I tested this patch in a 20000 user test Samba/openldap domain and it
worked ok when I was connecting in as root. When winbindd on a member
server connects anonymously or as a non-priv user with --set-auth-user I
get "smbldap_open: cannot access LDAP when not root.." errors in the logs.
I added become_root and unbecome_root calls in rpc_server/srv_samr_nt.c
before and after the calls to the new pdb interface methods to work around
