The epn.conf configuration file is used to set the options
    for the ipa-epn tool to notify users of upcoming password expiration.
The configuration options are not case sensitive. The values may
    be case sensitive, depending on the option.
Blank lines are ignored. Lines beginning with # are comments and
    are ignored.
Valid lines consist of an option name, an equals sign and a value.
    Spaces surrounding equals sign are ignored. An option terminates at the end
    of a line.
Values should not be quoted, the quotes will not be stripped.
 # Wrong - don't include quotes

   verbose = True
