samba - Jul 2003 - Will pam_smbpass.so work with Samba3.0beta ???

When I've been trying that :

authpam: unable to dlopen(/usr/lib/pam_smbpass.so)
authpam: [dlerror: /usr/lib/pam_smbpass.so: Undefined symbol
"sidmap_attr_list"]
authpam: adding faulty module: /usr/lib/pam_smbpass.so

Now I see  pam_smbpass can't work with new idmap feature (Samba3.0)

Before I use  Samba 2.2.7 with ldap_sam and
pam_smbpass.so module work great.
