Setting up a Mail Server (Postfix) on 11.1?

Sorry to bang on about this mail server stuff! But . .
Can anyone tell me what YaST is trying (but not very well) to tell me?

Taking it line by line (I’ll be back for line 2 later): Yes, agree that this computer is configured as an LDAP client. I can even logon as an LDAP registered user. But the LDAP server service IS local. Why does YaST think that it is remote? What does “remote” mean? How is it making this conclusion? And most importantly, does it matter?

If I click Next, I’m invited to enter the LDAP password, which I can do without any reported problems.
