I was referring to this code:
// This is of the form: TEAMID.mSSO
#define kmSSOKeychainGroup @"3Q4M6DQ9WM.mSSO"

which is used here:
[keychainSearch setObject:kmSSOKeychainGroup forKey:(id)kSecAttrAccessGroup];   // inform the search that we're using the shared keychain

The use case I was talking about: I want to create a static library with the keychain stuff for two customers with team ids: TEAMID1 and TEAMID2.

I would have to somehow read the appropriate TEAMID from within the app which contains the static library. One option could be to have the customer define the TEAMID in a .plist file or something. But, it would be nice if I could just read the TEAMID during runtime.
