Sorry. I forgot to tell you, I checked the postfix logs to count the
number of mails sent. I did this, because I received multiple complaints.
Some subscribers received the mail and others didn't.

The mails were not rejected/held, lost recipients didn't appear in the log 
file either. 
It was August and there were not many sendings on that date/time and server. 
Unfortunately the complaints reached me one month later, yesterday. The list 
owner was on vacation.

I discarded the hypothesis of a LDAP failure because both updates return the 
same number of subscribers, 1026.
I think both updates were right. 

Thanks in adavnce.
