Azure Single Sign-On Behaviour

The behaviour of SSO is as such...

 

When user A selects NO for “Stay signed in” prompt, the password will NOT be cached but session cookie lifetime is still 24 hours.

If user A logs out the session, other user has no access to the previous session.

However, if user A doesn’t close the internet browser without logging out, another user still can access to user A’s data within 24 hours.

 

On the other hand, when user A selects YES for “Stay signed in” prompt, the password will be cached (default 90 days).

Another user from the same workstation will has access to user A session regardless whether user A closes the internet browser or completely logs out the session.

活读巧记中国朝代历史

年青時,阅读历史故事或武俠小說,时常总会把一些历史朝代混乱,张冠李戴。
后来后来,知道以下中国历史朝代的歌诀之后(i.e. China history),一下子就完全通了。


三皇五帝夏商周,
春秋战国乱悠悠,
秦汉三国西東晋,
南朝北朝是对头,
隋唐五代又十国,
宋元明清帝王休。
