ADSync - wrong certifier selected

I’m trying to register a user from AD into Lotus Notes. I get all the way through the wizard until it asks me for the Certifier password. Punch in the password and I get this error message, “Wrong certifier id selected: O=HC01 does not match /O=HC01.”

I believe it’s something in my policy but I can’t figure it out. Has anyone seen this before?

Thanks in advance!
