------------------------------------
Summary: [branch-2] Upper/Lower case conversion support for group
names in LdapGroupsMapping
Key: HADOOP-15266
URL: https://issues.apache.org/jira/browse/HADOOP-15266
Project: Hadoop Common
Issue Type: Improvement
Reporter: Nanda kumar
Assignee: Nanda kumar
Fix For: 3.1.0
On most LDAP servers the user and group names are case-insensitive. When we use
{{JniBasedUnixGroupsMappingWithFallback}} and have {{SSSD}} in place, it is
possible to configure {{SSSD}} to force the group names to be returned in
lowercase. If we use {{LdapGroupsMapping}}, we don't have any such option.
This jira proposes to introduce a new {{hadoop.security.group.mapping}}
implementation based on LdapGroupsMapping which supports force lower/upper case
group names.
