[Issue 9468] New: slapd-ldap does anonymous bind even if rebind-as-user is set

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9468 Issue ID: 9468 Summary: slapd-ldap does anonymous bind even if rebind-as-user is set Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: backends Assignee: bugs(a)openldap.org Reporter: tero.saarni(a)est.tech Target Milestone: --- When back-ldap retries bind operation after connection retry, it will do it as anonymous even if rebind-as-user is set to yes. Expected behavior is that (re)bind is done with user's credentials from the initial bind operation. I observed following (Warning: I might have understood details of the code incorrectly): When rebind-as-user is set and bind operation from client is processed, proxy will copy the credentials to ldapconn_t representing the remote LDAP connection. When remote LDAP connection is closed (e.g. by the proxy itself due to timeout), the bind credentials information is lost when freeing the old ldapconn_t. At this point, client still holds the connection to proxy and is unaware of the remote connection being lost. Proxy then re-establishes the connection and "synthetically" generates new bind itself, but since it does not have the credentials stored in memory anymore, it sends anonymous bind on behalf of the client. As a side effect, slapd currently crashes if remote server does not allow anonymous bind and responds with InvalidCredentials instead. The crash is due to assert(), which is handled in separate issue https://bugs.openldap.org/show_bug.cgi?id=9288 -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9580] New: Refresh vs. accesslog in delta-MPR

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9580 Issue ID: 9580 Summary: Refresh vs. accesslog in delta-MPR Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: replication Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- A server consuming a plain syncrepl session (might be a delta-MMR refresh) still has to log the entries into accesslog, however that accesslog stops being capable of serving as a delta-sync source: - operation entryCSNs will be out-of-order - the changes logged will not be the intended modifications (e.g. if we fell back after a conflict, the conflicting entry will be replaced with the other version, other examples available) We need to deal with that somehow, at the very least we need to make sure the consumer will not take them at face value. We could record this in the accesslog root entry if we can detect when this starts and match it up with the final cookie, syncprov would still need some tweaks to understand it. We could mark the entries received this way and make sure delta-consumers treat them as "poison", as if they were running a plain syncrepl session themselves (not update contextCSN until that's finished, mark its own accesslog entries this way, ...). Anything like that needs guarantees that it will clean itself up once all of the real plain sessions finish otherwise we've lost delta-sync altogether. A different approach might or might not be needed for live delta-persist sessions replicating from a refreshing provider, but at least that syncprov has a way of detecting this live if it chooses to. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9385] New: Opening an env with MDB_NOSUBDIR with no existing file returns error

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9385 Issue ID: 9385 Summary: Opening an env with MDB_NOSUBDIR with no existing file returns error Product: LMDB Version: unspecified Hardware: All OS: Mac OS Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: kriszyp(a)gmail.com Target Milestone: --- Created attachment 776 --> https://bugs.openldap.org/attachment.cgi?id=776&action=edit A fix to tolerate stat call on non-existing file Calling mdb_env_open with a file path to a file that doesn't exist yet, with MDB_NOSUBDIR on a non-Windows OS will return an error indicating that the file doesn't exist. This is supposed to create a new file, and works properly on the mdb.master branch, and still functions properly on Windows. The error is due to the stat() call in mdb_env_open prior to the file existing. I attached a patch that tolerates the absence of the file before checking if the file is on a block device. I am not sure if this is the appropriate fix, or if would be better to move this check later in mdb_env_open after the file is created, or alternately, determining the parent directory and calling stat on that. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9702] New: slapadd is missing -r chroot option

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9702 Issue ID: 9702 Summary: slapadd is missing -r chroot option Product: OpenLDAP Version: 2.5.7 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: dpa-openldap(a)aegee.org Target Milestone: --- I want to run slapd under chroot with the -r option. In order to initialize the setup, I want to use `slapadd -n0 configuration.ldif`. The configuration file contains mdb databases and these databases have `olcDbDirectory: ` paths. Since slapd will load the databases from the chroot environment, the directory names must be submitted to slapadd to be correct in the chroot environment. This means, that outside the chroot environment the directory paths are not correct. When I call `slapadd -n0 ` I get the error olcDbDirectory: value #0: invalid path: No such file or directory slapadd: could not add entry dn="olcDatabase={1}mdb,cn=config" (line=909): Closing DB... which means, that slapadd cannot open (outside the chrooted environment) the olcDbDirectory path. Thus slapadd shall first enter the chrooted environment, but it lacks option for this. Probably slapcat will also need this option to dump the databases. The chrooted environment is created specially for openldap, so it contains no tools. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9403] New: add option to completely disable syslog logging

