Patch Set 2:

I thought that this would be similar to the "closed" from osmo-nitb where each subscriber needs authorized=1 in the hlr in order to be authenticated. I thought that the ACL would be like the authorized flag.

closed:
MCC/MNC of the IMSI matches home-network ==> Authenticated!
IMSI in ACL ==> Authenticated!

acl-only:
IMSI in ACL ==> Authenticated, otherwise, REJECTED

The SGSN manual seems not to document how the ACL exactly works. Anyway, I think I got it now. I will abandon the patch.
