Would it be possible to check serverID during slapd startup with MMR setup and fail to start with an error message in case serverID is 0? Ciao, Michael.

test062 segfault with back-mdb

This doesn't occur with back-bdb/hdb, and it doesn't happen if I insert a sleep after the ldapsearch to see if slapd is running, before the modification to cn=config is done.

autoca SEGV with OpenSSL 1.1
by Quanah Gibson-Mount 19 Apr '17

19 Apr '17

The new autoca overlay is broken with OpenSSL 1.1 after fixing the code to pull in the correct headers. Specifically, we get a segfault in the OpenSSL's libcrypto. Looking at the docs, it appears the code is correct on the OpenLDAP side of things? So perhaps a bug in OpenSSL (I'm using 1.1.0e, the latest release). Backtrace shows: Program received signal SIGSEGV, Segmentation fault.

Status of ldap_init_fd and LDAP_PROTO_EXT?
by Volker Lendecke 15 Apr '17

15 Apr '17

Hi! What's the status of those two? They are mentioned in the manpages of for example Debian Jessie and FreeBSD 11 (maybe from ports?), but the manpage explicitly says you have to #include <ldap_pvt.h>, which is not shipped. What's the reason of them being in ldap_pvt.h? Are they supposed to change in the future? The function is now more than 10 years old, without too much change in that decade. Not being able to fully asynchronously connect to a server was my main reason to start my own little ldap library a few years ago, so I think this can be useful code :-) Thanks, Volker

None of those are a target use case. If you're running infrastructure for a lot of different domains, you are probably already using some other full-blown CA. My primary use for this is quick setup within a single domain. Typically for private networks. No web browser is going to recognize an auto-generated CA cert, so it's not really suited for (nor intended for) certificates that will be used by a general public. > c) While there is an option to specify the keysize, there is no option to > specify the digest to use.

But if you can suggest an attribute that the overlay can read to retrieve multiple DNS names it could of course be added. > > --Quanah > > -- > > Quanah Gibson-Mount > Product Architect > Symas Corporation > Packaged, certified, and supported LDAP solutions powered by OpenLDAP: > <http://www.symas.com> > > > -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Some immediate things I see after reading the man page for the current autoca are: a) Not going to work well for databases that use "" as a suffix, and then support multiple domains beneath that (Zimbra had many customers that did this.
