Soap invocation doen'st work

[fedepia]

Hello people. I'm really frustrated then to search why sugar soap doesn't work.

I have a sugar 5.0.0d and I'm trying to do a login using soap, but when a call the login web service it doesn't retrieve anything (I don't know why). So, I have installed another sugar in another directory and when I test my app with this new sugar all works well.

What could be the problem that one sugar doesn't work and the other works well?

It's really important for me because that the sugar that doesn't work, is my production sugar

Please, if anybody can help me I'll really apreciate this

Thanks a lot

FYI: I've noticied when I did a var_dump of sugar soap client the endpoint is different from the actionpoint:
[login] => Array
(
[name] => login
[binding] => sugarsoapBinding
[endpoint] => http://crm.mysite.com/soap.php
[soapAction] => http://crm.mysite.com/sugartest/soap.php/login
