Using Sharepoint Web Services in a delphi application.

I am trying to add users and affect group memberships with a delphi application.  I can currently get the xml results from any function that does not require input, but if i try to add a user or list users from within a group, such as the GetUserCollectionFromGroup function, i get a SOAP Error, though i do not get any detailed error messages.  I am pretty sure that this is a input format issue as i cannot get back from a simple group name, while i can get a list of users from the entire site.

attached first is the code from the import of the WSDL of the UserGroup Web Service, then (Starting on line 191) the code from my test application to pull a list of users in the group 'AWP Members'

Sharepoint uses Windows Authentication by default and all web services honor the security model set within it.  So, assuming Delphi is running on a Windows system, what ever domain account the Delphi application is running as will be the account used to access Sharepoint.

I'd recommend you use this tool to analyze and play with the web services: http://www.codeplex.com/WebserviceStudio  That way you can determine what the error is and if you are passing the write data and parameters.

I am passing authentication through the HTTPRIO object.  This is a sharepoint site hosted over the internet using NTLM.  I can get responses back of lists of groups and users for the site and web as i do not have to pass data in to the web service.  So i know my issue is in passing the data to the web service, but can not figure out what is wrong.

If you are 100% sure it's not a permissions problem then use the tool I recommended to make sure you are using the web service correctly.

Ive been looking at the toold, and this is scary, its changing group memberships withoiut me ever giving credentials to login to the site.  However, I am passing the same values from my delphi applicaiton in the HTTPRIO object, but i get a SOAP error.

First off, if your personal account has 'Farm Admin' or 'Site Collection' privileges then yes when you run the tool it will relay your credentials and you might actually have those permissions.  If you want to test thoroughly create a domain test account that doesn't have the permissions and try the same tool.  You might get a completely different result.

As I said, that might be the issue with the Delphi application.  SOAP errors are very generic and can hide permission issues.

My local user here has NOTHING to do with this sharepoint site.  This site is hosted elsewhere.

again i can get results back for methods that do not require input, such as getusercollectionfromsite.  If i dont put credentials in my HTTPRIO object, i get a promt, but still get correct data back, if i do put the credentials in the object, it bypasses the prompt.

You have no control of the Sharepoint site?  That is a problem because you are at the mercy of how they have it configured.  So you don't have any access to the logs or settings for the Sharepoint site?
