[Issue 9817] New: rwm overlay : Issue with DN containing special characters

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9817 Issue ID: 9817 Summary: rwm overlay : Issue with DN containing special characters Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: thierry.pubellier(a)paris.fr Target Milestone: --- Hi, I'm using rwn to select the database useg for bind operations based on the result of a rewriteMap requets. Sample configuration in global section : #Rewrite Map to request a remote server rwm-rewriteMap ldap checkEntry "ldap://10.1.2.3/ou=users,dc=paris,dc=local?dn?sub" binddn="cn=myuser,ou=users,dc=paris,dc=local" credentials="XXX" # Backing up original DN rwm-rewriteRule ".+" "${&binddn($0)}$0" ":" # Contructing LDAP Filter for remote search. Combined with a rewrite Map, the requested DN is returned if there is a match. rwm-rewriteRule ".+" "(&(!(description=TEST))(distinguishedName=$0))" ":" # If filter matches, end of rewriting. Going to 'dc=paris,dc=local' database rwm-rewriteRule ".+" "${checkIfPasswordExpiredDN($0)}" ":@I" # Otherwise, restoring the original DN. rwm-rewriteRule ".+" "${*binddn}" ":" # And final DN massaging from "dc=paris,dc=local" to "dc=paris,dc=local2" database rwm-rewriteRule "(.+,)?ou=users,dc=paris,dc=local$" "$1ou=users,dc=paris,dc=local2" ":@" Everything goes fine until I use DN with special characters, like ',' or '['. For example : 'cn=Pubellier\, Thierry (TEST),ou=users,dc=paris,dc=local' In this case, the rwm-rewriteRule contructs a LDAP filter with incorrect syntax, as special caracters are not being escaped. I have to use some ugly tricks to escape these caracters, as shown below : #Rewrite Map to request a remote server rwm-rewriteMap ldap checkEntry "ldap://10.1.2.3/ou=users,dc=paris,dc=local?dn?sub" binddn="cn=myuser,ou=users,dc=paris,dc=local" credentials="XXX" # Backing up original DN rwm-rewriteRule ".+" "${&binddn($0)}$0" ":" # Rewriting for ',' rwm-rewriteRule "(.+).\2C(.+)" "$1\\,$2" # Adding a special '#' (asserting it in none of my DNs) suffix for special characters, in order to escape them without looping forever rwm-rewriteRule "(.*)([)*(\\])([^#].*|$)" "$1$2#$3" # Escaping of special characters with dedicated '#' suffix, avoiding infinite loops rwm-rewriteRule "(.*)([)*(\\])#(.*)" "$1\\$2$3" # Contructing LDAP Filter for remote search. Combined with a rewrite Map, the requested DN is returned if there is a match. rwm-rewriteRule ".+" "(&(!(description=TEST))(distinguishedName=$0))" ":" # If filter matches, end of rewriting. Going to 'dc=paris,dc=local' database rwm-rewriteRule ".+" "${checkIfPasswordExpiredDN($0)}" ":@I" # Otherwise, restoring the original DN. rwm-rewriteRule ".+" "${*binddn}" ":" # And final DN massaging from "dc=paris,dc=local" to "dc=paris,dc=local2" database rwm-rewriteRule "(.+,)?ou=users,dc=paris,dc=local$" "$1ou=users,dc=paris,dc=local2" ":@" Could there be a way to integrate the ldap escape mechanism when making an variable assignment (like using a '#' character in place of the usual '&') ?

[Issue 9358] New: back-mdb may return accesslog entries out of order

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9358 Issue ID: 9358 Summary: back-mdb may return accesslog entries out of order Product: OpenLDAP Version: 2.4.53 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- back-mdb will usually return search entries in entryID order, but may do a dn traversal instead if the count of children is smaller than the count of search filter candidates. The RDNs are sorted in length order, not lexical order. For accesslog, all RDNs are of equal length but if they have trailing zeroes, the generalizedTime normalizer truncates them. Changing their lengths causes accesslog's timestamp-based RDNs to sort in the wrong order. The least intrusive fix is to override the syntax/normalizer for reqStart and reqEnd attributes to not truncate trailing zeroes. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9516] New: Argon2 configuration parameters with slappasswd

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9516 Issue ID: 9516 Summary: Argon2 configuration parameters with slappasswd Product: OpenLDAP Version: 2.4.58 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: gilbert.kowarzyk(a)servicenow.com Target Milestone: --- It is currently possible to generate an Argon2 hash using slappasswd as follows: slappasswd -h {ARGON2} -o module-load=pw-argon2 However, I believe that it is currently not possible to provide Argon2 configuration values for parameters "m", "t", and "p" when using slappasswd. If it is currently possible to provide these config parameters when using slappasswd, please add documentation for how to do so.

[Issue 9596] New: Python test suite

We can't lose it as it is also portable, but something should be introduced for developers/CI on more modern systems and increase coverage.

[Issue 9726] New: Admin guide and man pages need better documentation on disabling syslog

by openldap-its＠openldap.org

However, there is no documentation on the new settings or examples of how to do this in the admin guide, and the man page sections on the new parameters for the logfile side do not note at when/how they enable bypassing syslog. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9735] New: [PATCH] try hard to find free space if database cannot grow

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9735 Issue ID: 9735 Summary: [PATCH] try hard to find free space if database cannot grow Product: LMDB Version: 0.9.24 Hardware: All OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: libor.peltan(a)nic.cz Target Milestone: --- Created attachment 851 --> https://bugs.openldap.org/attachment.cgi?id=851&action=edit Patch fixing the issue "try hard to find free space if database cannot grow" Note: - the issue is the same in version 0.9.70 (git) Situation: - the database had already grown to its limit (mapsize) in the past - overflow pages are used heavily as stored values are usually several pages long - free space got fragmented Problem: - attempt to insert new value results in MDB_MAP_FULL despite there is free space available Cause: there is a heursitic in mdb_page_alloc() that gives up searching for free space chunk if this would take too much time. This is useful when the database can still grow, as it balances performance with space usage. However, if the database can no longer grow, it prevents inserting new values. Solution: detect early on in mdb_page_alloc() if the database can grow, and if not, let it try hard to search for free space. Patch: attached -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9782] New: regression test its8752 failure

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9782 Issue ID: 9782 Summary: regression test its8752 failure 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: --- If a contextCSN update (new cookie) goes from server A through server B to server C, server C will use that CSN to update entryCSN as well (which neither A nor B did). This fails the initial replication check. The issue has likely existed since deltasync was made possible, a version of this is confirmed at least in 2.4.60 onwards to current master. In principle, it is related to concerns raised in ITS#9580. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9642] New: Adding a task to runqueue doesn't wake the main thread

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9642 Issue ID: 9642 Summary: Adding a task to runqueue doesn't wake the main thread 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: --- If a connection adds a new syncrepl stanza, that is not started until the main thread comes around to doing it. However if that thread is currently stuck in SLAP_EVENT_WAIT() and nothing else happens (like an unbind over the connection that modified the config), the task is never started. This can take a long time. No idea yet how to wake it up with/from ldap_pvt_runqueue_insert() given that sits within libldap and not really something that should be calling slap_wake_listener(). -- You are receiving this mail because: You are on the CC list for the issue.
