Very vanilla.

Querying ldap, for subjects (in grouper) and for member identifiers
(in ldappcng), probably takes the most time.

I need to implement caching in ldappcng, probably by implementing the
TTL-based <ResultCache /> in the spml data connector similarly to the
ldap and rdbms data connectors.

However, ldap lookups are likely doubled if you are using the ldap or
jndi source adapters. So, a single caching ldap instance which is both
a source adapter and spml target would probably help the most.

I can attempt a single class which implements a grouper source adapter
and an ldappcng target.

Comments ?
