With the Dws Web Service, you are able to retrieve doc-level permissions via
the Dws.GetDwsMetaData method.
With the Permissions Web Service, you are able to retrieve site and list
permissions via the Permissions.GetPermissionCollection method.

However, there doesn't seem to be any suitable Web Service for retrieving
permissions of a doc folder? Or am I missing something?

Any help/pointers will be most appreciated! Thanks.

Is there really no way to retrieve folder permissions via WSS 3.0 web services?

Hello,

recently I had similar problem - I had to query user permissions on all
folders and documents in a document library.


After long search, I found one web service method: SiteData.GetContent()
It is not very much documented, and had no examples, but after some
experimenting with the parameters, I get it to return data, which looks like
this:

<Folder>
<xml ...
...
<scopes>
<scope id='{d5475b4a-e74d-47df-87f9-00fd871a1fe5}' >
<permission memberid='1' mask='9223372036854775807' />
<permission memberid='2' mask='9223372036854775807' />
.....
</scopes>

<rs:data ItemCount="19">
<z:row ows_ID='12' ....
ows_ScopeId='12;#{D5475B4A-E74D-47DF-87F9-00FD871A1FE5}'
ows_FileRef='12;#ab1/archive.zip' ows_DocIcon='zip' ....


Basically, it returns a list of 'permission' scopes and then a list of all
documents and folders contained in the library, and for each item there is
the 'permission' scope id, which contains the effective permissions for the
item.


To get this information, i call SiteData.GetContent()
with the following parameters:

string temp = "";
string contentResult = sd.GetContent(SiteData.ObjectType.Folder,
listID, "", "", true, true, ref temp);

where listID is the document library GUID, previously retrieved by a call to
Lists.GetList(document library name)


Hope this helps,

Jogy

Thanks Jogy,

It must have been quite a substantial amount of trial and error to stumble
upon this, kudos to you...

Now next question, how do we interprete the mask values?

Btw, is there any official word on this technique? Documentation on
GetContent is sorely lacking, perhaps there's a cleaner and easier way to
retrieve folder permissions?

I think the values are same as the ones defined in SPBasePermissions

No official information, the documentation at
http://msdn.microsoft.com/en-us/library/ms772581.aspx
still states only that
"GetContent operation is polymorphic; it can be used (when called with
proper parameters) instead of specific traversal operations - GetSite,
GetWeb, EnumerateFolder, GetListCollection, GetList, GetListItems,
GetAttachments. GetContent fully covers specific traversal operations
functionality, albeit details of input parameters and syntax of the response
might differ."

Yeap, saw that doc from msdn too - wonder if there's anyone here from the MS
SharePoint team that can shed some light on the various "proper parameters"
to achieve useful results.

Meanwhile, thanks for the pointer on the permission masks.

With regards to the suggested GetContent method, it doesn't quite work out
as expected for me. It only retrieves info from immediate child folders -
i.e. it does not recurse down to deeper subfolders. Also, lastItemIdOnPage
returned is "", so I believe it's not a matter of making additional calls to
retrieve additional pages of info.
