No. Anyway, note that query return correctly 'result: 0 Success',
simply return no data.
Another query to the same DC return data. eg:

 root at vdmpp1:~# ldapsearch -H ldap://vdcpp1.ad.fvg.lnf.it -W -D CN=mta,OU=Restricted,DC=ad,DC=fvg,DC=lnf,DC=it -b DC=ad,DC=fvg,DC=lnf,DC=it "(cn=prova123)" rfc822MailMember | grep ^rfc822MailMember
 Enter LDAP Password: 
 root at vdmpp1:~# 
 root at vdmpp1:~# ldapsearch -H ldap://vdcpp1.ad.fvg.lnf.it -W -D CN=mta,OU=Restricted,DC=ad,DC=fvg,DC=lnf,DC=it -b DC=ad,DC=fvg,DC=lnf,DC=it "(uid=gaio)" uid | grep ^uid
 Enter LDAP Password: 
 uid: gaio

Seems really to me an ACL trouble, note also:

 root at vdmpp1:~# ldapsearch -H ldap://vdcpp1.ad.fvg.lnf.it -W -D CN=gaio,OU=Users,OU=SanVito,OU=FVG,DC=ad,DC=fvg,DC=lnf,DC=it -b DC=ad,DC=fvg,DC=lnf,DC=it "(cn=prova123)" rfc822MailMember | grep ^rfc822MailMember
 Enter LDAP Password: 
 rfc822MailMember: gaio
 rfc822MailMember: marco.gaiarin

But how can i check ACLs data on different DCs?

I've checked 'samba-tool testparm', /etc/krb5.conf, /etc/hosts,
/etc/resolv.conf: all are the same (names and ips docet).
