We use pubcookie for single sign on here.  After people log on the central
pubcookie login server, they can access typo3 without logging in again. 
Not clear how your single sign on system is implemented, but you may want
to get some ideas by reading the code of the Pubcookie SSO (jm_pubcookie)
extension on typo3.org.  It's simple.  Also, http://www.single-signon.com/
might be helpful.
