ldap_sasl_bind_s

Hi All,

I've been debugging the RealTime Asterisk LDAP driver, namely the function:

static int ldap_reconnect(void) { int bind_result = 0; struct berval cred;

if (ldapConn) { ast_debug(2, "Everything seems fine.\n"); return 1; }

if (ast_strlen_zero(url)) { ast_log(LOG_ERROR, "Not enough parameters to connect to ldap database\n"); return 0; }

if (LDAP_SUCCESS != ldap_initialize(&ldapConn, url)) { ast_log(LOG_ERROR, "Failed to init ldap connection to '%s'. Check debug for more info.\n", url); return 0; }

if (LDAP_OPT_SUCCESS != ldap_set_option(ldapConn, LDAP_OPT_PROTOCOL_VERSION, &version)) { ast_log(LOG_WARNING, "Unable to set LDAP protocol version to %d, falling back to default.\n", version); }

if (!ast_strlen_zero(user)) { ast_debug(2, "bind to '%s' as user '%s'\n", url, user); cred.bv_val = (char *) pass; cred.bv_len = strlen(pass); bind_result = ldap_sasl_bind_s(ldapConn, user, LDAP_SASL_SIMPLE, &cred, NULL, NULL, NULL); } else { ast_debug(2, "bind %s anonymously\n", url); bind_result = ldap_sasl_bind_s(ldapConn, "", LDAP_SASL_SIMPLE, NULL, NULL, NULL, NULL); } if (bind_result == LDAP_SUCCESS) { ast_debug(2, "Successfully connected to database.\n"); connect_time = time(NULL); return 1; } else { ast_log(LOG_WARNING, "bind failed: %s\n", ldap_err2string(bind_result)); ldap_unbind_ext_s(ldapConn, NULL, NULL); ldapConn = NULL; return 0; } }

The line:

bind_result = ldap_sasl_bind_s(ldapConn, NULL, LDAP_SASL_SIMPLE, NULL, NULL, NULL, NULL);

is giving:

May 26 14:52:03 asterisk slapd[30075]: conn=1 fd=12 ACCEPT from IP=127.0.0.1:57926 (IP=0.0.0.0:389) May 26 14:52:03 asterisk slapd[30075]: bind: ber_scanf failed May 26 14:52:03 asterisk slapd[30075]: conn=1 op=0 DISCONNECT tag=120 err=2 text=decoding error May 26 14:52:03 asterisk slapd[30075]: conn=1 fd=12 closed (operations error)

Any debug tips would be greatly appreciated.

Two different libldap have been tested (Centos 5.1 package and Symas OpenLDAP Devel package):

openldap-devel-2.3.27-8.el5_1.3 cdsdevel-3.9-2

Thanks.
