Single sign on

[Greer, Benjamin, CON, OASD(HA)/TMA]

Hello,
I am a first time poster to the group and I was hoping to find information
on single sign on. More specifically anyones favorite websites on the
technology and its dependancies. I need information on S3's relation with
either 
1. ticketing
2. caching
I believe these two are still the only mechanisms for S3 if I am incorrect
please enlighten me

Thanks in advance
