Help with Vacation Mail

[ahook]

Hello,

I have downloaded the vacation plugin for roundcube.  I have the default settings.  I can not get the vacation tab to appear in the roundcube interface. 

My config.ini
[default]
driver = "ftp"
subject = "Default subject"
body = "default.txt"


[dotforward]
binary = "/usr/bin/vacation"
flags = ""
message = ".vacation.msg"
database = ".vacation.db"
alias_identities = true
set_envelop_sender = false
always_keep_message = true


main.inc.php has this line:
$rcmail_config['plugins'] = array('vacation');

Note I do not have squirrelmail installed.  Also, using Sendmail.

Please advise.
