попробуй пароль из shаdow взять

что там с htaccess я тоже не знаю, какие-то он сальты странные ставит... для заведения юзеров юзаю програмку:

#include <stdio.h>                                                                            
#include <unistd.h>                                                                          
void main(int argc, char *argv[]) {                                                          
  FILE *handle;                                                                              
  char login[30]={0};                                                                        
  char pass[100]={0};                                                                        
                                                                                              
  if (argc!=2) { fprintf(stderr,"usage: addpass filename\n"); exit(1); }                      
  handle=fopen(argv[1],"a");                                                                  
  if(!handle) { fprintf(stderr,"Can't open %s, aborting\n",argv[1]); }                        
  while (1) {                                                                                
     gets(login);                                                                            
     if(login[0]==0) break;                                                                  
     strcpy(pass,getpass("") );                                                              
     if(feof(stdin)) break;                                                                  
     fprintf(handle,"%s:",login);                                                            
     fprintf(handle,"%s\n",crypt(pass,"aa"));                                                
  }                                                                                          
  fclose(handle);                                                                            
}
