Review request for KDE Frameworks and Dawit Alemayehu.


Changes
-------

Addressed David's comments.


Repository: kio


Description
-------

When authenticating agains a server offering multiple authentication methods make sure to attempt other methods in case the best one fails.
    
This also fixes a connection close issue in the middle of an NTLM authentication dialog due to clearing the password.

Testing
-------

I have performed testing on an IIS 7.5 server which offered 3 authentication options: Negotiate, NTLM and Basic. Since I have Kerberos configured the original code would only try Negotiate and because it failed it would retry it endlessly. With this patch authentication correctly falls back to NTLM or Basic (if NTLM fails too).


Thanks,

Krzysztof Nowicki
