https://bugs.openldap.org/show_bug.cgi?id=6598 --- Comment #20 from Mehmet gelisin <mehmetgelisin(a)aol.com> --- If non-anonymous access is needed, the slapd.access(5) manpage needs an > update too.

It http://www.wearelondonmade.com/ is the authenticated ID that needs access in both cases. On further thought I think it is correct that the access is checked without reference to whether that ID has access to entry and parent entries, as (particularly in the case of authzFrom) http://www.jopspeech.com/ the authenticated ID may not have any direct access to the entry whose ID it is about to assume. http://joerg.li/ Thus, if principal A has authenticated and wishes to perform an operation using principal B's authorisation, the access required is: A needs auth access to authzTo in its own entry if that attribute is involved in giving A permission to act for B. http://connstr.net/ A needs auth access to authzFrom in B's entry if that attribute is involved in giving A permission to act for B. The rules are the same whether using a SASL authorization identity or using a ProxyAuth control on an LDAP operation. http://embermanchester.uk/ Thus I think my original report was wrong.

[Issue 5963] Explictly deleting all object classes and re-add some fails in modify request

I strongly concur with Hallvard here. http://www.iu-bloomington.com/ > Every use of assert is "assert(the code is correct)" - but that often depends > on dynamic state, not just the statically written code. Yes, dynamic state including invalid input. But IMO "assert(the code is correct)" should never be hit no matter how bad the input was. And it should definitely not crash the server (with system's ressource limits being a https://www.webb-dev.co.uk/ unavoidable exception). Rephrasing: The meaning of the statement "the code is correct" should also include "invalid input is properly handled as error" - no matter what. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 6656] logging "reqEntryUUID" in accesslog

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

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
by openldap-its＠openldap.org 11 Sep '21

11 Sep '21

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?

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.

by openldap-its＠openldap.org 10 Sep '21

10 Sep '21

https://bugs.openldap.org/show_bug.cgi?id=9672 Issue ID: 9672 Summary: Permit static linking with libsasl2 Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: build Assignee: bugs(a)openldap.org Reporter: dpa-openldap(a)aegee.org Target Milestone: --- Created attachment 838 --> https://bugs.openldap.org/attachment.cgi?id=838&action=edit pkg-config + libsasl2 = ♥ I want to link slapd statically. First I link openssl and libsasl2 statically. The static libsasl2 bundles all SASL plugins, and linking towards it must be done (in my case) with -lcrypto. The check in configure.ac: ``` AC_CHECK_LIB(sasl2, sasl_client_init, [ol_link_sasl="-lsasl2"], [AC_CHECK_LIB(sasl, sasl_client_init, [ol_link_sasl="-lsasl"])]) ``` fails, since -lcrypto is not passed during linking with the static -lsasl2 . `pkg-config --statit libsasl2 --libs` knows how to link statically with libsasl2 and it knows, whether libsasl2 is installed. The applied patch does linking/preprocessing of libsasl2 by utilizing pkg-config, when available. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9676] New: slapadd -n0 does need -F parameter, despite the documentation
by openldap-its＠openldap.org 10 Sep '21

https://bugs.openldap.org/show_bug.cgi?id=9676 Issue ID: 9676 Summary: slapadd -n0 does need -F parameter, despite the documentation Product: OpenLDAP Version: 2.5.7 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: dpa-openldap(a)aegee.org Target Milestone: --- My reading of the documentation of slapadd is, that when `slapadd -n0 -linit0.ldif` is called, and the default config directory exists, and is empty, sladadd will create the cn=config database in the default config directory. ``` -F confdir specify a config directory. If both -f and -F are specified, the config file will be read and converted to config directory format and written to the specified directory. If neither option is specified, an attempt to read the default config directory will be made before trying to use the default config file. If a valid config directory exists then the default config file is ignored. If dry-run mode is also specified, no conversion will occur. ``` My default config directory is "/data/config" ( CFLAGS="-DSLAPD_DEFAULT_CONFIGDIR='\"/data/config\"' ) calling strace slapadd -n0 -linit0.ldif prints: [pid 573949] newfstatat(AT_FDCWD, "/data/config", <unfinished ...> [pid 573949] <... newfstatat resumed>{st_mode=S_IFDIR|0755, st_size=4096, ...}, 0) = 0 [pid 573949] mmap(NULL, 1052672, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0 <unfinished ...> [pid 573949] <... mmap resumed>) = 0x7f050183a000 [pid 573949] gettimeofday( <unfinished ...> [pid 573949] <... gettimeofday resumed>{tv_sec=1631220679, tv_usec=401535}, NULL) = 0 [pid 573949] openat(AT_FDCWD, "/data/config/cn=config.ldif", O_RDONLY <unfinished ...> [pid 573949] <... openat resumed>) = -1 ENOENT (No such file or directory) [pid 573949] munmap(0x7f050183a000, 1052672 <unfinished ...> [pid 573949] <... munmap resumed>) = 0 [pid 573949] newfstatat(AT_FDCWD, "//etc/openldap/slapd.conf", <unfinished ...> [pid 573949] <... newfstatat resumed>0x7ffda7228410, 0) = -1 ENOENT (No such file or directory) [pid 573949] write(2, "slapadd: bad configuration file!\n", 33 <unfinished ...> So it fails.

[Issue 9665] New: wrong indentation in ldap_int_bisect_find
by openldap-its＠openldap.org 07 Sep '21

07 Sep '21

https://bugs.openldap.org/show_bug.cgi?id=9665 Issue ID: 9665 Summary: wrong indentation in ldap_int_bisect_find Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: roland.illig(a)gmx.de Target Milestone: --- In abandon.c, ldap_int_bisect_find has an incorrectly indented if statement. I stumbled upon this due to a lint warning and immediately wondered who forgot to format the code again, probably after removing a redundant outer if statement or loop. The wrong indentation was introduced by https://git.openldap.org/openldap/openldap/-/commit/2660518c5d924b2b6377a87… in 2008. -- You are receiving this mail because: You are on the CC list for the issue.
