I am trying to get NetWare and ASP.Net...

I am trying to get NetWare and ASP.Net working with VB.Net code behind. I have been able to get a user authenticated and for NetWare to give that user's full name. What I need to do now is check if this user is a member of a certain NetWare group. Any ideas?

Current membership code I have is:

Private Function Is_MemberOfGrp(ByVal strGrpNameToChk As String, ByVal
		strUserToChkAgainst As String) As Boolean

Dim blnAnswer As Boolean = False
Dim strErrMsg As String = ""

Try
		Dim saMembers As System.Array
		Dim dblCounter As Double = 0

'1] Find Group

objUser = objNWDir.FindEntry(strGrpNameToChk)
		Dim strUserName = objUser.GetFieldValue("Given Name", "No Value") + " " +
			objUser.GetFieldValue("SurName", "No Value")
			dblCounter = objUser.Entries.Count

'2] Get its list of members

saMembers = objUser.GetFieldValue("Member", "NotFound", True)

'3] Loop thru Member list

For dblCounter = LBound(saMembers) To UBound(saMembers)
			If (saMembers(dblCounter) = strUserToChkAgainst) Then
				blnAnswer = True
			Else
				blnAnswer = False
			End If

Next dblCounter

Catch
		strErrMsg = CStr(Err.Number) + ": " + Err.Description
	End Try

end_func:
	Is_MemberOfGrp = blnAnswer

End Function

The group object doesn't have a given name or a surname. So I'm not clear on whether you have the user and wish to read the group membership, or if you have the group and wish to read the member list.

Your question indicates you already have a user, so it's easiest to read the group membership property of the user that you have.

objUser = AxNWDir1.Entries.Item(strUser)

and once you have the user, call

saMembers = objUser.GetFieldValue("Group Membership", "NotFound", True)

so you get a list of the full names of the groups to which that the user belongs. This is easier than searching for groups and reading the members.
