Either the base DN does not exist, or if it does, you are not allowed to
search it (maybe your server doesn't allow anonymous searches).

Try reading the namingContexts attribute from the root DSE (an entry with
DN of a zero-length string) to find out what the server thinks it holds:

ldapsearch -h ldap.company -b "" -s base "(objectclass=*)" namingContexts
