[Issue 9972] New: SSS needs READ instead of SEARCH access
by openldap-its＠openldap.org 07 Aug '26

07 Aug '26

https://bugs.openldap.org/show_bug.cgi?id=9972 Issue ID: 9972 Summary: SSS needs READ instead of SEARCH access Product: OpenLDAP Version: 2.6.3 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: dpa-openldap(a)aegee.org Target Milestone: --- I have configured an OpenLDAP 2.6 server with dn: olcDatabase=mdb,cn=config objectClass: olcDatabaseConfig objectClass: olcMdbConfig olcDatabase: mdb olcAccess: to dn="cn=bodies,dc=aegee,dc=org" by * search # no problem if this is READ olcAccess: to dn.sub="dc=aegee,dc=org" by * read … dn: olcOverlay=sssvlv,olcDatabase={1}mdb,cn=config objectClass:olcOverlayConfig The content of the tree is available anymously by calling ldapsearch -ZZxH ldap://ldap.aegee.org -b "dc=aegee,dc=org" -s sub . When I modify the call to use SSS: ldapsearch -ZxH ldap://ldap.aegee.org -b "dc=aegee,dc=org" -s sub -E sss=ou:2.5.13.15 it also returns results, but ends with ``` # search result search: 93 result: 50 Insufficient access # numResponses: 3 # numEntries: 2 ``` When I modify above: olcAccess: to dn="cn=bodies,dc=aegee,dc=org" by * read then the access is sufficient. There is no entry called "dn:cn=bodies,dc=aegee,dc=org", or rather the entry shall not be returned on searches and `ldapsearch -ZxH ldap://ldap.aegee.org -b "dc=aegee,dc=org" -s sub` does not return it. These work without a problem: ldapsearch -ZxH ldap://ldap.aegee.org -b "cn=bodies,dc=aegee,dc=org" -s one -E sss=ou:2.5.13.15 ldapsearch -ZxH ldap://ldap.aegee.org -b "cn=bodies,dc=aegee,dc=org" -s sub ldapsearch -ZxH ldap://ldap.aegee.org -b "cn=bodies,dc=aegee,dc=org" -s one This produces Insufficient access: ldapsearch -ZxH ldap://ldap.aegee.org -b "cn=bodies,dc=aegee,dc=org" -s sub -E sss=ou:2.5.13.15 That said client-side-sorting does work without a problem, but server-side sorting requires not only SEARCH, but also READ privileges on dn="cn=bodies,dc=aegee,dc=org". I find this is a bug: SSS requires read-acesss to data, which is not supposed to be returned to the client (dn:cn=bodies,dc=aegee,dc=org). For the additional server-side sorting no additional privileges shall be required, compared to returning the results without server-side-sorting. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9816] New: slapcat cordeumps during mdb subtree dump with -s

https://bugs.openldap.org/show_bug.cgi?id=9816 Issue ID: 9816 Summary: slapcat cordeumps during mdb subtree dump with -s Product: OpenLDAP Version: 2.5.11 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: khoffmann(a)united-internet.de Target Milestone: --- Created attachment 887 --> https://bugs.openldap.org/attachment.cgi?id=887&action=edit gdb backtrace of slapcat run When trying to use slapcat in combination with -b and -s in order to create a LDIF backup of a mdb subtree, slapd crashes with a coredump (please see the attached snippet with gdb output from a reproduced test tree). The problem was reporducible with different mdb databases / suffixes and only appears with option -s. The same dump with -H 'ldap:///ou=users,o=company,c=de??sub?' instead of -s ou=users,o=company,c=de works perfectly fine, as long as the "attrs part" is empty in the ldap-uri. Also using slapcat with -b only (for a full database dump) works fine as well. I'm aware of the fact that -s option is marked as DEPRECATED - I'm not sure if you are going to fix this bug or if you rather take the change to remove the option completely from future major versions. Please let me also know if it's expected behaviour that the -H option doesn't work whenever the attribute part isn't empty and if I should contribute to a documentation update for this edge case.

[Issue 9786] New: liblber: missing export of ber_pvt_wsa_err2string

https://bugs.openldap.org/show_bug.cgi?id=9786 Issue ID: 9786 Summary: liblber: missing export of ber_pvt_wsa_err2string Product: OpenLDAP Version: 2.6.1 Hardware: All OS: Windows Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: tobias.junghans(a)veyon.io Target Milestone: --- When building (cross-compiling) OpenLDAP via GCC/mingw-w64, an undefined reference to ber_pvt_wsa_err2string() is reported when libldap.dll is linked. This can be fixed easily by adding ber_pvt_wsa_err2string() to libraries/liblber/lber.map -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9902] New: Make max index DBs for back-mdb configurable
by openldap-its＠openldap.org 07 Aug '26

https://bugs.openldap.org/show_bug.cgi?id=9902 Issue ID: 9902 Summary: Make max index DBs for back-mdb configurable Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: backends Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- From ITS#9895: Currently there is a hardcoded limit of 128 index DBs in back-mdb. Some sites want more than this (although there's no evidence they actually use more than 128 attributes in all of their applications' search filters). For 2.5/2.6 we can simply double the constant. For 2.7 consider making it configurable. Note that increasing the number increases the size of an LMDB transaction structure, and also increases the time needed to initialize it whenever creating a transaction, so it's a bad idea to just set this to an arbitrarily large number. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9748] New: Deleted values of pwdFailureTime seem to reappear

In the attached accesslog, trace, deletion of everything (including "20211115154510.478330Z") is recorded from reqSession: 3, then a bind comes in and the same value is explicitly removed again. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9393] New: Provider a LDAP filter validation function

https://bugs.openldap.org/show_bug.cgi?id=9393 Issue ID: 9393 Summary: Provider a LDAP filter validation function Product: OpenLDAP Version: 2.4.56 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: best(a)univention.de Target Milestone: --- In many situations I need to validate if a user submitted LDAP filter has valid syntax. It seems there is no official function to check this. Could you provide one? libraries/libldap/filter.c: ldap_pvt_put_filter() can be used as a basis. -- My current workaround is using a unconnected ldap connection and do a search with that filter. This yields a FILTER_ERROR (invalid filter) or a SERVER_DOWN error (invalid filter).

[Issue 10013] New: Some code (ppolicy, etc.) ignores REP_CTRLS_MUSTBEFREED when touching rs->sr_ctrls

https://bugs.openldap.org/show_bug.cgi?id=10013 Issue ID: 10013 Summary: Some code (ppolicy, etc.) ignores REP_CTRLS_MUSTBEFREED when touching rs->sr_ctrls 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: --- Certain parts of the source indicate that rs->sr_ctrls shouldn't be realloc'd/free'd unless REP_CTRLS_MUSTBEFREED is set, but then other parts of slapd (slap_ctrl_whatFailed_add, glue_op_search?, ...) and overlays (ppolicy, syncprov, ...) will blindly overwrite and/or realloc it. slap_add_control() (an analog of slap_add_controls()) might be useful for this, possibly alongside some way to free the other data kept around to streamline the code other users need for correct operation. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9768] New: slapo-translucent handling of deletion of multi-valued configuration attributes removes wrong value from list
