No, no as easy as with the other synchrounus function calls like
ldap_search_st(), which accept a timeout parameter. You'll have to
implement your own ldap_bind_st() using the asyncrounus function calls:

int ldap_bind_st(LDAP *ld, char *whop, char *credp) {
  int rc, msgid;
  struct timeval tm;
  LDAPMessage *res;
  [...]
  msgid = ldap_bind(ld, whop, credp, LDAP_AUTH_SIMPLE);
  rc = ldap_result(ld, msgid, 1, &tm, &res);
  [...]
}

The API is quite inconsistent here, as there are _st calls for every LDAP
operation except for BIND.

LDAP_OPT_NETWORK_TIMEOUT specifies the maximum time to wait to establish
the TCP connection to the ldap server.
