Of course, mixing sources can lead to seg faults. Why didn't you compile the whole 2.4.40 release or even better the RE24 git branch? Export the RE24 git branch here: http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=snapshot;h=refs/h… Ciao, Michael.

(ITS#8059) In client code, set option LDAP_OPT_DEBUG_LEVEL LDAP_DEBUG_ANY does not set option.
by peter.driscoll＠dionglobal.com 17 Feb '15

17 Feb '15

Full_Name: Peter John Driscoll Version: openldap-2.4.40 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (203.3.133.17) Set this option does not turn on debugging. #define LDAP_DEBUG_ANY 0xffff const int optionValue = LDAP_DEBUG_ANY; CHECK_RESULT(ldap_set_option(m_ld, LDAP_OPT_DEBUG_LEVEL, &optionValue), "ldap_set_option debug level"); Calling ldap_get_option confirms the change. But in libraries/libldap/sbind.c int ldap_simple_bind_s( LDAP *ld, LDAP_CONST char *dn, LDAP_CONST char *passwd ) The call, Debug( LDAP_DEBUG_TRACE, "ldap_simple_bind_s\n", 0, 0, 0 ); Does not log any debug information, because ldap_debug does not returns 0 instead of 0xFFFF. Debug is defined, #define Debug( level, fmt, arg1, arg2, arg3 ) \ Log3( (level), 0, (fmt), (arg1), (arg2), (arg3) ) #define Log3( level, severity, fmt, arg1, arg2, arg3 ) \ do { \ if ( ldap_debug & (level) ) \ lutil_debug( ldap_debug, (level), (fmt), (arg1), (arg2), (arg3) ); \ } while ( 0 ) #define ldap_debug ((LDAP_INT_GLOBAL_OPT())->ldo_debug) The option is set in, libraries/libldap/options.c int ldap_set_option( LDAP *ld, int option, LDAP_CONST void *invalue) starts with lo = LDAP_INT_GLOBAL_OPT(); but a few lines down, if(ld != NULL) { assert( LDAP_VALID( ld ) ); if( !LDAP_VALID( ld ) ) { return LDAP_OPT_ERROR; } lo = &ld->ld_options; } This code breaks the logic so that the option is not set in the right place. So later in the method, case LDAP_OPT_DEBUG_LEVEL: lo->ldo_debug = * (const int *) invalue; rc = LDAP_OPT_SUCCESS; break; is writing to the wrong place, because lo != LDAP_INT_GLOBAL_OPT() FYI my methods, doing the calling is, void NovaLdap::Connect() { NovaString ldaps = "ldap://"; if (m_SSL) { ldaps = "ldaps://"; } NovaString server = ldaps + m_IpAddress + ":" + ToNovaString(m_IpPort); JOURNAL(SECURITYSERVER,DTL) << "Security Server : Connect " << server << endl; #ifdef _WIN32 m_ld = ldap_sslinit((LDAP_PCHAR) m_IpAddress.data(), m_IpPort, m_SSL); #else CHECK_RESULT(ldap_initialize(&m_ld, server), "ldap_initialize(\2"22 + server + "\")"); #endif JOURNAL(SECURITYSERVER,DTL) << "Security Server : Connected - OK " << endl; if (!m_ld) { JOURNAL(SECURITYSERVER,DTL) << "Security Server : Connect - NULL LD " << endl;D0D throw NovaError(ISSFactory::Error_LDAP_INIT_NULL); } JOURNAL(SECURITYSERVER,DTL) << "Security Server : Connect - set option" << endl; int myVersion =LDAP_VERSION3; CHECK_RESULT(ldap_set_option(m_ld, LDAP_OPT_PROTOCOL_VERSION, &myVersion), "ldap_set_option version"); //CHECK_RESULT(ldap_set_option(m_ld, LDAP_OPT_TLS, &reqcert), "ldap_set_option TLS requires certificate"); #ifdef LDAP_OPT_DEBUG_LEVEL const int optionValue = LDAP_DEBUG_ANY; CHECK_RESULT(ldap_set_option(m_ld, LDAP_OPT_DEBUG_LEVEL, &optionValue), "ldap_set_option debug level"); int optionValueReturned = 0; CHECK_RESULT(ldap_get_option(m_ld, LDAP_OPT_DEBUG_LEVEL, &optionValueReturned), "ldap_set_option