[Issue 10265] New: Make it possible to change olcBkLloadListen at runtime
by openldap-its＠openldap.org 07 Aug '26

https://bugs.openldap.org/show_bug.cgi?id=10265 Issue ID: 10265 Summary: Make it possible to change olcBkLloadListen at runtime Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: lloadd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Currently, olcBkLloadListen changes only take effect on lloadd startup: - an added olcBkLloadListen should come online at the end of the modify operation - at the end of the modify operation a removed olcBkLloadListen will stop listening on the sockets associated with it, clients that connected over these are marked CLOSING - to facilitate replacing a value where URIs resolved sockets overlap, olcBkLloadListen should become a MAY in olcBkLloadConfig objectclass Lloadd's startup was modelled upon slapd's, but the requirements have changed considerably when it was turned into a module. Sockets are acquired at module configuration time, which is much later than standalone/slapd's own startup and so the way the URLs are handled also needs to be reworked. This will resolve other related issues. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9612] New: Change index_hash64 default to on

https://bugs.openldap.org/show_bug.cgi?id=9612 Issue ID: 9612 Summary: Change index_hash64 default to on Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Change the default value of index_hash64. By default this means slapd won't run on a 32-bit CPU (It will continue to work on 32-bit OSes running on 64-bit CPUs). If someone needs to run slapd on a 32-bit CPU they can turn this option off. In the documentation, mark the option as deprecated for eventual removal in a future release. -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=9186 Bug ID: 9186 Summary: RFE: More metrics in cn=monitor Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: backends Assignee: bugs(a)openldap.org Reporter: michael(a)stroeder.com Target Milestone: --- Currently I'm grepping metrics from syslog with mtail: https://gitlab.com/ae-dir/ansible-ae-dir-server/-/blob/master/templates/mta… With a new binary logging this is not possible anymore. Thus it would be nice if cn=monitor provides more metrics. 1. Overall connection count per listener starting at 0 when started. This would be a simple counter added to: entries cn=Listener 0,cn=Listeners,cn=Monitor 2. Counter for the various "deferring" messages separated by the reason for deferring. 3. Counters for all possible result codes. In my mtail program I also label it with the result type. -- You are receiving this mail because: You are on the CC list for the bug.

https://bugs.openldap.org/show_bug.cgi?id=10169 Issue ID: 10169 Summary: Add support for token only authentication with otp overlay Product: OpenLDAP Version: 2.6.6 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Currently the OTP overlay is password + token. It would be nice to be able to configure it so it can run in a token only mode, similar to the slapo-totp overlay in contrib. This would allow us to have a project supported solution and retire that contrib module. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10064] New: Add modrdn support for Cft_Misc entries
by openldap-its＠openldap.org 07 Aug '26

https://bugs.openldap.org/show_bug.cgi?id=10064 Issue ID: 10064 Summary: Add modrdn support for Cft_Misc entries Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Currently in cn=config, there is some special handling to maintain overlays/dbs entries to allow list-like management. All module defined entries are marked Cft_Misc and this behaviour is not available there. It boils down to allowing the module to screen rename/renumber requests and having bconfig defer to that callback if it's defined. Use-case: policy selection rules in ITS#9343 would benefit from being managed this way rather than having to reparse a long line every time a rule is adjusted. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10330] New: TIMEOUT and NETWORK_TIMEOUT not respected when receiving bad data during TLS negotiation
by openldap-its＠openldap.org 07 Aug '26

