[Bug 1891548] Re: autofs-ldap's /etc/ldap/schema/autofs.schema crashes slapd
Since this appears to have just required a fix to autofs, I'm closing the openldap task.

[Bug 1891548] Re: autofs-ldap's /etc/ldap/schema/autofs.schema crashes slapd
Hi Michael and thanks for all the digging. If I understand correctly there are two issues here: 1. The slapd crash due to the caseExactMatch/caseExactIA5Match typo, for which you submitted a fix upstream [1]. 2. The need to "start ; stop ; restart" the slapd service in order to avoid the "invalid per syntax" errors. What I suggest is to: A. Let's wait for upstream to comment on or pickup your patch. We'll then be able to cherry-pick the fix from the upstream repository. This makes things easier to manage and give us more confidence on the correctness on the patch (could be obvious for a ldap/autofs expert, I am not.) B. File a separate bug for the "start ; stop ; restart" thing, which appears to be unrelated. If you do so, please make it clear it's a Bionic -> Focal regression. Having a minimal steps to reproduce the issue from a fresh Focal install would be the best. What do you think?

[Bug 1891548] Re: autofs-ldap's /etc/ldap/schema/autofs.schema crashes slapd
I didn't realize that this was considered unusual. AutoFs integration has been a critical part of our infrastructure across multiple departments at our university for decades, starting with NIS/NIS+. Without AutoFS integration we would be ... very, very sad. I have filed a bug report w/ Debian and included a patch against Debian Sid's autofs-5.1.6 source package: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968675 Since this is the same source file as Ubuntu 20.04 uses I've included the patch file for your use, on the off chance that it would make things easier (attached). Looking at the up-stream source from https://mirrors.edge.kernel.org/pub/linux/daemons/autofs/v5/ it appears that version 5.1.2's autofs.schema file was correct. The typo first appears in 5.1.3, released in May 24th 2017, and has affected every release of autofs since. I have also submitted a bug report, including a patch file, to the aut...@vger.kernel.org mailing list for the autofs developers.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Since this affects an unusual end-user configuration, I'm setting Importance to Low, and I don't expect anyone to work on this soon. However if you can help definitively explain what needs adjusting to fix this correctly, then that would be helpful and we can try to help get that fix landed. Caveat: normally we'd expect an explanation and patch to be sent to Debian first.

Re: [Bug 1891548] Re: autofs-ldap's /etc/ldap/schema/autofs.schema crashes slapd
As a follow-up, I figured out a workaround for the following error that I reported earlier: adding new entry "ou=auto.master,dc=example,dc=org"ldap_add: Invalid syntax (21) additional info: objectClass: value #1 invalid per syntax Original steps: 1) Install /etc/ldap/slapd.conf (which includes the "caseExactIA5Match" fixed version of the autofs schema) 2) Start slapd 3) Attempts to enter an automountMap entry causes an invalid syntax error Workaround: 1) Install /etc/ldap/slapd.conf (which includes the "caseExactIA5Match" fixed version of the autofs schema) 2) start slapd 3) stop and restart slapd again 4) Attempts to enter automountMap entry now succeed Why this is necessary I can't say but the behavior is consistent. This extra restart was not necessary for versions of slapd+autofs that shipped with 18.04 and previous Ubuntu versions. Also I'm going to further show my ignorance here and say that I found "caseExactMatch" in several other schema files too. I'm wondering why other users haven't run into something similar? # find /etc/ldap/schema/ -type f -exec grep -q caseExactMatch {} \; -print/etc/ldap/schema/corba.schema/etc/ldap/schema/duaconf.ldif/etc/ld ap/schema/core.schema <-- commented out/etc/ldap/schema/duaconf.schema/etc/ldap/schema/java.schema/etc/ldap /schema/core.ldif <-- commented out/etc/ldap/schema/java.ldif/etc/ldap/schema/autofs.schema Thank you again for your help on this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891548 Title: autofs-ldap's /etc/ldap/schema/autofs.schema crashes slapd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/autofs/+bug/1891548/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1891548] Re: autofs-ldap's /etc/ldap/schema/autofs.schema crashes slapd
msp3k is correct. The bug is in autofs-ldap, not in slapd. slapd is correct to reject "caseExactMatch" since the attribute syntax is IA5 String. The correct fix is what msp3k said, fix the matching rule to be caseExactIA5Match like it was in the old one. --- /etc/ldap/schema/autofs.schema 2020-08-14 15:50:36.678109301 + +++ /etc/ldap/schema/autofs.schema 2020-08-14 15:50:46.506246431 + @@ -10,7 +10,7 @@ attributetype ( 1.3.6.1.4.1.2312.4.1.2 NAME 'automountInformation' DESC 'Information used by the autofs automounter' - EQUALITY caseExactMatch + EQUALITY caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE ) objectclass ( 1.3.6.1.4.1.2312.4.2.3 NAME 'automount' SUP top STRUCTURAL -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891548 Title: autofs-ldap's /etc/ldap/schema/autofs.schema crashes slapd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/autofs/+bug/1891548/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode. To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1891548/+editstatus and add the package name in the text box next to the word Package.
