One of the easiest solutions I've used is a custom rolled SSO module.<br>
<br>
In short, each subsite has an SSO 'entry point' which has a URL
something like:<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.example.com/sso/3def4hhsgw3503==">http://www.example.com/sso/3def4hhsgw3503==</a><br>
<br>
The second argument in the URL is the user's email address after being
encrypted via 3DES then base64_encode()'ed for URL friendliness. When
that URL is accessed, the user email is decrypted and checked against
existing accounts. If there is no matching account, the user details
are fetched from the master site with the services module, the account
is created on the subsite, and the user is logged in. If a matching
account *is* found, then the user is logged in on the subsite with
user_external_login().<br>
