[Issue 9363] New: removing olcReadOnly on a DB does not set it to FALSE
by openldap-its＠openldap.org 22 Jun '21

22 Jun '21

https://bugs.openldap.org/show_bug.cgi?id=9363 Issue ID: 9363 Summary: removing olcReadOnly on a DB does not set it to FALSE Product: OpenLDAP Version: 2.4.53 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: maxime.besson(a)worteks.com Target Milestone: --- Created attachment 771 --> https://bugs.openldap.org/attachment.cgi?id=771&action=edit ldif config that reproduces the issue I am running the following test: * add olcReadOnly: TRUE on a MDB database in cn=config * Try to write to the MDB database => fails with "unwilling to perform" as expected * remove the olcReadOnly attribute from the MDB database * Try to write to the MDB database => still fails with the same error * Restart slapd * Try to write to the MDB database => OK However the following test works as expected: * add olcReadOnly: TRUE on a MDB database in cn=config * Try to write to the MDB database => fails with "unwilling to perform" as expected * modify olcReadOnly to FALSE on the MDB database * Try to write to the MDB database => OK It seems a little counter intuitive to me that removing a setting does not reset it to its default value. The fact that a slapd restart make writing possible again in the first test described above makes it seem to the casual user that olcReadOnly cannot be undone without a restart at all. Tested in 2.4.53 and 2.4.44, config attached but it probably works with any config (hdb, etc) -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9512] New: Add ability to restrict by client ip address in ACLs
by openldap-its＠openldap.org 14 Jun '21

14 Jun '21

https://bugs.openldap.org/show_bug.cgi?id=9512 Issue ID: 9512 Summary: Add ability to restrict by client ip address in ACLs 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: --- Currently it is possible via ACLs to enforce restrictions based on which slapd host interface is connected to via the peername parameter. However, it's not possible to enforce ACL restrictions based on the IP address used by the client. This would be a useful feature when wanting to restrict certain DNs to only being able to have access if they connect from a certain IP or IP range. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9537] New: slap_timestamp() can give a duplicated timestamp across restarts
by openldap-its＠openldap.org 04 Jun '21

https://bugs.openldap.org/show_bug.cgi?id=9537 Issue ID: 9537 Summary: slap_timestamp() can give a duplicated timestamp across restarts 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: --- On busy sites, when a slapd restart takes <1s, accesslog can fail to log changes with LDAP_ALREADY_EXISTS. This is because slap_timestamp() only logs timestamps with a 1s precision, disambiguating the rest with a counter that's forgotten across restarts. It is possible my analysis in ITS#9487 is partially invalidated because of this. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9526] New: slapadd -w crashes

Invalid argument (22) > slapadd: couldn't create context entry > Closing DB... This is because: * mdb_tool_next_id() takes dead global [tools.c`static MDB_cursor *mcp] for further operations * cursor is dead because mdb_tool_entry_put() didn't initialized it * mdb_tool_entry_put() didn't initialized cursor because it thinks it is initialized, because there is an active global [tools.c`MDB_txn *mdb_tool_txn] * transaction was initialized by mdb_tool_dn2id_get(), which doesn't care about cursors. Long story short: the global state in tools.c is not managed consistently and needs rethinking. -- You are receiving this mail because: You are on the CC list for the issue.

There doesn't appear to be any valid reason for this change, and it causes the cache to be unresponsive to new searches while expiration is removing cached entries. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9295] New: ppolicy and replication: pwdLockedTime replication fails to replicate

Replica has schemachecking=on in its syncrepl configuration b) account gets locked on the replica, so pwdAccountLockedTime is set on the replica but not on the provider(s) c) admin does a MOD/ADD op against a provider for the user entry to add a value to pwdAccountLockedTime dn: ... changetype: modify add: pwdAccountLockedTime pwdAccountLockedTime: ... d) provider accepts this modification. e) replica rejects this modification because the resulting change means that there would be two pwdAccountLockedTime values on the account in question Generally I believe that in this scenario, the MOD/ADD on the provider should be treated as a replace OP instead of an ADD op -- You are receiving this mail because: You are on the CC list for the issue.
