I'm now thinking on how to implement the caching of group-name to SID mapping with configurable timeout, ideally using existing interface - ideas welcome.
The "cache" module should be able to do that. My $0.02 is to just create the mappings, and let the rest of the policies decide what to cache (or not).
The mapping I am interested at is of group-name to SID, which is relevant to *any* user and not related to what the AD-Group compare function actually does. I didn't figure yet how to use the cache module for that.
I think winbindd already caches those mappings? Is so wbcCtxLookupSid / wbcCtxLookupSids and friends should be relatively fast (i.e. no network traffic unless needed). Though it does mean another call to winbindd, which needs the connection pool. Question is whether the added complexity of managing a cache in FreeRADIUS is worth it if there's already another cache on the same box anyway. -- Matthew
