--------------------------------------------
Summary: We don't need anymore a credential cache
Key: DIRSERVER-2281
URL: https://issues.apache.org/jira/browse/DIRSERVER-2281
Project: Directory ApacheDS
Issue Type: Improvement
Components: authn
Affects Versions: 2.0.0.AM25
Reporter: Emmanuel Lecharny
Fix For: 2.0.0.AM26
Once upon a time, when we were authenticating users, we were fetching the
password from the backend, which was costly, beside checking that the entry
existed (another lookup done on the backend).
The idea was to add a credential cache to avoid doing that repetitively.
The thing is that it's not anymore necessary because before doing any kind of
password verification, we fetch the entire entry, including its password.
Still, we have kept the credential cache.
We can now remove it, which will incidentally remove a contention point (and
the necessity of invalidating the cache when the entry was moved, renamed, or
its password removed or modified).
An extra benefit is that we won't have a place in memory where the password
will be stored for a long period of time...
