Mohit Sabharwal commented on HIVE-8916: --------------------------------------- We could add documentation to [Configuration Properties -- hive.server2.authentication.ldap.Domain | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.server2.authentication.ldap.Domain] In case of LDAP authentication, {{hive.server2.authentication.ldap.Domain}}, if configured, is appended to the LDAP username passed in the client connection. This is because LDAP providers like Active Directory expect a fully qualified username that includes the domain. Starting 0.15.0 (HIVE-8916), if the username passed in the client connection already includes the domain, any value configured in {{hive.server2.authentication.ldap.Domain}} is not appended to the username. > Handle user@domain username under LDAP authentication > ----------------------------------------------------- > > Key: HIVE-8916 > URL: https://issues.apache.org/jira/browse/HIVE-8916 > Project: Hive > Issue Type: Bug > Components: Authentication > Reporter: Mohit Sabharwal > Assignee: Mohit Sabharwal > Fix For: 0.15.0 > > Attachments: HIVE-8916.2.patch, HIVE-8916.3.patch, HIVE-8916.patch > > > If LDAP is configured with multiple domains for authentication, users can be > in different domains. > Currently, LdapAuthenticationProviderImpl blindly appends the domain > configured "hive.server2.authentication.ldap.Domain" to the username, which > limits user to that domain. However, under multi-domain authentication, the > username may already include the domain (ex: u...@domain.foo.com). We should > not append a domain if one is already present. > Also, if username already includes the domain, rest of Hive and authorization > providers still expects the "short name" ("user" and not > "u...@domain.foo.com") for looking up privilege rules, etc. As such, any > domain info in the username should be stripped off. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
