I have a connection string for LDAP protocol
which works fine.
But I need to use a LDAPS connection :
which does show up in ldp.exe windows form when I test the connection.
Unfotunately it does not work in the Asp.Net application. I get "Unknown error (0x80005000)".
I am not sure whether LDAPS string is even possible with Asp.Net. I downloaded the source code into LDAPConnection.cs class and was unable to find any valuable information.
The method you found that works is indeed using LDAPS:
That's the only way to do it. I do that in one of my existing projects. It doesn't understand "LDAPS://".
If you don't believe me :) fire up Wireshark as you debug. When it connects, you'll see the SSL handshake to your domain controller.
Port 636 is only for LDAPS. Port 389 is the non-SSL port.
If you have more than one domain, you can use port 3269 for the global catalog via SSL.
