This is the part of the code i’m working with to establish the start tls extended operation. The binding is not working after the execution of start tls.

BerElement *ber;//extended
    struct berval *bv;
    char *retoid;
    struct berval *retdata;
    struct berval oid;

    oid.bv_val=(char*)LDAP_EXOP_START_TLS;
    oid.bv_len=strlen(oid.bv_val);

    ber=ber_alloc_t(LBER_USE_DER);
    cout<<"ber: "<<ber<<"\n";
    ber_printf(ber,"{");
    ber_printf(ber,"tO",LDAP_EXOP_START_TLS,oid);
    ber_printf(ber,"N}");
    res=ber_flatten(ber,&bv);
    ber_free(ber,1);
    cout<<"berf: "<<res<<"\n";

    res=ldap_extended_operation_s(ldap, LDAP_EXOP_START_TLS, bv, NULL, NULL, &retoid, &retdata);
    cout<<res<<"\n";
    
    
    res = ldap_sasl_bind_s();//binds this simple bind is not working with the provided cred after the start tls
    cout<<"bind: "<<res<<"\n";
