Subject [jira] [Commented] (ZOOKEEPER-1782) zookeeper.superUser is not as super as superDigest
Date Fri, 23 Jun 2017 16:51:00 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-1782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16061211#comment-16061211

Michael Han commented on ZOOKEEPER-1782:
----------------------------------------

Committed to master: fb267672d219c73c0cf2527fafebc1a0b17d3bee
branch-3.5: 822e51a01201fc56e810aacf36f828cf226c45e3

Not sure if this should be in 3.4 though - if needed, the patch needs a little rework on the
doc because it references something (x509 auth) that does not exist in br-3.4.

> The zookeeper.superUser system property does not fully grant super user privileges, like
zookeeper.DigestAuthenticationProvider.superDigest does.
> zookeeper.superUser only has as many privileges as the sasl ACLs on the znode being accessed.
 This means that if a znode only has digest ACLs zookeeper.superUser is ignored.  Or if a
znode has a single sasl ACL that only has read privileges zookeeper.superUser only has read
privileges.
> The reason for this is that SASLAuthenticationProvider implements the superUser check
in the matches method, instead of having the super user include a new Id("super","") as Digest
does.
