I have code (VB.NET, .Net 2.0) that authenticates to Novell Edirectory
over LDAP (below). I need to change it to work over SSL, but I can't
get it to work.

Dim dn As String = "cn=" & username & ",ou=users,o=org"
Dim path As String = "LDAP://sub.domain.com"
Dim entry As DirectoryEntry = New DirectoryEntry(path, dn,
pwd, AuthenticationTypes.FastBind)

I have tried changing the AuthenticationType to SecureSocketsLayer
(which is suggested in this article http://www.codeproject.com/KB/system/arbauthentication.aspx),
but that gives the error: "The server is not operational". I can see
from the netstat that it is using ldaps....
TCP r2d2:1295 sub.domain.com:ldaps TIME_WAIT
TCP r2d2:1297 sub.domain.com:ldaps TIME_WAIT

Another potential issue is that it is a self signed certificate, not
one from a trusted CA. From this thread I suspect that may be the
issue.

I am using the code below to add a value to users' "employeeType" attribute,
but the "UserObject.SetInfo()" line always produces the error "A first chance
exception of type 'System.Runtime.InteropServices.COMException' occurred in
app.exe".

Can anyone tell me where I've went wrong?

Thanks,
Iain

Dim UserObject As ActiveDs.IADs
Dim strBuffer As String

Try
UserObject = GetObject(strDN)
strBuffer = ""
UserObject.Put(strBand, "employeeType")
UserObject.SetInfo()
Catch
Msgbox "Error!"
Finally
UserObject = Nothing

End Try
