Setting Timeout for ldap_simple_bind() in SSL mode

Hi,
   
  We are using Netscape 5.12.
  We are facing an issue with ldap_simple_bind() asynchronous call in SSL mode.
  Any help in this matter would be greatly appreciated.
  Is there a way to set a timeout for ldap_simple_bind() asynchronous call (operating 
  in SSL Mode) so that it does not get blocked if LDAP server hanges.
  Currently during the ldap_simple_bind() call, the Netscape SDK seems to do a 
  SSL handshake to exchange messages and due to LDAP server hang,
  the ldap_simple_bind() call hangs.
  Is there a way we can set some timelimit to this function call so that
  we can failover to a different server in such scenarios ?
  It would be great if we can have the control on the client side itself.
  
Following is the stack that we are seeing:
