[Issue 10360] New: delta-sync can apply old mods
by openldap-its＠openldap.org 17 Sep '25

https://bugs.openldap.org/show_bug.cgi?id=10360 Issue ID: 10360 Summary: delta-sync can apply old mods Product: OpenLDAP Version: 2.6.9 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- This might be related to #10358, but not sure. In delta MPR, if an older mod is received on an entry after a newer mod has already been applied by a local user, the older mod is applied and the newer mod is lost. The incoming replication ops are checked for freshness by check_csn_age() but that only checks the incoming cookieCSN against contextCSNs of the same SID. I.e., that check only prevents duplicate mods being replicated multiple times from the same remote provider. If check_csn_age() passes, then syncrepl_message_to_op() is invoked which just applies the mod. It doesn't check the mod or cookieCSN against the entry's current entryCSN. The code in syncrepl_op_mod() performs the checks we need. The code just needs to be pulled into a new function so it can be used in both places. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10383] New: slapd-meta ignores olcDbIDAssertBind if olcDbURI defined after it

https://bugs.openldap.org/show_bug.cgi?id=10383 Issue ID: 10383 Summary: slapd-meta ignores olcDbIDAssertBind if olcDbURI defined after it Product: OpenLDAP Version: 2.6.9 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: david.frickert(a)protonmail.com Target Milestone: --- Hi, We are using slapd-meta to connect an OpenLDAP server to another external LDAP server and it works well on first configuration. However, if we want to update any info, e.g. the external LDAP URI, we must replace the olcDbURI attribute. This means that the ordering of the attributes change and this attribute is now defined after olcDbIDAssertBind. Didn't think this would be important, but after this change the "meta" connection stops working and upon enabling debugging i can see that the external LDAP server is responding with: "ldap_bind: Inappropriate authentication (48) additional info: Anonymous Simple Bind Disabled" This seems to imply that the olcDbIDAssertBind attribute is being ignored, likely due to being defined before olcDbURI (my assumption). Is this intended? If so, what can we do to mitigate this problem? Do we need to perform a replace on all attributes of the object to ensure correct ordering, or is there any way to perform an in-place attribute modification without making it shift its position in the object? Example: First configuration (OK): # {0}uri, {2}meta, config dn: olcMetaSub={0}uri,olcDatabase={2}meta,cn=config objectClass: olcMetaTargetConfig olcMetaSub: {0}uri --> olcDbURI: ldap://REDACTED/ou=users,REDACTED olcDbIDAssertBind: bindmethod=simple starttls=yes tls_reqcert=demand binddn="REDACTED" credentials="REDACTED" olcDbRewrite: {0}suffixmassage REDACTED REDACTED olcDbKeepalive: 0:0:0 olcDbBindTimeout: 100000 olcDbCancel: abandon After URI update (NOK): # {0}uri, {2}meta, config dn: olcMetaSub={0}uri,olcDatabase={2}meta,cn=config objectClass: olcMetaTargetConfig olcMetaSub: {0}uri olcDbIDAssertBind: bindmethod=simple starttls=yes tls_reqcert=demand binddn="REDACTED" credentials="REDACTED" olcDbRewrite: {0}suffixmassage REDACTED REDACTED olcDbKeepalive: 0:0:0 olcDbBindTimeout: 100000 olcDbCancel: abandon --> olcDbURI: ldap://REDACTED/ou=users,REDACTED The olcDbURI attribute is shifted to the bottom after a modify operation, and seems to cause these issues.

[Issue 10380] New: file logger doesn't emit slapd startup/version info

https://bugs.openldap.org/show_bug.cgi?id=10380 Issue ID: 10380 Summary: file logger doesn't emit slapd startup/version info Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- When using syslog, a startup message is emitted which is useful in many different contexts: - signals a slapd restart to the admin - shows the actual version used - if a crash happened just before, there is no "stopped" message, this is a hint to anyone looking that something was not right and the slapd is not the same process - people writing log processing scripts (incident response) know when it's necessary to reset their state, again as it's a new process Because of the above, it feels like a regression to me. I guess we can just emit this info on logfile config handlers? This means startups and logfile switches are still handled as they used to in syslog and log rotation doesn't emit anything (making it easy and safe to just concatenate files). Yes, slapd logs its PID in most formats so restarts can be detected that way, but that's considerably harder to search for. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10254] New: Allow upgrading password hash on bind
by openldap-its＠openldap.org 08 Sep '25

https://bugs.openldap.org/show_bug.cgi?id=10254 Issue ID: 10254 Summary: Allow upgrading password hash on bind Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: me(a)floriswesterman.nl Target Milestone: --- Many OpenLDAP installations are likely to contain relatively old password hashes such as SSHA and CRYPT, as modern alternatives such as Argon are only recent additions. Due to the nature of password hashes, it is of course not possible to "unhash" the old values and rehash them with a more modern algorithm. The presence of these old password hashes poses a liability in case of information leaks or hacks. Currently, the only way to upgrade a password hash is to wait for the user to change their password. This can be sped up by expiring passwords and forcing users to change them. However, this can be slow and frequent password rotation is no longer considered a best practice. It would be a very helpful addition to add support for upgrading a password hash on bind. This is implemented in the 389 directory server: https://www.port389.org/docs/389ds/design/pwupgrade-on-bind.html Essentially, when a user binds, the password is checked like normal. In case of a successful bind, the proposed feature would check the hash algorithm used for the password; and in case it is not equal to the current `olcPasswordHash` value, the user-provided password is rehashed using the new algorithm and stored. This way, the old hashes are phased out more quickly, without being a disturbance to users. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9343] New: Expand ppolicy policy configuration to allow URL filter

https://bugs.openldap.org/show_bug.cgi?id=9343 Issue ID: 9343 Summary: Expand ppolicy policy configuration to allow URL filter Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Currently, ppolicy only supports a single global default policy, and past that any policies must be manually added to a given user entry if they are supposed to have something other than the default policy. Also, some sites want no default policy, and only a specific subset to have a policy applied to them. For both of these cases, it would be helpful if it were possible to configure a policy to apply to a set of users via a URL similar to the way we handle creating groups of users in dynlist -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10304] New: Unable to remove item from directory as part of transaction if it is the last item in that directory

I am not 100% certain if this is an issue with OpenLDAP or liblmdb, but I have been running tests in the repo and it looks like the liblmdb tests work fine, so I think it's with OpenLDAP itself. I have been performing a transaction, and deleting entries from a directory during this transaction. This works fine if the item that I am deleting isn't the last entry in its directory, but when it is I get a MDB_NOTFOUND error on the commit transaction call and the delete doesn't go through.

[Issue 10371] New: tools don't print useful error codes

That is incorrect; ldap_result() always returns -1 on errors. The actual return code must be retrieved using ldap_get_option(ld, LDAP_OPT_RESULT_CODE,...). So up till now the tools have never printed the actual error message that's relevant to whatever failure occurred. Other applications appear to have copied this erroneous behavior.
