Eventually, this got on top of my priority list, and it's now implemented in HEAD. One needs to: - set LDAP_OPT_NETWORK_TIMEOUT to a value greater than 0 - set LDAP_OPT_CONNECT_ASYNC to TRUE - perform the first operation asynchronously (e.g. ldap_sasl_bind(3)) the library call might return LDAP_X_CONNECTING if poll(2)'ing after connect(2) didn't succeed yet and LDAP_OPT_NETWORK_TIMEOUT didn't expire yet. In that case, the client should resubmit the request until it either succeeds or LDAP_OPT_NETWORK_TIMEOUT expires. Note that, right now, there's no means to set LDAP_OPT_CONNECT_ASYNC other than via ldap_set_option(3), and none is foreseen, because only specially crafted clients would be able to handle LDAP_X_CONNECTING appropriately. Please test. p. Ing. Pierangelo Masarati OpenLDAP Core Team SysNet s.n.c.

The LDAP client will hang > forever (or until the server ephemeral port is closed). Is it an option for you to use Start TLS instead of ldaps? In this case, code in right HEAD should fix all non-blocking issues, as soon as you specify a network timeout and LDAP_OPT_CONNECT_ASYNC (undocumented yet, it's been committed just hours ago). The usage I suggest is to set LDAP_OPT_NETWORK_TIMEOUT to a positive value; then set LDAP_OPT_CONNECT_ASYNC to TRUE before performing the first operation, and reset it to FALSE after the first operation succeeds. In your case, the first operation would be ldap_start_tls[_s](3). p. Ing. Pierangelo Masarati OpenLDAP Core Team SysNet s.n.c.

Because somewhere a constraint stepped in, which requires objectClasses in ldap_objectclasses to be structural; it makes sense, all in all. p. Ing.

Pierangelo, the problem is indeed with the meta-data: the object at the root of the sql tree "dc=sql,dc=example,dc=org" was defined purely as dcObject, it needs a structural objectClass in order to be valid. If we define it as an organizationalUnit and dcObject (using ldap_entry_objclasses) then all works as expected. Oddly doing the opposite doesn't seem to work.

(ITS#4796) Contribution: JLDAP support for simple paging of results (RFC 2696)
by radovan＠skolnik.info 06 Jan '07

06 Jan '07

Full_Name: Radovan Skolnik Version: JLDAP CVS version OS: Windows/Java URL: http://www.skolnik.info/LDAPPagedResults.zip Submission from: (NULL) (82.119.120.128) Hello, I hope this is the right place to make this submission ;-) Recently I found that JLDAP does not support simple paging mechanism via control as stated in RFC2696 (control OID 1.2.840.113556.1.4.319). So I made an attempt to implement it and it seems to me it works as it's supposed to. I would like to contribute it to the project for the benefit of others. The files can be found at http://www.skolnik.info/LDAPPagedResults.zip If there is something more needed from me please let me know. Best regards Radovan Skolnik

Hm, according to CVS, it was removed from the release man page slapd.conf(5) in 2.1.21, May 2003. There's certainly no trace of it in the 2.3.27 man page. Ah, it's still in the Admin Guide... You should be more specific next time. -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc OpenLDAP Core Team http://www.openldap.org/project/
