ebroder / auto-aklog Goto Github PK

Snow Leopard seems to have gotten rid of the login_logout_notification API that auto-aklog uses to hook credential changes, so auto-aklog basically needs to be completely re-written.

I see a few options for notifications that come from the CCacheServer when the credential cache collection gets updated, both in KerberosFramework/Kerberos5/Sources/ccapi/server/mac/ccs_os_notify.c:

1. notify_post. CCacheServer uses notify_post(3) to send a "com.apple.Kerberos.cache.changed" message through the OS X notifyd whenever the credential cache collection changes.
2. NSDistributedNotificationCenter. CCacheServer sends one of two messages through the distributed notification center when either a ccache or the ccache collection changes.

Unfortunately, I can't find a way to actually spawn a process (or call a particular piece of code) in response to either a notifyd message or a distributed notification, so auto-aklog may need to be come a background daemon that blocks on receiving one of those two notifications.
