>  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.
