I added a -d option (picked 10), and discovered that it wanted the full name
as specificed in the certificate. That fixed ldapwhoami and I put that in
ldap.conf, smb.conf, and in sssd.conf, but sssd is still not behaving (samba
is though, mostly -- it might also be having issues since sssd is not
working)...
