[Mantisbt-soap-dev] Error 403 in Eclipse Mylyn Plugin

[Andrea V. <and...@gm...>]

I got a 403 when i try to load the projects in the eclips mylyn plugin? i
tried to use soapUI with the same credential and i receive all the listed
projects..
eclips says: Unable to load projects : Failed getting projects :
(403)Forbidden .
with this details: Failed updating the repository attributes.
java.lang.reflect.InvocationTargetException
i don't understand if this error is a kind of htaccess problem or a failed
attempt to login

this is an installation on a remote host with a full working mantis web
interface, i've tried to install mantis in localhost and connect from
eclipse and it works perfectly, i've also tried to connect to the mantis
bugReport http://www.mantisbt.org/bugs and it works too

the strange thing is that when i configure the repository and i validate
the setting it says: success! but i still can't list the projects..
