In addition, this messages started do appear in the logs.

[2005/02/18 10:37:17, 3] lib/smbldap.c:smbldap_connect_system(866)
  ldap_connect_system: succesful connection to the LDAP server
  ldap_connect_system: LDAP server does not support paged results

Any ideas?
Wrong LDAP Server configuration?

Best regards,
Bruno Guerreiro

Can you try to reproduce this against 3.0.11?  Thanks.
