(ITS#6026) Don't run autosaved test scripts
by rein＠OpenLDAP.org 16 Mar '09

16 Mar '09

Full_Name: Rein Tollevik Version: CVS HEAD OS: Irrelevant URL: Submission from: (NULL) (81.93.160.250) Submitted by: rein When running the entire test suite it happily includes autosaved versions of the test scripts. Which can be a bit annoying if the scripts are edited with an editor that loves to leave autosave files around.. A fix is coming. Rein Tollevik Basefarm AS

Re: (ITS#6018) TLS memory leak

As you methioned, I move ldap_set_option() with NULL to the main thread. And, I also use libldap_r instead of libldap. A specific handler is really only used in a single thread. In every thread, it always returns NULL, because it is just a test code and it always print "connect ok" while it is running. I think memory leak may happen when the code of openLDAP uses openssl function such as initialize connection in ldap_start_tls_s(). For every thread, there may be some special structures for SSL/TLS which need to be freed after the end of the thread. I find that Windows has a function ldap_stop_tls_s() related to ldap_start_tls_s(). For my software, I want to create processes instead of threads to avoid this problem.

I'm not discussing the case of this specific option, nor of its side-effects, if any, as I didn't investigate it and I'm not specifically familiar with that portion of code. > { > printf("ldap_set_option LDAP_OPT_X_TLS_REQUIRE_CERT failed\n"); > return NULL; > } > } > > if( transMethod == LDAP_TRANS_TLS ) > { > rc = ldap_start_tls_s( ld, NULL, NULL ); > if( rc != LDAP_SUCCESS ) > { > printf("ldap_start_tls_s failed\n"); > return NULL; > } > } > > if( binddn != NULL && bindpwd != NULL ) > { > rc = ldap_bind_s(ld, binddn, bindpwd, LDAP_AUTH_SIMPLE); > if ( LDAP_SUCCESS != rc ) > { > printf("ldap_bind_s failed\n"); > return NULL; > } > } This code is filled with "return NULL;" without cleaning up memory if anything goes wrong.

(ITS#6025) ldapdelete cannot handle base64 encoded dns
by quanah＠OpenLDAP.org 15 Mar '09

15 Mar '09

Full_Name: Quanah Gibson-Mount Version: RE24/HEAD OS: NA URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.111.29.239) As noted in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=334354 the OpenLDAP ldapdelete utility cannot handle base-64 encoded DNs, even though the other ldap* tools can. It would add to the tool consistency for ldapdelete to conform with the other tools in this respect. --Quanah

(ITS#6024) Don't send cookie with without csn field

Full_Name: Rein Tollevik Version: CVS HEAD OS: Irrelevant URL: Submission from: (NULL) (84.215.36.97) Submitted by: rein Syncprov sends a cookie to its consumer even when it doesn't have any csn values, i.e the cookie will only have the rid= and sid= fields. This can happen during initial load (as in test050) when a syncrepl consumer enters the present phase before the provider have finished the refresh phase with its own provider. This doesn't seem to harm the consumer, as it appears to silently ignore these cookies. But it can be confusing for somone trying to analyze the logs.. A fix is coming. Rein Tollevik Basefarm AS
