How to make global keychain in Mac OS X Lion I need to create a keychain that can be used by any user. 

When I check a keychain as shared in Keychain Acess->Edit->Keychain List, it just disappears and I can't see this keychain in the list anymore.

What's the problem? Thanks.
Create the new keychain in

/Library/Keychains/

like the System.keychain, this way any user can access the keychain.
