Problem connecting to AD

I need to connect to a OU. I know it works because I got it worked before but I forgot the string

If entered this way, it works

CN=Schema,CN=Configuration,dc=DOMAIN,dc=NET

But i need to search from an OU and I tried

CN=Schema, OU=groups, CN=Configuration,dc=DOMAIN,dc=NET

but i am getting an error, any help on this is greatly appreciated

thanks

Please provide the error you get.

Also, Im not sure exactly why you are trying to connect to the schema, perhaps you can explain what you wish to accomplish?