debug level"); JOURNAL(SECURITYSERVER,DTL) << "Security Server : Set debug level: " << optionValueReturned << endl; #endif #ifdef LDAP_OPT_CONNECT_ASYNC ldap_set_option( m_ld, LDAP_OPT_CONNECT_ASYNC, LDAP_OPT_OFF ); #endif ldap_set_option(m_ld, LDAP_OPT_REFERRALS, LDAP_OPT_OFF ); ldap_set_option(m_ld, LDAP_OPT_RESTART, LDAP_OPT_ON ); JOURNAL(SECURITYSERVER,DTL) << "Security Server : Connect - OK " << endl; #ifdef _WIN32 CHECK_RESULT(ldap_connect(m_ld, NULL), "ldap_connect"); #endif if (m_StartTLS) { JOURNAL(SECURITYSERVER,DTL) << "Security Server : Connect - Start TLS" << endl; #ifdef _WIN32 CHECK_RESULT(ldap_start_tls_s(m_ld, NULL, NULL, NULL, NULL), "ldap_start_tls_s"); // WINLDAPAPI ULONG LDAPAPI ldap_start_tls_sA ( // IN PLDAP ExternalHandle, // OUT PULONG ServerReturnValue, // OUT LDAPMessage **result, // IN PLDAPControlA *ServerControls, // IN PLDAPControlA *ClientControls // ); #else CHECK_RESULT(ldap_start_tls(m_ld, NULL, NULL, NULL), "ldap_start_tls_s"); #endif } } void NovaLdap::CheckConnection() { JOURNAL(SECURITYSERVER,DTL) << "NovaLdap::CheckConnection: Checking connection" << endl; Connect(); // See if can bind to the DN. if (!m_ServiceAccountUsername.isNull()) { JOURNAL(SECURITYSERVER,DTL) << "Security Server : GetDistinguishedNameForUserName Service service login " << m_ServiceAccountUsername << endl; puts("Security Server : GetDistinguishedNameForUserName Service service login\n"); LDAP_RESULT result = ldap_simple_bind_s(m_ld, (LDAP_PCHAR) m_ServiceAccountUsername.data(), (LDAP_PCHAR) m_ServiceAccountPassword.data()); if (result != (LDAP_RESULT) LDAP_SUCCESS) { NovaString errorMessage(ldap_err2string(result)); throw NovaError(ISSFactory::Error_LDAP_FAILURE, "bind as service user: ", errorMessage); char sevLevel; } ldap_unbind(m_ld); } JOURNAL(SECURITYSERVER,DTL) << "NovaLdap::ececkConnection: Success" << endl; }

(ITS#8058) OpenLDAP: module autogroup (memberof)
by tobias.helfenstein＠wald-rlp.de 15 Feb '15

Full_Name: Tobias Helfenstein Version: 2.4.39 OS: CentOS 7.0 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (87.165.195.65) Hello, we have problems when activating the module autogroup (memberof). We configured the module like the described way in the README file. If we add a new entry to the LDAP tree, the entry is added to the desired group automatically. This is the expected behavior. We can add entries as much as possible and there is no problem. Now, if we delete one of the entries the slapd is very slow and hangs. The action have to be aborted to continue, there is no debug output. Because of that we have to restart the slapd daemon. But the restart takes a long time (3+ minutes). After the restart we can delete only one entry, then the described problem occurs again. We think it is a bug an hope you can help us. Thank you

(ITS#8057) slapo-unique can be bypassed by anyone

Not a gcc bug, the ITS report proved incomplete. gcc-5 inserts "# <file information>" lines (indicating where the macro expansion comes from, I think), so it needs the line breaks. This slightly different test program: #include <db.h> __db_version DB_VERSION_MAJOR+0000; ...produces this: # 2 "test.c" __db_version # 2 "test.c" 3 4 4 # 2 "test.c" +0000; -- Hallvard
