Summary: Refresh vs. accesslog in delta-MPR
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: replication
Severity: normal
Priority: ---
Component: overlays
Assignee: bugs(a)openldap.org
Reporter: ondra(a)mistotebe.net
Target Milestone: ---
A server consuming a plain syncrepl session (might be a delta-MMR refresh)
still has to log the entries into accesslog, however that accesslog stops being
capable of serving as a delta-sync source:
- operation entryCSNs will be out-of-order
- the changes logged will not be the intended modifications (e.g. if we fell
back after a conflict, the conflicting entry will be replaced with the other
version, other examples available)
We need to deal with that somehow, at the very least we need to make sure the
consumer will not take them at face value. We could record this in the
accesslog root entry if we can detect when this starts and match it up with the
final cookie, syncprov would still need some tweaks to understand it.
We could mark the entries received this way and make sure delta-consumers treat
them as "poison", as if they were running a plain syncrepl session themselves
(not update contextCSN until that's finished, mark its own accesslog entries
this way, ...). Anything like that needs guarantees that it will clean itself
up once all of the real plain sessions finish otherwise we've lost delta-sync
altogether.
A different approach might or might not be needed for live delta-persist
sessions replicating from a refreshing provider, but at least that syncprov has
a way of detecting this live if it chooses to.

Summary: Delta-sync MPR needs to be stable regardless of
ordering
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: replication
Severity: normal
Priority: ---
Component: backends
Assignee: bugs(a)openldap.org
Reporter: ondra(a)mistotebe.net
Target Milestone: ---
If two or more updates are spread across several providers before they have a
chance to learn about the others, all replicas need to arrive at the same
content regardless of the order in which they arrive.
One example that is broken at the moment:
- (csn a) server 1 accepts a modify
- (csn b) server 2 accepts a delete on the same DN
- (csn c) server 2 accepts an add on that DN again
If a replica receives the actions in the order bca vs. abc, the content of the
entry will be different even though the final CSN set is the same -> they will
never converge. The ordering 'bac' also needs to result in eventual
convergence, even if it means a refresh or replication from either provider
stalling temporarily?

Summary: slapd -V should be deprecated
Product: OpenLDAP
Version: unspecified

Component: slapd
Assignee: bugs(a)openldap.org
Reporter: smckinney(a)symas.com

Sometimes a user's (present one included) ignorance gets them in trouble
unnecessarily. The -V option is an example...
Normally, when one wants to determine the version of a process, they use -V, or
perhaps -v. With slapd, the daemon actually continues to run, which can have
negative consequences.
The doc clearly states that -VV is probably what the user wants, but is
counter-intutive. Who RTFM's before checking the version?
-V print version info (-VV exit afterwards, -VVV print
info about static overlays and backends)
I propose we eliminate the option to allow slapd to continue running after
displaying the version. Perhaps we eliminate the -V option entirely, or just
make it work the same as -VV.

Summary: OpenLDAP does not send port as SPN when authenticating
SASL GSSAPI
Product: OpenLDAP
Version: 2.4.44
Hardware: x86_64

Status: UNCONFIRMED
Severity: normal

Reporter: robert.wilson1717(a)gmail.com
Target Milestone: ---
When trying to authenticate to an ADLDS server using kerberos and a MIT ccache,
OpenLdap only passes the hostname to the SASL mechanism, causing a mismatch
between the SPN in the client "ldap/adlds.my.domain" and the one registered in
AD "ldap/adlds.my.domain:50000"
Is there a way fo forcing OpenLDAP to pass the port as part of the SASL
request? Or is there a part of the OpenLDAP -> Cyprus-SASL -> MIT KRB5 chain
where this can be enabled?

Summary: dynlist: member expansion when member attribute not
requested
Product: OpenLDAP
Version: 2.5
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal

Component: overlays
Assignee: bugs(a)openldap.org
Reporter: quanah(a)openldap.org
Target Milestone: ---
When configured to do dynamic "member" expansion, i.e.:
overlay dynlist
dynlist-attrset groupOfURLs memberURL member
Any query against an object that would trigger this expansion will incur a
penalty while dynlist does the expansion work even if there was no request for
the member attribute.
Currently that can be worked around by specifying the manageDSAit control when
doing a search on the object, but this may not be feasible for some client
applications and additionally other directory servers do not do this expansion
for their dynamic group implementations unless the underlying configured
attribute is explicitly requested.
We've already implemented this in dynlist for the memberOfAD case, we should do
it here as well.

