[jira] [Comment Edited] (HIVE-13590) Kerberized HS2 with LDAP auth
enabled fails in multi-domain LDAP case
[ https://issues.apache.org/jira/browse/HIVE-13590?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15665704#comment-15665704 ]

---------------------------------------------------------------
[~Tagar] as I recall, we did not use the KerberosName.getShortName for LDAP users for two reasons:
1. security: add the rules to LDAP users in Hadoop auth_to_local might introduce the security holes to other components accessing Hadoop only via Kerberos.
2. backward compatibility: for HS2 only using LDAP authentication. The KerberosName/auth_to_local rules were previously not required.
HTH, thanks

> In a kerberized HS2 with LDAP authentication enabled, LDAP user usually logs in using username in form of username@domain in LDAP multi-domain case. But it fails if the domain was not in the Hadoop auth_to_local mapping rule, the error is as following:
> {code}
> Caused by: org.apache.hadoop.security.authentication.util.KerberosName$NoMatchingRule: No rules applied to ctang@mydomain.com
> at org.apache.hadoop.security.authentication.util.KerberosName.getShortName(KerberosName.java:389)
> at org.apache.hadoop.security.User.<init>(User.java:48)
> {code}
