LDAPSSL and seg faults

[Jim Dishaw]

I'm using the Netscape v4.1 C SDK on Solaris 2.8 and I'm having problems
when recovering from a LDAP_SERVER_DOWN error. I have the code shown below
(edited for brevity).  When I get an LDAP_SERVER_DOWN error on the
ldap_search_ext_s() call, the subsequent ldap_simple_bind_s() call causes a
seg fault.  If I don't get the server down error, everything works fine.  I
am doubtful the problem lies in the C SDK since an bug this obvious would
have been caught long ago. Should I be using the reconnect option instead of
unbinding?  Could the problem lie in the directory server not responding to
the unbind call correctly (it is our development LDAP server and is not the
most reliable machine)?  I scanned through the newsgroup, but I could not
find anything.  Any suggestions?  Incidentally, all the calls prior to the
seg fault returned LDAP_SUCCESS.



int connect_server()
{
  if(!init) {
    ldapssl_clientauth_init(...);
    init = 1;
  }

  while(ldptr == NULL) {
    ldptr = ldapssl_init(...);
    ldapssl_enable_clientauth(ldptr, ...);
    ldap_simple_bind_s(ldptr, ...);
  }

  return 1;
}

int search()
{
  int ok;

  do {
    if(!connect_server()) {
      ldap_unbind_s(ldptr);
      ldptr = NULL;
      return 0;
    }
    ldap_search_ext_s(ldptr,...);
    if(LDAP_SERVER_DOWN) {
      ldap_unbind_s(ldptr);
      ldptr = NULL;
      ok = 0;
    } else if(!LDAP_SUCCESS) {
      ldap_unbind_s(ldptr);
      ldptr = NULL;
      return 0;
    } else {
      ....
      ok = 1
    }
  } while(!ok);

  return 1;
}
