Security Software

Hi there,

I have been trying desperately for weeks to get Microsoft .net System.DirectoryServices.Protocals and c# to talk to a Sun Java System Directory Server.

My understanding is that the System.DirectoryServices.Protocals namespace talks directly to LDAP, bypassing the ADSI security layer that Active Directory uses and I have seen posts that suggest that this connection is possible. However, although I can create the connection to the LDAP server successfully, the second that I try to send a request through the connection, it fails with an 'DirectoryOperationException' stating that "The authentication method is not supported."

The code I am using is for a command line app that will add some new objects to the LDAP server. The usage is:
App.exe <ldapServer> <user> <pwd> <targetOU>

I am using the following command to attempt to use it against a Sun LDAP server running on the same box:
App.exe localhost admin password ou=Blah,dc=some,dc=net

And all I get is:
DirectoryOperationException:The authentication method is not supported.

Here is the code; if anyone can give me an idea of what I am doing wrong I will be eternally grateful!