https://bugs.openldap.org/show_bug.cgi?id=10330 Issue ID: 10330 Summary: TIMEOUT and NETWORK_TIMEOUT not respected when receiving bad data during TLS negotiation Product: OpenLDAP Version: 2.6.9 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: michael.kourlas(a)solace.com Target Milestone: --- Created attachment 1063 --> https://bugs.openldap.org/attachment.cgi?id=1063&action=edit Test program This seems related to bug 8047. Steps to reproduce: 1. Setup a netcat server on a host: "nc -l -k -p 636". 2. On a different host, attempt to connect to the host running "nc" as if it were an LDAP server via ldaps: "ldapsearch -o NETWORK_TIMEOUT=5 -o TIMEOUT=5 -H ldaps://<ip>:636". 3. During the 5 second timeout period, switch back to the netcat server and transmit a newline by pressing enter. 4. ldapsearch will hang forever until the TCP connection is closed (e.g. by killing the netcat server). My expectation would be that ldapsearch would exit after 5 seconds, per the NETWORK_TIMEOUT and TIMEOUT options. I'm using the following version of ldapsearch on Fedora 41 (x86-64): > ldapsearch: @(#) $OpenLDAP: ldapsearch 2.6.9 (Mar 27 2025 00:00:00) $ > openldap > (LDAP library: OpenLDAP 20609) This problem is also observable when directly using the OpenLDAP C API. This is more of an issue, since any application using the API could become unresponsive if these timeout values aren't respected. I've attached a short test program which can be used instead of ldapsearch. If I abort the test program while it is stuck in this state, the traceback looks like this: > #0 0x00007f50b7a25811 in __GI___libc_read (fd=3, buf=0x2aaf9ac5, nbytes=3) at ../sysdeps/unix/sysv/linux/read.c:26 > #1 0x00007f50b792f8b9 in sb_debug_read (sbiod=0x2aadf390, buf=0x2aaf9ac5, len=3) > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/liblber/sockbuf.c:829 > #2 0x00007f50b7b61156 in tlso_bio_read (b=0x2aadf9c0, buf=0x2aaf9ac5 "", len=3) > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/tls_o.c:1279 > #3 0x00007f50b7221ea3 in bread_conv (bio=<optimized out>, data=<optimized out>, datal=<optimized out>, readbytes=0x7ffd1cf2e3f0) > at crypto/bio/bio_meth.c:121 > #4 0x00007f50b7226047 in bio_read_intern (b=b@entry=0x2aadf9c0, data=0x2aaf9ac5, data@entry=0x555f3588, dlen=3, dlen@entry=18446744072487067717, > readbytes=readbytes@entry=0x7ffd1cf2e3f0) at crypto/bio/bio_lib.c:285 > #5 0x00007f50b72261db in BIO_read (b=0x2aadf9c0, data=0x555f3588, dlen=-1222483899) at crypto/bio/bio_lib.c:311 > #6 BIO_read (b=b@entry=0x2aadf9c0, data=data@entry=0x2aaf9ac5, dlen=dlen@entry=3) at crypto/bio/bio_lib.c:303 > #7 0x00007f50b783ce03 in tls_default_read_n (rl=0x2aaec1c0, n=5, max=<optimized out>, extend=<optimized out>, clearold=<optimized out>, > readbytes=0x7ffd1cf2e4b8) at ssl/record/methods/tls_common.c:406 > #8 0x00007f50b784151b in tls_get_more_records (rl=0x2aaec1c0) at ssl/record/methods/tls_common.c:583 > #9 0x00007f50b783b8ea in tls_read_record (rl=0x2aaec1c0, rechandle=0x2aaeb600, rversion=0x2aaeb608, type=0x2aaeb60c "", data=0x2aaeb610, > datalen=0x2aaeb620, epoch=0x0, seq_num=0x0) at ssl/record/methods/tls_common.c:1130 > #10 0x00007f50b783969a in ssl3_read_bytes (ssl=<optimized out>, type=22 '\026', recvd_type=0x7ffd1cf2e684 "", buf=0x2aaee480 "\001", len=4, > peek=0, readbytes=0x7ffd1cf2e688) at ssl/record/rec_layer_s3.c:689 > #11 0x00007f50b784f5a7 in tls_get_message_header (s=0x2aaea980, mt=<synthetic pointer>) at ssl/statem/statem_lib.c:1554 > --Type <RET> for more, q to quit, c to continue without paging-- > #12 read_state_machine (s=0x2aaea980) at ssl/statem/statem.c:625 > #13 state_machine (s=<optimized out>, server=0) at ssl/statem/statem.c:479 > #14 0x00007f50b7b615c3 in tlso_session_connect (ld=<optimized out>, sess=0x2aaea980, name_in=<optimized out>) > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/tls_o.c:693 > #15 0x00007f50b7b65bf2 in ldap_int_tls_connect (ld=ld@entry=0x2a9b2430, conn=conn@entry=0x2a9b25d0, host=host@entry=0x2a9b2550 "192.168.133.56") > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/tls2.c:425 > #16 0x00007f50b7b6636f in ldap_int_tls_start (ld=0x2a9b2430, conn=0x2a9b25d0, srv=<optimized out>) > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/tls2.c:1245 > #17 0x00007f50b7b3d4c2 in ldap_int_open_connection (ld=0x2a9b2430, conn=0x2a9b25d0, srv=0x2a9b24d0, async=0) > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/open.c:515 > #18 0x00007f50b7b5212d in ldap_new_connection (ld=0x2a9b2430, srvlist=0x2a9b2878, use_ldsb=1, connect=<optimized out>, bind=0x0, m_req=0, m_res=0) > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/request.c:491 > #19 0x00007f50b7b3c7b4 in ldap_open_defconn (ld=0x2a9b2430) > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/open.c:42 > #20 0x00007f50b7b52ed8 in ldap_send_initial_request (ld=0x2a9b2430, msgtype=96, dn=0x4023a9 "cn=admin,dc=solace,dc=com", ber=0x2a9b2570, msgid=1) > at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/request.c:131 > #21 0x00007f50b7b429b9 in ldap_sasl_bind (ld=0x2a9b2430, dn=0x4023a9 "cn=admin,dc=solace,dc=com", mechanism=0x0, cred=0x7ffd1cf2eb90, sctrls=0x0, > cctrls=0x0, msgidp=0x7ffd1cf2eb8c) at /usr/src/debug/openldap-2.6.9-1.fc41.x86_64/openldap-2.6.9/libraries/libldap/sasl.c:164 -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9431] New: back-mdb: Always have an equality index for objectClass
by openldap-its＠openldap.org 07 Aug '26

https://bugs.openldap.org/show_bug.cgi?id=9431 Issue ID: 9431 Summary: back-mdb: Always have an equality index for objectClass Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: backends Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Data storage backends require an equality index on objectClass to function correctly. As this is a hard requirement it should be automatic with back-mdb. Why this wasn't done in the past with other backends isn't exactly clear, it may have been due to their requirements to have additional cache layers. That however is not necessary with back-mdb. -- You are receiving this mail because: You are on the CC list for the issue.
