]
Wei-Chiu Chuang updated HADOOP-12793:
-------------------------------------
Description:
LdapGroupsMapping has lots of configurable properties and is thus fairly
complex in nature. _HDFS Permissions Guide_ has a minimal introduction to
LdapGroupsMapping, with reference to "More information on configuring the group
mapping service is available in the Javadocs."
However, its Javadoc provides no information about how to configure it.
Core-default.xml has descriptions for each property, but still lacks a
comprehensive tutorial. Without a tutorial/guide, these configurable properties
would be buried under the sea of properties.
Both Cloudera and HortonWorks has some information regarding LDAP group mapping:
http://www.cloudera.com/documentation/enterprise/latest/topics/cm_sg_ldap_grp_mappings.html
http://hortonworks.com/blog/hadoop-groupmapping-ldap-integration/
But neither cover all configurable features, such as using SSL with LDAP, and
POSIX group semantics.
