---------------------------------------
Summary: Ranger PamAuthentication is slow
Key: RANGER-3741
URL: https://issues.apache.org/jira/browse/RANGER-3741
Project: Ranger
Issue Type: Bug
Components: Ranger
Reporter: Pradeep Agrawal
Ranger PamAuthentication is slow, it takes 3 seconds to finish the
authentication whether its success or fail.
If PamAuthentication is enabled then even for the basic jdbc authentication the
PamAuthentication check is executed first and after the PamAuthentication
failure basic jdbc auth is attempted. this way all the basic jdbd auth request
takes 3 seconds more which slow downs the large number of subsequent request.
Ranger PamAuthentication uses
[https://mvnrepository.com/artifact/org.kohsuke/libpam4j] library which is old
and based on native c code.
I have tried with latest available version and latest jna version also but with
that also there is no improvement in the response time.
