LDAP://CN=username,OU=subdirectory,OU=parentdirectory,DC=mydomain,DC=org

LDAP://mydomain.org/CN=username,OU=subdirectory,OU=parentdirectory,DC=mydomain,DC=org

What is the difference between the 2? and why do we write the mydomain.org next to the ldap://, in the second connection string?

Thanks

The only times you really need to specify this is when you are doing things from either a non-domain security context or from another domain.  If you are in the same domain and with a domain security context, then serverless binding (DN alone) is a good choice.  What can occasionally bite you is unrecognized custom schema from one domain to another needs the netbios or FQDN domain name in the server position - what happens is that the trusted domain does not know where to go to download the abstract schema, so it uses its own and hence the custom schema is missing.  Admittedly, this is a bit of an edge case, but I have seen it a time or two.  More common, if you are running the code as a different domain account or a local account, the process does not know how to find that domain from the DN alone - so the server or domain name is helpful to help it resolve it.

Edit:  I should mention that it is sorta-kinda a serverless bind when you put the domain name there instead of a server, but it does not use the exact same mechanisms, so we don't call it a serverless bind (even though there is no server there).
