Questions about slapo-memberof
by Alex Samad - Yieldbroker 17 Aug '23

17 Aug '23

Hi I am using slapo-memberof wondering about its performance, I have a couple of groups that have a large pool of unique member attributes. I had some maintenance code that would update the largest group - say about 4k uniquemember entries. The code is wrong it rewrite all of the attributes instead of just updating the diff. But what we noticed is that for upto 13 sec the memberof attrib could be wrong on a user object whilst I presume slapo-memberof re evaluated all of the memberships Question I am in the middle of rewritting the maintenance code - will slapo-memberof only reprocess the additions / diffs or will it reeval all ... Do I have any control over how many threads or are there any control knobs I can tune for the slapo-memberof to help with this ? Thanks Alex

slapd module thread synchronization and portability. __atomic_xxx().
by Sean Gallagher 17 Aug '23

17 Aug '23

Hi OpenLDAP affiliates, I'm working on a slapd module and have started looking at thread safety. I've noticed that lloadd uses __atomic_xx GCC builtins but slapd does not. Is there are reason for this? Does lloadd compile and run on all the same targets that slapd does? Sean. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

2.6.4 replication oddness
by Brendan Kearney 16 Aug '23

16 Aug '23

list members, i am implementing slapd 2.6.4, having had 2.4.x running for quite some time. i had 2 primary nodes with n-way multi primary replication working like a charm, and want to have 2.6.4 with 3 primary nodes. i keep running into some odd issues when i bring up all three nodes and they begin replicating between each of the nodes. i have failure messages showing the instances core-dumping and want to find why the core dumps occur. Aug 08 16:21:20 server1 systemd[1]: slapd.service: Main process exited, code=dumped, status=11/SEGV Aug 08 16:21:20 server1 systemd[1]: slapd.service: Failed with result 'core-dump'. i have enable "stats" log level, and don't get much more info. i can run one instance and seem to be working without core dumping, but if i turn up one or both of the other slapd instances, all 3 of the instances begin failing. should i bump the log level up or is there diagnostics i can run, to find the reason things are failing? any insight is greatly appreciated. if i need to provide more info, let me know what is needed. thanks in advance, brendan

Help writing a slapd plugin
by John Scott 07 Aug '23

07 Aug '23

Hi, Inspired by the proprietary server at ldap.dnssek.info, I'd like to make a slapd plugin that, when queried for a particular email address, finds the OpenPGP keys and S/MIME certificates by doing DNS lookups (possibly aided by DANE), and then serves them back to the requestor. Currently the documentation in the OpenLDAP Administrator's Guide still needs to be written. Since not a lot of software supports DANE right now, but a lot of programs *do* support LDAP, I think a bridge between the two is something that could really benefit the Internet community. Could someone steer me in the right direction on how to get started? Thanks

Idea for security module: Using dnX509peerNormalize() to validate client certificates
by Sean Gallagher 06 Aug '23

06 Aug '23

Hi OpenLDAP team, I am investigating writing a module to perform certificate validation as has been discussed in previous posts (See the "Proposal to strengthen slapd EXTERNAL authentication" thread on the openldap-technical(a)openldap.org list). The idea is to inspect the subject name on the client certificate as soon as possible after TLS is established and close the connection if it does not match some predefined pattern. This would allow client certificates signed by public CAs to be used safely with slapd. Looking through the code, I see that dnX509peerNormalize() is called almost immediately after the TLS is established and that it may be handled by a callable handler installed by the register_certificate_map_function() entry point. This would be an ideal place to inspect the certificate. The only problem being it that there is no way to "reject" a certificate and force the connection to be closed. It may be possible to use the ssl context passed into the dnX509peerNormalize() function to close the connection but this would not be very clean and likely have undesirable side effects. What would be good is if dnX509peerNormalize() could return a particular error code to signal that the connection should be immediately closed. I see that LDAP_INVALID_CREDENTIALS is already used to signal benign invalid credentials. Maybe a new error code is required. something like "LDAP_HOSTILE_CREDENTIALS". connection.c: connection_read() could then detect this and close the connection in an orderly fashion by calling connection_closing( c, "TLS Client certificate rejected" ); connection_close( c ); This would seem to be a generally useful thing to have in the slapd core. Is this something the OpenLDAP project would consider doing? Sean. -- This email has been checked for viruses by AVG antivirus software. www.avg.com
