ldap_simple_bind_s fails intermittently, when run in an loop - openldap-technical

22 Jan 2009


      Hi all,
I am trying to use openldap api's to connect to ldap from my code.
I tried to connect to ldap server 1,00,000 times(just intiliazing ,
binding and unbinding)
Intilaly Binding to the ldap server works fine, but after some time say
after reaching more than 10,000 binds. bind continously fails with below
error .
"Can't connect to the LDAP server - Cannot assign requested address".
  and error number is 91
below is my code snapshot.
int main()
{
    int ret,version,i;
    i=0;
    LDAP  *ld=0;
    while(100000)
    {
        const char *s=0;
        cout<<"count is "<<i++<<endl;
        ld=ldap_init(HOSTNAME,PORTNUMBER);   // HOSTNAME and PORTNUMBER
are defined
        if(ld == NULL)
        {
        cout<<" error in initiliaze "<<endl;
        return 2;
        }
        ret=ldap_simple_bind_s(ld,"","");
        ldap_perror(ld,s);
        if(ret != LDAP_SUCCESS)
        {
        cout<<" error in bin "<<ret<<endl;
        cout<<ldap_err2string(ret)<<" is the error"<<endl;
        }
        else
        {
            cout<<"bind success "<<endl;
        }
        ldap_unbind(ld);
        ld=NULL;
    }
    return 0;
}
i am clue less why this happened.
Is there any restriction or bug (already present) that only certain
number of binds are possible in a given time.
Your help will be highly help full in my further proceedings.
Regards,
Bharath.
