Vaibhav Gumashta commented on HIVE-6466:
----------------------------------------
[~xuefuz] Thanks for taking a look. PAM (pluggable authentication modules)
provides the benefit of plugging existing authentication mechanisms to Hive.
It's a fairly standard mechanism on most *nix systems. The underlying modules
(also fairly standard in *nix distributions) implement authentication, account
management, session management and password management on which multiple
applications can rely. Users of Hive can use their existing PAM setup for
security without having to rely on Kerberos. Support for PAM is also provided
in existing databases like Oracle
(http://docs.oracle.com/cd/E11857_01/em.111/e16790/security3.htm#autoId41),
MySQL (http://dev.mysql.com/doc/refman/5.5/en/pam-authentication-plugin.html),
Postgres (http://www.postgresql.org/docs/9.1/static/auth-methods.html).
I'll add more documentation and usage notes in a short while. Thanks again!
