[Issue 9277] New: restart 3+ providers at once burns CPU forever
by openldap-its＠openldap.org 14 Oct '20

14 Oct '20

https://bugs.openldap.org/show_bug.cgi?id=9277 Issue ID: 9277 Summary: restart 3+ providers at once burns CPU forever Product: OpenLDAP Version: 2.4.50 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: michael(a)stroeder.com Target Milestone: --- I have tiny VMs configured as Æ-DIR servers, 5 providers (multi-provider replication) and 5 read-only consumers each syncing with all providers. Restarting all consumers at once simply works, no matter how many of the providers are up. Restarting only two providers at once also works. But when restarting more than two providers at once all of thems seem to hang eating up CPU. It could be the same issue like ITS#8650 / ITS#9210 but those only mention GNUTLS being affected. But all my Æ-DIR test servers run slapd built against OpenSSL (openSUSE, Debian buster, CentOS7). -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9330] New: Need to fully serialize delta-syncrepl

https://bugs.openldap.org/show_bug.cgi?id=9330 Issue ID: 9330 Summary: Need to fully serialize delta-syncrepl Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- While using delta-syncrepl was supposed to fully serialize updates due to the use of the accesslog DB, in extremely high write driven environments it became clear this wasn't entirely the case. This would cause systems to constantly go into mini REFRESH states as changes came in out of order. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9317] New: LDAPS connection fails to multi-IP DNS using DIGEST-MD5 mechanism
by openldap-its＠openldap.org 17 Sep '20

17 Sep '20

https://bugs.openldap.org/show_bug.cgi?id=9317 Issue ID: 9317 Summary: LDAPS connection fails to multi-IP DNS using DIGEST-MD5 mechanism Product: OpenLDAP Version: 2.4.46 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: paul.raines(a)gmail.com Target Milestone: --- Our MS AD ldap servers are in DNS using alias ldap.example.org at multiple IP addresses like so: # host ldap.example.org ldap.example.org has address 172.18.1.10 ldap.example.org has address 172.21.1.10 ldap.example.org has address 172.24.1.10 ldap.example.org has address 172.30.1.10 For CentOS 6 this was not a problem. But with CentOS 7 (2.4.44) and CentOS 8 (2.4.46) the following fails # ldapwhoami -d -1 -H ldaps://ldap.example.org -Y DIGEST-MD5 -U username -W with the error: ldap_sasl_interactive_bind_s: Invalid credentials (49) additional info: 80090303: LdapErr: DSID-0C090574, comment: The digest-uri does not match any LDAP SPN's registered for this server., data 0, v3839 ldap_free_connection 1 1 ldap_send_unbind If one reverse DNS IP lookups one of the IPs and uses the unique name (e.g. ldap01.example.org) instead it works fine I think openldap should work in this case with DNS aliases. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9315] New: FR: Support SPIFFE Certificate Provisioner
by openldap-its＠openldap.org 17 Sep '20

https://bugs.openldap.org/show_bug.cgi?id=9315 Issue ID: 9315 Summary: FR: Support SPIFFE Certificate Provisioner Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: dar(a)xoe.solutions Target Milestone: --- Created attachment 754 --> https://bugs.openldap.org/attachment.cgi?id=754&action=edit A SPIFFE samle certificate SPIFFE is a protocol for attesting workload identities. It implements a pull based workflow where clients request ad-hoc certificates about their identity from a unix domain socket. While there is a helper that can wrap clients it is uncertain how certificate rolls, which happen by default every few minutes, shall be signalled to the ldap client: https://github.com/spiffe/spiffe-helper I assume there is no signal which induces graceful reloading of the certificates. Therefore, it might be considerable adding direct spiffe support to the ldap client. See example: https://github.com/spiffe/c-spiffe/blob/master/c-spiffe.cc Please find attached a spiffe sample cert, for mere information. Note it does convey identity (exclusively) through SAN, which currently seems not be supported in OpenLDAP. I'm going to open another issue for that. -- You are receiving this mail because: You are on the CC list for the issue.