Summary: API calls blocking after async connect
Product: OpenLDAP
Version: 2.4.49

Created attachment 721
--> https://bugs.openldap.org/attachment.cgi?id=721&action=edit
async connect test without TLS
My understanding of LDAP_OPT_CONNECT_ASYNC is that the attached program should
not block. If the connection does not establish fast enough, the bind call is
supposed to return LDAP_X_CONNECTING.
(At least that's how I understand it, based on the original behaviour (circa
2.4.23 up to 2.4.40) as well as the bind loop in back-meta. On the other hand,
the man page does "Subsequent calls to library routines will poll for
completion of the connect before performing further operations" which might be
interpreted as meaning they would block...)
In current releases it does block, as demonstrated by strace on Linux (latency
added using 'tc qdisc'):
[...]
connect(3, {sa_family=AF_INET, sin_port=htons(389),
sin_addr=inet_addr("192.168.1.204")}, 16) = -1 EINPROGRESS (Operation now in
progress)
write(3, "0\f\2\1\1`\7\2\1\3\4\0\200\0", 14) = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLOUT|POLLERR|POLLHUP}], 1, -1) = 1 ([{fd=3,
revents=POLLOUT}])
write(3, "0\f\2\1\1`\7\2\1\3\4\0\200\0", 14) = 14
poll([{fd=3, events=POLLIN|POLLPRI}], 1, -1) = 1 ([{fd=3, revents=POLLIN}])
read(3, "0\f\2\1\1a\7\n", 8) = 8
read(3, "\1\0\4\0\4\0", 6) = 6
write(2, "OK: ldap_simple_bind_returned 0 "..., 42OK: ldap_simple_bind_returned
0 (Success)
) = 42
[...]
As discussed in IRC, I believe I bisected this down to commit ae6347bac, from
bug 8022. The reasoning is sound, but ldap_int_open_connection does not
actually return -2, only -1 or 0.
The patch is simple enough, but I'm also looking at some later commits that
were probably done to work around this, and might not be needed now (bug 8957,
bug 8968, bug 8980). Also need to test all setups thoroughly (ldap, ldaps,
STARTTLS, not to mention back-meta/asyncmeta).
I also notice that LDAP_OPT_CONNECT_ASYNC is not effective unless
LDAP_OPT_NETWORK_TIMEOUT is also set. It might be intentional, but the man page
doesn't mention this specifically, and I don't see why it would be necessary...

Summary: Make liblutil usable by libldap
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: build
Assignee: bugs(a)openldap.org
Reporter: ryan(a)openldap.org
Target Milestone: ---
liblutil is a static library (non-PIC) and so cannot be linked into shared
objects, however we have several use cases for reusing its code in libldap.
Some options:
- moving more code from liblutil to libldap
- just merge the whole thing?
- are there components that link liblutil but _not_ libldap?
- build liblutil as PIC (take a minor performance hit when linked into
programs?)
- build liblutil twice (liblutil.a and liblutil_pic.a)
- symlink liblutil sources into libldap build dir, like libldap_r does with
libldap
- both of these last options require checking whether executables can call
the PIC symbols safely (if some symbols are used by both library and program
code)
Nice-to-have for 2.5, I'd say more likely for 2.6 at this point.

Summary: Move all replication consumer code into its own
overlay

Component: overlays
Assignee: bugs(a)openldap.org
Reporter: quanah(a)openldap.org
Target Milestone: ---
(In relation to a discussion about slapo-chain)
<hyc> anyway, the nicer ting to fix would be in 2.5, push all of the repl
consumer code into its own overlay
<hyc> in that case, updateref would be processed wherever the overlay was
configured
<hyc> so no longer tied to the frontend
<hyc> it would also make it more feasible to have multiple different consumer
configs in a single DB, each with their own provider URL (and thus their own
updateref)
<hyc> I would think we can get rid of the update ref directive entirely, just
point all writes to that consumer's provider.

From a past discussion with hyc on 2.5 items:
[13:57] <hyc> there's a nagging problem though, pcache's entry_release function
needs to distinguish between its backend actually freeing the entry, or being a
no-op
[13:57] <hyc> so it can decide whether to return success or continue
[13:58] <hyc> the patch to translucent sidesteps the question, by avoiding
other overlays
[13:58] <hyc> but we need to revisit this in 2.5
