Re: [MonetDB-users] MCinitClient() and user oid.

In this last case, how do I know what are the admissible values for oids?
It seems to me that the oids are obtained in the authentication phase. 
Essentially in AUTHcheckCredentials() in mal_authorize.mx, and 
specifically in this piece of code (when setting uid*):
...
if (b && BATcount(b) > 0) {
                BATiter bi = bat_iterator(b);
if (*scenario == NULL || strNil(*scenario)) {
                        BBPunfix(b->batCacheid);
                        /* of course we DO NOT tell the exact reason here again */
                        throw(INVCRED, "checkCredentials", INVCRED_INVALID_USER " '%s'",*username);
                }
/* ok, there are some tuples that we have to consider */
                BATloop(b, p, q) {
                        tmp = (str)BUNtail(bi, p);
                        assert (tmp != NULL);
                        if (strcmp(*scenario, tmp) == 0) {
                                /* YAY!  fun!  party!  We are granted access! */
                                *uid = *id;
                                BBPunfix(b->batCacheid);
                                return(MAL_SUCCEED);
                        }
                }
BBPunfix(b->batCacheid);
                /* uh oh... that we made it till here means it's wrong */
                throw(INVCRED, "checkCredentials", INVCRED_INVALID_USER " '%s'",  *username);
        } else {
                /* no scenario restriction applies, so everything is good */
                if (b)
                        BBPunfix(b->batCacheid);
                *uid = *id;
                return(MAL_SUCCEED);
        }
In my situation, this authentication is triggered by a MAL call to 
mal.mapiclient, which under the hood calls MSscheduleClient(), which 
itself calls AUTHcheckCredentials().

All the best,
