Hi,

why haven't written this as idmap module?

try to add a file sam/idmap_text.c and put all stuff in there.

you need something like this at the end of the file:

static struct idmap_methods text_methods = {
	text_idmap_init,
	text_allocate_rid,
	text_allocate_id,
	text_get_sid_from_id,
	text_get_id_from_sid,
	text_set_mapping,
	text_idmap_close,
	text_idmap_status
};

NTSTATUS idmap_ldap_init(void)
{
	return smb_register_idmap(SMB_IDMAP_INTERFACE_VERSION, "text", 
&text_methods);
}

above of this you just need to implement your versions of the 
text_idmap_init,text_allocate_rid,text_allocate_id,text_get_sid_from_id,text_get_id_from_sid,text_set_mapping,text_idmap_close,text_idmap_status
functions...

take a look at include/idmap.h and and sam/idmap_ldap.c for the 
prototypes of this functions

you later can choose your backend by "idmap backend = text" in smb.conf
