[horde] horde-remove-user-data script usage

[John H. Bennett III]

Hello,

How is one supposed to use this script?  I log in to my server as root and run

php /usr/bin/horde-remove-user-data

I get the below, no matter if I try to put in a valid user or not.

[root at www Horde_Smtp]# php /usr/bin/horde-remove-user-data
[  INFO  ] Horde directory: /home/httpd/html/horde

Username: john

Application to remove data from (blank for all apps):

Are you sure you want to remove user data?
     (y) Yes
     (n) No

Type your choice [n]: y

====================

Fatal Error:
You are not allowed to remove user data.

1. Horde_Cli->fatal() /usr/bin/horde-remove-user-data:53


Thanks in advance,

John
