[Issue 9513] New: Enhanced debug output
by openldap-its＠openldap.org 12 Feb '26

https://bugs.openldap.org/show_bug.cgi?id=9513 Issue ID: 9513 Summary: Enhanced debug output Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: enhancement Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- While debugging ITS#9479 I needed more information on which threads were doing what actions. Also, when looking for delays/hangs/race conditions, the 1-second granularity of the debug msg timestamp was inadequate. And also, some of the debug output for the Search operation was being done in separate Debug calls for a single line of output. This gets jumbled up pretty badly if other threads are printing output as well. New patch set will extend the debug timestamp to have fractional seconds too; it will use clock_gettime for nanosecond resolution if available, otherwise use gettimeofday for microsecond resolution. Also tweak the Search debug output to only use one Debug invocation per line of output. This is MR!279. -- 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
by openldap-its＠openldap.org 10 Feb '26

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 10026] New: Refresh handling can skip entries (si_dirty not managed properly)

https://bugs.openldap.org/show_bug.cgi?id=10026 Issue ID: 10026 Summary: Refresh handling can skip entries (si_dirty not managed properly) Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Take MPR plain syncrepl with 3+ providers. When a provider's own syncrepl session transitions to persist and a it starts a new parallel session towards another host, that session always has to start as a refresh. If that refresh serves entries to us, our handling of si_dirty is not consistent: - if the existing persist session serves some of these entries to us, we can "forget" to pass the others to a newly connected consumer - same if the refresh is abandoned and we start refreshing from a different provider that might be behind what we were being served (again our consumers could suffer) - if we restart, si_dirty is forgotten and our consumers suffer even worse We might need to be told (at the beginning of the refresh?) what the end state we're going for is, so we can keep si_dirty on until then. And somehow persist that knowledge in the DB... -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10358] New: syncrepl can revert an entry's CSN

Currently investigating which part of the code that should have prevented this has let it slip.

[Issue 10344] New: Potential memory leak in function firstComponentNormalize and objectClassPretty.

https://bugs.openldap.org/show_bug.cgi?id=10344 Issue ID: 10344 Summary: Potential memory leak in function firstComponentNormalize and objectClassPretty. Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: alexguo1023(a)gmail.com Target Milestone: --- Created attachment 1071 --> https://bugs.openldap.org/attachment.cgi?id=1071&action=edit Patch: Ensure the first argument passed to `ber_dupbv_x` is not `NULL`. In `firstComponentNormalize`, the code calls `ber_dupbv_x` but ignores its return value. ```c ber_dupbv_x(normalized, val, ctx); ``` When `normalized` is `NULL`, `ber_dupbv_x` allocates a new `struct berval` and returns it; failing to capture that pointer means we lose ownership and leak the allocation. The same issue arises in `objectClassPretty`. We should follow the pattern in function `hexNormalize`, which asserts that its `normalized` argument is non-NULL before use: ```c assert(normalized != NULL); ``` -- You are receiving this mail because: You are on the CC list for the issue.
