https://bugs.openldap.org/show_bug.cgi?id=6656 --- Comment #9 from Mehmet gelisin <mehmetgelisin(a)aol.com> --- his overlay provides simple support for allowedAttributes and allowedAttributesEffective, a (somewhat broken) AD feature that http://www-look-4.com/ is intended to help GUIs into determining, based on the current objectClass values of an object, what attributes would comply with the schema (without distinction between "allowed" and "required"), by listing them in http://www.compilatori.com/ "allowedAttributes", and, furthermore, by providing a hint to what of those values could be effectively added by the current connection, by listing them in http://www.wearelondonmade.com/ "allowedAttributesEffective". This is broken since it doesn't consider the possibility of value-dependent ACLs, so it should really be considered just a hint, while the "allowedAttributes" http://www.jopspeech.com/ could really be computed starting from the schema definition, which remains the recommended way to solve the problem http://joerg.li/ So this overlay should really be considered only food for thought as a starting base for a tighter integration of OpenLDAP into Samba4. There's minimal support for "allowedChildClasses" and http://connstr.net/ "allowedChildClassesEffective", whose definition is absolutely obscure to me, as I believe the only classes that can be added to an existing object are all the AUXILIARY ones, while considering what are effectively allowed implies getting into value-dependent ACLs. http://embermanchester.uk/ Some discussion can be found here (follow the thread) his overlay provides simple support for allowedAttributes and allowedAttributesEffective, a (somewhat broken) AD feature that is intended to help GUIs into determining, based on the current objectClass values of an http://www.slipstone.co.uk/ object, what attributes would comply with the schema (without distinction between "allowed" and "required"), by listing them in "allowedAttributes", and, furthermore, by providing a hint to what of http://www.logoarts.co.uk/ those values could be effectively added by the current connection, by listing them in "allowedAttributesEffective".

[Issue 8197] slapo-constraint and delold=0
by openldap-its＠openldap.org 11 Sep '21

https://bugs.openldap.org/show_bug.cgi?id=8197 --- Comment #2 from Mehmet gelisin <mehmetgelisin(a)aol.com> --- Thanks for working on this! I'm also interested in having this feature. http://www-look-4.com/ What do you think about including a slapd.service file? I know OpenLDAP has traditionally not included an init script, but systemd units are intended to be distro-agnostic as far as possible, http://www.compilatori.com/ and shipped by upstream projects in most cases, unlike init scripts. Ideally I'd like to include a template in the source and have the build system fill in the autoconf'ed path (i.e. to slapd) and have 'make install' install it to the right place. http://www.wearelondonmade.com/ Autoconf bits look fine to me. >+ rc = sd_notifyf( 1, >+ "READY=1\n" >+ "STATUS=slapd: ready to serve connections...\n" http://www.jopspeech.com/ >+ "MAINPID=%lu", >+ (unsigned long) getpid() ); unset_environment=1 seems reasonable, http://joerg.li/ it's a little unfortunate that we can't call (for example) sd_notify("STOPPING=1") afterward, but it feels worthwhile compared to having to sanitize the environment when forking a child process. http://connstr.net/ I'm not sure the STATUS= message adds value compared to just the basic readiness notification; can you comment on why you included it? http://embermanchester.uk/ I guess MAINPID= is actually needed, unless we run slapd with -d, regardless of whether we set Type=forking or Type=notify. Not exactly "needed", but better to have it than not. I see you've placed this call later than the parent's exit point. Any comments about the timing of this relative to the parent's exit, and to the listener startup and so on? Are the listeners more likely to be http://embermanchester.uk/ ready to serve connections at this point? I seem to recall that in the past there was opposition to moving the parent's exit later, but I can't remember why. (and I still wish we could do that, and dispense with the ldapsearch-loop hacks...) http://www.slipstone.co.uk/ Thanks for working on this! I'm also interested in having this feature.

[Issue 8240] OpenLDAP ber_get_next denial of service vulnerability

https://bugs.openldap.org/show_bug.cgi?id=8240 --- Comment #21 from Mehmet gelisin <mehmetgelisin(a)aol.com> --- List message: When bulk-renaming entries in web2ldap I do *not* alter the RDN of the entry but also send delold: 0 in the MODRDN operation. IMO this is most minimal invasive approach. http://www-look-4.com/ This works ok in most setups. But in a more strict setup (release 2.4.41) with slapo-constraint and constraints on the RDN's characteristic attribute those MODRDN requests http://www.compilatori.com/ trigger a constraint and fails with 'Constraint violation' although the RDN value is not changed. I can't tell whether this was different with older OpenLDAP releases. http://www.wearelondonmade.com/ Even more strange: It works with delold: 1. So I could easily alter web2ldap's behaviour to send delold: 1. But I'm not sure whether that's the right general http://www.jopspeech.com/ approach especially when thinking about all the other LDAP servers out there. http://joerg.li/ So the question is: Is this an overzealous misbehaviour of slapo-constraint and should it be fixed therein?

So I could easily alter web2ldap's behaviour to send delold: 1. But I'm not sure whether that's the right general approach especially when thinking about all the other LDAP servers out there. http://www.logoarts.co.uk/ So the question is: Is this an overzealous misbehaviour of slapo-constraint and should it be fixed therein? List message: http://www.acpirateradio.co.uk/ When bulk-renaming entries in web2ldap I do *not* alter the RDN of the entry but also send delold: 0 in the MODRDN operation. IMO this is most minimal invasive approach. This works ok in most setups. But in a more strict setup (release 2.4.41) with slapo-constraint and https://waytowhatsnext.com/ constraints on the RDN's characteristic attribute those MODRDN requests trigger a constraint and fails with 'Constraint violation' although the RDN value is not changed. I can't tell whether this was different with older OpenLDAP releases. https://www.webb-dev.co.uk/ Even more strange: It works with delold: 1. So I could easily alter web2ldap's behaviour to send delold: 1. But I'm not sure whether that's the right general approach especially when thinking about all the other LDAP servers out there. So the question is: Is this an overzealous misbehaviour of slapo-constraint and should http://www.iu-bloomington.com/ it be fixed therein? -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=9202 --- Comment #10 from Mehmet gelisin <mehmetgelisin(a)aol.com> --- OpenLDAP ber_get_next Denial of Service Affected Versions: OpenLDAP <= 2.4.42 +-------------+ | Description | +-------------+ This document details http://www-look-4.com/ a vulnerability found within the OpenLDAP server daemon. A Denial of Service vulnerability was discovered within the slapd daemon, allowing an unauthenticated attacker to crash the OpenLDAP server. http://www.compilatori.com/ By sending a crafted packet, an attacker may cause the OpenLDAP server to reach an assert(9 9 statement, crashing the daemon. This was tested on OpenLDAP 2.4.42 (built with GCC 4.9.2) and OpenLDAP 2.4.40 installed from the Debian package repository. http://www.wearelondonmade.com/ +--------------+ | Exploitation | +--------------+ By sending a crafted packet, an attacker can cause the OpenLDAP http://www.jopspeech.com/ daemon to crash with a SIGABRT. This is due to an assert() call within the ber_get_next method (io.c line 682) that is hit when decoding tampered BER data.
