Problems with binaries of samba version 3.0.0rc2

Hello, I try aid. I have some problems with the version 3.0.0rc2 of samba.

i) I'm looking for to compile the samba version 3.0.0rc2 with
 HAVE_LDAP = 1 and HAVE_KRB5 = 1, but there are some errors in file pdb_ldap.c.

1) Line 2242 incompatible type in assignment in function          pdb_init_ldapsam_common
2) Line 2325 incompatible type in assignment in function          pdb_init_ldapsam


ii) The executable rpcclient don' t function with the option -N, because it asks the password.
