HPSM: SOAP Fault occurred: A CXmlApiException was raised in native code : error 3 : login(3)

Hello everyone, I'm new here,

I'm trying to connect to HPSM but this message appears:

Authentication failed. Contact your system administrator for assistance. 

SOAP Fault occurred: A CXmlApiException was raised in native code : error 3 : login(3): Invalid login name/password. Please try again.

Any ideas? How can i solve it? Thanks in advance
