Soap Login

I’m testing with SoapUI on the soap api and use my username and password as instucted;

soapenv:Body
<sug:login soapenv:encodingStyle=“http://schemas.xmlsoap.org/soap/encoding/”>
<user_auth xsi:type=“sug:user_auth”>

<user_name xsi:type=“xsd:string”>admin</user_name>
password (password here is hidden)
</user_auth>
<application_name xsi:type=“xsd:string”>?</application_name>
<name_value_list xsi:type=“sug:name_value_list” soapenc:arrayType=“sug:name_value[]”/>
</sug:login>
</soapenv:Body>

But keep getting back that login failed;

ENC=“http://schemas.xmlsoap.org/soap/encoding/”>
SOAP-ENV:Body
SOAP-ENV:Fault
10

Invalid Login
Login attempt failed please check the username and password
</SOAP-ENV:Fault>
</SOAP-ENV:Body>

What am I missing or what could be wrong?

Please help
