I'm stil confused, there is something I still miss, some joining piece - 
'ldbsearch', as You recommended use it, fail with error '-U: unknown option':
[root@dc1 samba]# ldbsearch -H ldap://dc1 -U Administrator -b 'CN=Administrator,CN=Users,DC=zamecek,DC=home' -s base nTSecurityDescriptor
Invalid option -U: unknown option
Usage: ldbsearch <options> <expression> <attrs...>
Usage: [OPTION...]
  -H, --url=URL                   database URL
  -b, --basedn=DN                 base DN
...

Should I use ldapsearch instead?

All I'm able to get is (pointing to 'sam.ldb'):

Thanks, You are right, but it is one-time password and this network is
not world-accessible. It seems as other problems I have maybe bigger ;)
