SASL - Digest MD5 - JNDI Help needed

Question

Hi All,
I am using Sunone Directory Server 5.2 and jsdk1.4.1. I tried the Digest-MD5 SASL authentication example given in JNDI tutorial and it worked fine. The problem is , when i try to run the same program thrice or more in succession, it hangs. Actually, the initial context gets created but the operations like simple getAttrs etc does not happen. what could be the problem or rather what is the solution to overcome it.
Attached below is the sample source code used...
try {
Hashtable env = new Hashtable(11);
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost:389/");
env.put(Context.SECURITY_AUTHENTICATION, "DIGEST-MD5");
env.put(Context.SECURITY_PRINCIPAL, "dn:uid=xxx,ou=xxx,dc=xxx,dc=xxx");
env.put(Context.SECURITY_CREDENTIALS, "xxxxx");
System.out.println("about to get context");
DirContext ctx = new InitialDirContext(env);
System.out.println("got context");
Attributes attrs = ctx.getAttributes("ldap://localhost:389", new String[]{"supportedSASLMechanisms"});
System.out.println(attrs);
} catch (NamingException e) {
  e.printStackTrace();
}thanks in advance

Answer 1

As i have metioned , this was the message from the other forum
I have posted the mail correspondences we had (hope they won't consider this as an offence)...
There was a bug in the provider. It has been fixed in 1.4.2 and later
releases.

Hi,
First, I would like to thank everyone behind the
excellent JNDI tutorial. It acted as the bible for my
JNDI learning.
I tried the sample code ServerSasl.java provided. I
got it working after a few trials. I tried to get the
supportedSasl Mechanisms by the Sunone Directory
Server 5.2 . I got them. Then i tried to authenticate
using the default Digest-MD5 (am using jsdk 1.4.1).
When, i try to run the same program in succession, it
hangs up (4 or 5 times in a row). I am getting the
initial context with the credentials provided but it
hangs at doing the simple getAttrs operation. What
could be the problem?
Please reply to this query
thanks in advance
