problem using perl-ldap 0.15

[<Sri...@i2...>]

Hi, 
        I am new to perl-ldap and trying to use it to connect to a iplanet 
5.1 directory server. The following code hangs at the bind stage: 

use Net::LDAP;

$ldap = Net::LDAP->new('myhost',port => 389) 
                or die "Can't bind to ldap: $!\n";
$ldap->bind(version => 3); 

I can connect to the directory using Java (JNDI). I have Net::LDAP and 
Convert::ASN installed as specified. Can somebody tell me what could be 
wrong? I am working off a NT 4.0 laptop. 

Any help is appreciated.

Thanks!
