[Bug 1102366] [NEW] libapache2-mod-php5: Segmentation fault on mediawiki POST requests after apache2 reload
Public bug reported: This is the affected following setup: * apache2-mpm-worker * libapache2-mod-php5 * mediawiki (all from quantal in my case). After doing /etc/init.d/apache2 reload, POST requests to mediawiki (e.g. page preview or save) fail with a lost connection. The log files only show a line like this: [Mon Jan 21 12:21:06 2013] [notice] child pid 16018 exit signal Segmentation fault (11) Doing /etc/init.d/apache2 restart works around the problem. This seems to be the same as http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=691318 and possibly http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=694473 . I'm blaming PHP for now, in accordance with the upstream reporters. :-) Creating a backtrace from the apache child processes has proved quite challenging, so I'm stopping here.

[Bug 616719] Re: slow group indexing when using huge ldap
Klaus: in an environment of this size, I strongly recommend against using libnss-ldap, because it just doesn't scale well enough. Please try installing nslcd and libnss-ldapd (notice the d), get it running, after that add nscd again, and evaluate if this better fits your needs. If it doesn't, you might also have a look at sssd and libnss-sss, but AFAICR that's only really available starting from maverick. BTW both these daemons come with their own pam packages, which replace libpam-ldap. -- slow group indexing when using huge ldap https://bugs.launchpad.net/bugs/616719 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libnss-ldap in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 423252] Re: NSS using LDAP on Karmic breaks 'su' and 'sudo'
Howard, I have longingly looked at libnss-ldapd for almost 4 years now, and absolutely agree it has a better architecture, cleaner code etc., and is a sensible long-term migration path. (The other possibly being sssd.) But multiple test migrations in my LDAP deployments always turned up some show-stopper problem or another. The last of these happend 3-4 months ago with ubuntu workstations, running an up-to-date karmic client-side (actually triggered by trying to work around exactly this bug). If the server team decides they want to try migrating for lucid, i'd be the first to offer help testing. But I sure don't see this happening before lucid+1. Disclaimer: haven't tried the caching slapd with nssov yet, only nslcd, because i need at least an incremental migration path. -- NSS using LDAP on Karmic breaks 'su' and 'sudo' https://bugs.launchpad.net/bugs/423252 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libnss-ldap in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 423252] Re: NSS using LDAP on Karmic breaks 'su' and 'sudo'
@Andreas: wow, that explains a lot, especially why installing nscd seems to help. Because if nscd is not running, the libnss_ldap function getpwnam() resolves to will run in process, and someone in there (libgnutls ?) does the priviledge drop. Good catch, let's investigate further. ** Changed in: sudo (Kairos Linux) Importance: Undecided = High ** Changed in: sudo (Kairos Linux) Status: New = Confirmed ** Changed in: sudo (Kairos Linux) Assignee: (unassigned) = Philipp Kaluza (pixelpapst) -- NSS using LDAP on Karmic breaks 'su' and 'sudo' https://bugs.launchpad.net/bugs/423252 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libnss-ldap in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 489418] Re: Strange behavior of libkrb5 since karmic ...
I think Sam was proposing to pull this new version as an update into karmic. The SRU guidelines state that this should hit lucid first, before we ask for an SRU. (Since this bug is a bit high-profile, it might make sense to speed up this process by uploading a dedicated bugfix package to lucid in any case.) The changes sure look reasonable enough, debdiff attached (except that you have to wade through a lot of .ps diff lines). ** Attachment added: debdiff from krb5-1.7dfsg~beta3 to krb5-1.7+dfsg, most of which is a diffed postscript file http://launchpadlibrarian.net/36269050/krb5_1.7%2Bdfsg-3.debdiff -- Strange behavior of libkrb5 since karmic ... https://bugs.launchpad.net/bugs/489418 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to krb5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

However, by now they ripped out all of Hula's LDAP connectivity, which makes this a very pretty but useless solution for SmallBusinessServer. -- Groupware Server https://blueprints.edge.launchpad.net/ubuntu/+spec/groupware-server -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 218899] Re: upgrade to hardy: user openldap is not added to group sasl
I can confirm this. While this setup doesn't seem too common, it's certainly a valid and supported one. This needs to be adressed on the slapd side, so reassigning this. The suggested fix (adduser openldap sasl) is quite simple, won't cause any regressions, but does give the slapd process some more priviledges. However, giving daemons access to /etc/sasldb2 is what the sasl group is _for_, after all. An alternative might be to force use of saslauthd, provide an configuration upgrade path, test thoroughly,and document that direct access to sasldb2 is no longer supported, I'd really recommend the former, though. :) ** Changed in: openldap2.3 (Ubuntu) Sourcepackagename: cyrus-sasl2 = openldap2.3 Status: Incomplete = Confirmed -- upgrade to hardy: user openldap is not added to group sasl https://bugs.launchpad.net/bugs/218899 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openldap2.3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
