WCF: Using basicHTTP user/pass authentication?

Hi.

I have to implement an Java Axis2 web service client in .NET WCF as well a
web service to witch a Java Axis2 client will connect.

I would like to provide user identification using basicHTTP user/pass
authentication. Later I'll move both ends to SSL (https).

I already implemented the Java Axis2 end:
- Axis2 Client axis2.xml:
----
....
<module ref="rampart" />
<parameter name="OutflowSecurity">
<action>
<items>UsernameToken</items>
<user>bob</user>

<passwordCallbackClass>my.package.PWCallback</passwordCallbackClass>
</action>
</parameter>
....
----

- Axis2 Web Service service.xml:
----
....
<module ref="rampart" />
<parameter name="InflowSecurity">
<action>
<items>UsernameToken</items>

<passwordCallbackClass>si.around.fri.pis.PWCallback</passwordCallbackClass>
</action>
</parameter>
....
----


I already read the MSDN docs
(http://msdn.microsoft.com/en-us/library/ms734769.aspx and others); however,
I feel a bit lost in all the buzzwords appearing there.
Can someone point me to the correct reference or even better give a relevant
web.config snap?

BTW: Will I have to use Windows built in users? Is it possible using my own
users database?

Thanks,
