I am not sure on how to access this through the membership provider api, but can offer up an xslt extension that will provide a series of member calls.

Some of these are good, others are not so good. Pardon the use of string builder rather than building the xml document directly - something I wrote a long time ago.

GetMembersByGroupName
GetMembersByGroupId
GetMembersAll
GetMemberGroupsAll
GetMemberGroupsForMember

thanx! i was soooo in need of this!

Thanks Casey !

Once again I was stuck when I tried to parse the xml-data, but I figured it out, here's how I got info of the groups:

[code]

[/code]

(First compile the .cs to a class library and save the .dll to the bin-directory and add the extension in the xsltExtensions.config, more about that : http://umbraco.tv/documentation/books/multilingual-11-sites/5)-use-the-dictionary-with-an-xslt-extension)

is working on a reply...
