It's building a custom LDAPDN object from an internal data structure to be used with ldap_dn2str(). The use-case for such flag/pointer ownership for others may be limited as I suspect not so many build their own LDAPDN objects from scratch.

In our case the pointer/allocated string ownership is preferable moved to the LDAPAVA object for both the value and attribute as the char* does not have the same lifetime as the LDAPAVA object.

(ITS#8940) FR: LDAP_AVA_FREE_ATTR in ldapava_free()
by erik＠halon.se 30 Nov '18

30 Nov '18

Full_Name: Erik Lax Version: 2.4.46 OS: Linux URL: Submission from: (NULL) (212.85.68.184) Hi, It's possible to set the flag LDAP_AVA_FREE_VALUE to clear ber values on the LDAPAVA structure in ldapava_free() but it's not possible to set the LDAP_AVA_FREE_ATTR to clear attributes. I suspect OpenLDAP internals does not need to free attributes in this way (hence the missing code). I'm building a custom LDAPAVA (LDAPDN) object and it would be useful to be able to set this flags to have it properly clean up both values and attributes in ldap_dnfree(). https://github.com/openldap/openldap/blob/master/libraries/libldap/getdn.c#…

(ITS#8939) back-sql broken, backsql_oc_get_attr_mapping() fails
by jl＠conductive.de 25 Nov '18

25 Nov '18

Full_Name: Joel Linn Version: 2.4.45 as well as git OS: Ubuntu (docker image) URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (37.120.2.83) Hi, I wanted to use back-sql and tried against our Firebird database, as that didn't work i spun up a Postgres container with the data from the sources. For both cases it seems the backend is broken as it reports empty fields when loading the attribute mappings, although they are definetly not empty: 5bfaced6 backsql_oc_get_attr_mapping(): executing at_query "SELECT sel_expr_u,sel_expr,from_tbls,join_where,add_proc,delete_proc,param_order,expect_return,name FROM ldap_attr_mappings WHERE oc_map_id=?" for objectClass "document" with param oc_id=2 5bfaced6 backsql_oc_get_attr_mapping(): required column #0 "name" is empty I played with the sources (moved the snprintf/DEBUG code before the field checking section that generates the error, around line 370 in schema-map.c) and found out that the first 3 columns are always null, you can confirm that by defining the at_query in slapd.conf and swapping the field names around. My guess is the binding in backsql_BindRowAsStrings is faulty. As I said i tried two different ODBC drivers. full log https://pastebin.com/4B2wjCLp configuration https://pastebin.com/JMwVVMDx

The ITS is only used for reporting bugs. In general you should follow instructions in the OpenLDAP admin guide: https://www.openldap.org/doc/admin24/replication.html For asking usage questions please subscribe to openldap-technical mailing list and post your question there: https://www.openldap.org/lists/mm/listinfo/openldap-technical You should describe what you want to achieve, the exact version you're using, OS platform, the config you've tried and some relevant log excerpts if available. Ciao, Michael.
