Perkhaps you should uninstal any existing web share rpm(s) first.
Get these
devinfo-mitel-webshare-0.0.1-3.noarch.rpm
perl-Apache-Htpasswd-1.3-10.i386.rpm
from here
http://mirror.contribs.org/smeserver/contribs/dmay/mitel/contrib/webshare/and instal them both, see the instal.sh script.
This adds a Web Shares panel under the Collaboration section in server manager.
Create new web share folders and user names and passwords using the Web Shares panel in server manager, command line mods are NOT necessary and you will possibly break security doing so.
If you create a web share called sharedstuff, then access it using
https://www.mydomain.com/webshare/sharedstuffNote the https (NOT http) this gives the secure access, you must create at least one user name and password for each web share folder (using the web shares panel).
When you access the web share you will be asked for a login name and password.
When logged in, it is fairly obvious how to download and upload files, just click on the option required and select files by browsing.
Hope this explains it clearly enough.
