As I said, I acn implement this feature with a SQL query as I've done:

avp_db_query("select username,domain from location where username='$tU' AND 
domain='$td'");
if ($rc == -1) {  # User not already registered.
	pua_set_publish();
}


but this jsut works fine with:
  modparam("usrloc", "db_mode", 1)
and not with:
  modparam("usrloc", "db_mode", 2)

# Database mode:
## 0 = no database
## 1 = immediately write-through
## 2 = periodically write-back
## 3 = DB-only


That's because I was looking for a way to test if a user is registered or not 
by testing the To field ($rU) of the REGISTER message.


Thanks for any help.
modparam("usrloc", "db_mode", 2)
