Hello all,

I’ve been trying to get digest authentication working for soap calls for  
two weeks now. All the examples I find seem to be flawed. Here’s the  
code that I’m using which is right out of the httpclient docs.

require ‘httpclient’  
require “soap/wsdlDriver”  
require ‘soap/rpc/driver’  
require ‘uri’

user = “admin”  
pass = “pass”  
wsdl = “[http://someserver/file.wsdl](http://someserver/file.wsdl)”

driver = SOAP::WSDLDriverFactory.new(wsdl).create\_rpc\_driver  
driver.instance\_methods  
driver.options[“protocol.http.digest\_auth”] \<\<  
[‘[http://someserver/SoapServer.php](http://someserver/SoapServer.php)’, user, pass]

info = driver.GetSystemInformation(‘’)  
puts info

I’ve changed the server url because I don’t want to expose it’s  
location.

The error I get is:  
c:/ruby/lib/ruby/1.8/soap/property.rb:269:in `check_lock': cannot add any key to locked property (TypeError) from c:/ruby/lib/ruby/1.8/soap/property.rb:192:in `local\_referent’  
from c:/ruby/lib/ruby/1.8/soap/property.rb:230:in `referent' from c:/ruby/lib/ruby/1.8/soap/property.rb:106:in `[]’  
from C:/Documents and Settings/Administrator/Desktop/mxpua.rb:19

The line numbers in mxpua.rb won’t match up, but I’m sure you guys see  
where it’s failing.

Any help with this would be great. I can’t understand how all the  
examples I find would all be wrong, but they all seem to use the same  
process to add the digest auth information to the object.

Thanks for your help.

-Ryan

Wild guess: You are using SSL where you shouldn’t, or you aren’t using  
SSL where you should?

Can’t be of more help, though.

Phillip,

SSL shouldn’t be a factor here. The service I’m trying to access is  
clear-text http. Just using digest authentication.

The error that I’m getting in Ruby looks to be that I can’t modify the  
‘driver’ object once it’s been created.

I’m guessing that there is either a way to pass those options as the  
object is getting created or there is a different syntax to modify the  
object after it’s been created, but before the SOAP call gets sent.

Thanks,  
Ryan

Are you running into this issue? I am trying to perform basic  
authentication and getting the same exception.

Hello,

I have a bit of information, if you are still working on this.

I believe this line

> > driver.options[“protocol.http.digest\_auth”]

should really be

> > driver.options[“protocol.http.auth”]

If the server accepts basic authentication, that will be used.  
If the server accepts digest authentication, that will be used.

I send authentication information to the server in both cases,  
but only the first option (basic) is accepted by the server.

I would like to know if it works for you now?

I’m collaborating with a Ruby expert tomorrow to see if we can’t find a  
fix or workaround. I’ll update this thread if we succeed.

Yup, still getting the same error.

This change suggested above didn’t help either.

I believe this line

should really be

That would be great. Let me know how it turns out.

I gave up using Ruby because of this. I wanted to move from Perl to Ruby  
for SOAP type services, but no love.