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9403 Issue ID: 9403 Summary: add option to completely disable syslog logging Product: OpenLDAP Version: 2.4.45 Hardware: All OS: Linux Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: cvuillemez(a)yahoo.fr Target Milestone: --- For auditing purpose, I need to enable "stats" loglevel. So on heavy load, slapd send lots of events to local syslog socket /dev/log, when compiled with LDAP_SYSLOG (on Debian / Ubuntu). It worked fine on old systems with a simple syslog service. But when upgrading on system with journald+syslog, CPU "overhead" becomes totally crazy. It would be great to have an option at run time to completely disable syslog logging, or/and use a cutom socket, e.g. /run/systemd/journal/syslog to bypass journald service. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9675] New: Allow overwriting the default SLAPD_DEFAULT_CONFIGDIR during ./configure

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9675 Issue ID: 9675 Summary: Allow overwriting the default SLAPD_DEFAULT_CONFIGDIR during ./configure Product: OpenLDAP Version: 2.5.7 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 839 --> https://bugs.openldap.org/attachment.cgi?id=839&action=edit fix I want to have different default for SLAPD_DEFAULT_CONFIGDIR in my slapd. By calling CPPFLAGS="-DSLAPD_DEFAULT_CONFIGDIR='\"/new/config/dir/\"'" ./configure one can change the default configdir in slapd. Provided that the macro SLAPD_DEFAULT_CONFIGDIR is not changed in the code, which is ensured by the provided patch.

[Issue 9584] New: cn=config replication ops/refresh should pause server

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9584 Issue ID: 9584 Summary: cn=config replication ops/refresh should pause server Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Looking into this crash: https://git.openldap.org/openldap/openldap/-/jobs/7286 The thread in question is running a plain syncrepl refresh while another thread seems to have done the same. This thread fetched the entryUUID attribute of the 'cn=config' entry as 'a' and in the meantime, that entry has been rewritten, with 'a' presumably cleaned up and returned to the pool, so addressing a->a_nvals[0] is a NULL-dereference now. This might or might not be related to the fix in ITS#8102. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9620] New: back-monitor: search can access a persistent entry freed in the meantime

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9620 Issue ID: 9620 Summary: back-monitor: search can access a persistent entry freed in the meantime Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: backends Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- With ITS#9600 there is now code that adds and removes "persistent" monitor entries outside a server pause. A concurrent cn=monitor search lists all children first and sends them later - monitor is happy to free some of them in the meantime. It seems to me that the monitor cache should be protected by a rw mutex instead, which would be held for reading while a search is happening. -- You are receiving this mail because: You are on the CC list for the issue.

[Bug 9256] New: The ACLs required for SASL binding are not fully documented

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9256 Bug ID: 9256 Summary: The ACLs required for SASL binding are not fully documented Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: documentation Assignee: bugs(a)openldap.org Reporter: kop(a)karlpinc.com Target Milestone: --- Created attachment 727 --> https://bugs.openldap.org/attachment.cgi?id=727&action=edit Patch massaging the SASL binding requirement docs While some ACL requirements for SASL binding are documented, some are not. E.g, that olcAuthzRegexp requires =x on objectClass when direct DN mapping is not documented. Other requirements can be reasoned out based on the existing documentation, but this can be very difficult when unfamiliar with all the moving parts and the places they are documented. E.g. knowing that (objectClass=*) is the default filter, and that there's _always_ _some_ filter, and connecting this with ACLs required to do search-based SASL mapping. The attached patch brings all the SASL binding requirements together in one place in the docs and makes everything explicit. The word "SASL" is included, for those searching for that keyword.
