I am new to C so any guidance will be greatly appreciated.  ldap_simple_bind_s is depricated in favor of ldap_sasl_bind_s.  I need to recompile a program that previously used ldap_simple_bind_s.  The password value is passed to the function that is calling ldap_sasl_bind_s as a char *, but sasl_bind_s is wanting a struct berval.  Do I need to convert it, and if so, how?

LDAP_F( int )
ldap_simple_bind_s LDAP_P(( /* deprecated, use ldap_sasl_bind_s */
        LDAP *ld,
        LDAP_CONST char *who,
        LDAP_CONST char *passwd ));

LDAP_F( int )
ldap_sasl_bind_s LDAP_P((
        LDAP                    *ld,
        LDAP_CONST char *dn,
        LDAP_CONST char *mechanism,
        struct berval   *cred,
        LDAPControl             **serverctrls,
        LDAPControl             **clientctrls,
        struct berval   **servercredp ));

Since a 'strunct berval' is

struct berval {
  unsigned long bv_len;
  char *bv_val;
};

you could use


#include <string.h>

void string_to_berval(const char* pstr, struct berval* pbv) {

  pbv->bv_len = strlen(pstr);
  pbv->bv_val = pstr;
}

//...

char* passwd = "TopSecret";
struct berval bv;

string_to_berval(passwd,&bv);
