ldap_simple_bind_s fails intermittently, when run in an loop

[<bharath.venkata@wipro.com>]

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.
