Alex Rudyy updated QPID-8208:
-----------------------------
    Description: 
There is a weakness in Qpid exception handling when communication with external 
services like LDAP. The Broker should take a more defensive approach and handle 
unexpected exceptions thrown by underlying third-party API in addition to 
exceptions declared in API interfaces. The unexpected exceptions thrown by 
underlying API should not affect the stability of the Broker. 

It was reported that on establishment of connection with LDAP using default 
context factory {{com.sun.jndi.ldap.LdapCtxFactory}} the creation of  
{{InitialDirContext}} can end-up in unexpected exception thrown from 
{{com.sun.jndi.ldap.LdapClient}}. It looks like a defect in 
{{com.sun.jndi.ldap.LdapClient}}, but I could not find any existing open bug 
report raised against JVM with similar behaviour. I think that Broker should 
catch unexpected exception, log it and report authentication failure back to 
the client.
