When OpenSSL extends that API, all versions of OpenLDAP with thie patch will also support those extensions with no additional code. -- You are receiving this mail because: You are on the CC list for the issue.

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.

[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 9972] New: SSS needs READ instead of SEARCH access

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 9902] New: Make max index DBs for back-mdb configurable

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.

I used openldap as krb5's database, and openldap was deploymented in mirrormode. I tried to add kerberos principals via kadmin.local -q "addprinc -randkey principal. slapd log showed that the entry of kadmin/admin was added earlier than the entry of ossuser. But the csn of kadmin/admin was greater than ossuser. In this case, when the two entry began to sync to the other slapd server, ossuser was ignored because of "csn not new enough" -- You are receiving this mail because: You are on the CC list for the issue.
