samba - Jan 2005 - Samba 3.x auth. and idmap_rid on RedHat AS 2.1

I try to use idmap_rid with Samba/Winbind authentication for Windows on Active
Directory. The authentication works fine but I'm unable to compile the
idmap_rid module.

Here is my configuration options:
./configure --prefix=/usr --sysconfdir=/etc/samba \
--localstatedir=/var/samba --with-ldap --with-ads \
--with-smbmount --with-pam --with-pam_smbpass \
--with-winbind --with-configdir=/etc/samba \
--with-logbasedir=/var/log/samba \
--with-shared-modules=idmap_rid


Here is the error:
Compiling sam/idmap_rid.c with -fPIC
sam/idmap_rid.c: In function `rid_idmap_parse':
sam/idmap_rid.c:55: parse error before `sid_str'
sam/idmap_rid.c:58: parse error before `tok'

sam/idmap_rid.c:103: `known_domain' undeclared (first use in this function)
make: *** [sam/idmap_rid.po] Error 1


I searched for docs about idmap_rid but I didn't find to much info. If
someone could help me on that it would be appreciated.

Thanks,
