+[[auth-pol]]
+=== Authorization Policy
+
+Authorization determines whether a particular subscriber can access
+your network or not.
+
+The following 4 authorization policy options are available:
+
+`accept-all`: All IMSIs will be accepted.
+
+`acl-only`: Accept only IMSIs, which are explicitly white-listed
+by the Access Control List (ACL), and the rest will be rejected.
+
+`closed`: Accept only home network subscribers.
+The combination of MCC and MNC fully identifies subscriber's.
+Home network. The ACL is also heeded.
+
+`remote`: GSUP protocol is uesed to remotely access a HLR.
+Only remote subscription data will be used.
+
+
+.Example: Assign or change authorization policy:
+----
+OsmoSGSN> enable
+OsmoSGSN# configure terminal
+OsmoSGSN(config)# sgsn
+OsmoSGSN(config-sgsn)# auth-policy acl-only <1>
+OsmoSGSN(config-sgsn)# write <2>
+Configuration saved to sgsn.cfg
+OsmoSGSN(config-sgsn)# exit
+OsmoSGSN(config)# exit
+OsmoSGSN# disable
+OsmoSGSN>
+----
+<1> 'acl-only' is selected as authorization policy
+<2> Saves current changes to cofiguration to make this policy
+persistent

The GPRS Mobility Management implementation is quite simplistic at this
point. It supports the GPRS ATTACH and GPRS ROUTING AREA UPDATE
procedures, as well as GPRS ATTACH and GPRS DETACH.
