actually is
As for the rest - what a complicated way of handling things.

hardly! just form, some js, and a couple of scripts! not quantum
physics this stuff!
overcomplicated sure, this isnt a hard problem, but whats wrong with
having a little fun, just a quick server-server connection, together
with sessions, but the method used above will work whatever the user
wants

And among other things, requires JS.
But yes, I consider it quite complicated - lots of things which can go
wrong!

session stuff is standard and trusted, db the same, form posting the
same, as for requiring js, thats just to keep things secure, dont /
have/ to. The only extra step over and above any other method is the
rsa, standard implementation once again, reliable and fast, the
problems as usual would be on the wire, which we are all used coding
for.
Still needlessly complicated. Won't work for the estimated 10-15% that
have JS disabled, and all kinds of possibilities for other
communications between the two systems to fail.

A kludge just waiting to break. Much easier would be for the two to
have a shared database.

Alternatively, a one-time hash can be used - for instance, take a number
which increments every time, or the current date and a sequential
number. Embed the number in a predefined string and take the MD5 hash
of the resulting string. On the receiving end, validate the hash (same
algorithm) and start the session. Each has can only be used once.

Or any of a number of ways much simpler than yours.

(Top posting fixed)

Which is it - do you need js or don't you? As for whether you need it or not - you have control over the server and PHP implementation. You have *no* control over the client and what they have installed.

So you can always guarantee crypt() and other php function work - but you can never guarantee anything related to js works.

As I said - yours takes a lot of programming and is needlessly complicated. There are many simpler ways, of which I indicated two.
