(ITS#8911) Open LDAP 2.4 MMR with delta-sync replication
by sakshi.mittal＠india.nec.com
Full_Name: Sakshi Mittal
Version: 2.4.44
OS: Centos7
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (14.140.114.207)
We are trying to setup MMR with delta sync replication in OpenLDAP 2.4.44.
We have two provider servers and 2 consumer servers. We have setup delta sync
replication between the provider and consumer servers.
Now we want to configure MMR between the two provider servers.
But it does not seem to work together with delta sync.
I have tried setting up MMR separately and it works also delta sync replication
also works separately.
Can you please help in configuring the two together also please let me know if
this is even possible. As on some sites it is written that OpenLDAP 2.4 does not
support MMR together with delta-sync replication.
Please confirm.

As far as point 2 is concerned I was basing it on this piece of code, where
it looks like MDB_GET_MULTIPLE just checks some flags and then goes to the
fetchm label where the code does nothing but retrieve data:
case MDB_GET_MULTIPLE:
if (data == NULL || !(mc->mc_flags & C_INITIALIZED)) {
rc = EINVAL;
break;
}
if (!(mc->mc_db->md_flags & MDB_DUPFIXED)) {
rc = MDB_INCOMPATIBLE;
break;
}
rc = MDB_SUCCESS;
if (!(mc->mc_xcursor->mx_cursor.mc_flags & C_INITIALIZED) ||
(mc->mc_xcursor->mx_cursor.mc_flags & C_EOF))
break;
goto fetchm;
case MDB_NEXT_MULTIPLE:
if (data == NULL) {
rc = EINVAL;
break;
}
if (!(mc->mc_db->md_flags & MDB_DUPFIXED)) {
rc = MDB_INCOMPATIBLE;
break;
}
rc = mdb_cursor_next(mc, key, data, MDB_NEXT_DUP);
if (rc == MDB_SUCCESS) {
if (mc->mc_xcursor->mx_cursor.mc_flags & C_INITIALIZED) {
MDB_cursor *mx;
fetchm:
mx = &mc->mc_xcursor->mx_cursor;
data->mv_size = NUMKEYS(mx->mc_pg[mx->mc_top]) *
mx->mc_db->md_pad;
data->mv_data = METADATA(mx->mc_pg[mx->mc_top]);
mx->mc_ki[mx->mc_top] = NUMKEYS(mx->mc_pg[mx->mc_top])-1;
} else {
rc = MDB_NOTFOUND;
}
}
break;

Looks like you're right. Since these are DUPs the key would be the same=

every time so there's no need to return it on each call.<br>

The doc is correct here. The cursor is advanced far enough that a<br>
MDB_NEXT_MULTIPLE will return the following data, as opposed to just<br>
returning the same data again.<br>

Probably not a bad thing overall, but for consistency it's now patched
to set INAPPROPRIATE_AUTH as with the other cases.

Thanks for the quick fix! Not sure why rc's value is preserved here but
set to LDAP_INAPPROPRIATE_AUTH in all other failing cases, though. But
that doesn't seem to matter beside debug logs now showing a return value
other than 48, disclosing the actual reason of the failure; for instance
<== slap_sasl_authorized: return 16
SASL Proxy Authorize [conn=1022]: proxy authorization disallowed (16)
for a missing authTo under authz-policy "all".

The doc is correct here. The cursor is advanced far enough that a
MDB_NEXT_MULTIPLE will return the following data, as opposed to just
returning the same data again.
