------------------------------------

             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.
