--------------------------------------
Summary: Allow specifying LoginContext directly
Key: ZOOKEEPER-4938
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4938
Project: ZooKeeper
Issue Type: New Feature
Components: kerberos
Reporter: Istvan Toth
Currently ZK allows setting the Application name, but always uses the global
javax.security.auth.login.Configuration object to retirieve it.
Some applications (notably anything using the Hadoop UserGroupInformation)
create and set their own LoginContext object.
For these cases, the user somehow needs to duplicate the required jaas
Configuration, and install it globally (either creating a _jaas.conf_ file and
setting the_java.security.auth.login.config_ system property, or by
programmatically installing a Configuration object)
Life would be MUCH easier if ZK allowed directly setting the LoginContext
object for, so that applications can set the SASLconfig without having to
override the global Configuration.
