Greg

Dmitri Pal is advocating for generic printf-like thing as opposed to one function per event. Dmitri wants plugin to handle future events without updating module.

Simo

Because we send somewhat linearized, we wouldn't have to linearize in the plugin.

Greg

Could provide both.

Shawn

Current structure of audit is separate function wrappers. Populate event structure into audit system. XML. Dynamic generation. Revamp in progress includes libbsm, XML definitions, primitives.

Tom

Enumerated event types in libbsm will be preserved?

Shawn

Broken down to KDC, kadmin. XML ID # per service event (KDC/kadmin). More transparent info. (Yes, retain one numeric ID per event type.)

Greg

XML affects API?

Shawn

Superset of structure.

Greg

several possibilities

1. 1 function per event... plugin writer linearizes
2. call 1 generic function
3. hybrid: default implementation of function linearizes (if back end doesn't implement a specific event function)

Shawn

To support more generic approach, operator as element of event structure... string.

Greg

Can't find...

Shawn

Framework. ADT interface. Will try to find differences.

Tom

Would like to hear high level requirements about what events need to be audited.

domain_realm

Simo

Multiple masters. Trust relationships. Which KDC to contact. Trusted domains. CAnnot change domain_realm mappings on the fly. Pluggable interfaces?

Greg

Not too hard. (Right now busy with an2lname though) You can do via your custom KDB back end.

Simo

Dropping domain_realm into include file but not getting read until KDC restart.

Greg

Tough the master profile file.

Tom

We've talked about removing rechecking behavior in the future, so don't count on this as a long-term solution.

Simo

New trust with AD.

Greg

DAL can return a referral TGS principal.

Simo

Clients using domain_realm. So need plugin.

Greg recaps long-term DNS avoidance strategy.

Greg

Plugin work more likely to happen in 1.12 time frame. Short hostnames... does client append domain? Sending short names to KDC... Nico et al. say the KDC's search path might be different than the client's; need to deal somehow. Maybe get search path through res_* API.

Simo

First send user-provided name without change, then maybe append domain.

Tom

Your preference is to have config variable to turn off client hostname resolution? (This could happen for 1.12.)

Simo

Yes.
