>
> org.apache.hadoop.security.LdapGroupsMapping allows specifying ldap
> connection password in a file using property key
> hadoop.security.group.mapping.ldap.bind.password.file
> The code in LdapGroupsMapping that reads the content of the password file
> does not trim the password value. This causes ldap connection failure as the
> password in the password file ends up having a trailing newline.
> Most of the text editors and echo adds a new line at the end of file.
> So, LdapGroupsMapping should trim the password read from the file.
