JAkub Scholz updated QPID-4875:
-------------------------------

    Description: 
The Java code seems to contain two places where the certificate subjects are 
being parsed. One is used in the client:
{{common/src/main/java/org/apache/qpid/transport/network/security/ssl/SSLUtil.java}}
and the second is used in the broker:
{{broker/src/main/java/org/apache/qpid/server/security/auth/sasl/external/ExternalSaslServer.java}}

Both are actually doing the same - extracting the CN and DC components from the 
subject and creating the username. It should be reconsidered whether we want to 
reuse the SSLUtil functionality from the common part of the code in the broker 
code as well.

However, a bigger problem is that the implementation in both places are not 
working correctly in all situations. One can very easily create a certificate 
with a subject / DN like this:
{{C=CZ,O=Scholz,OU="JAKUB CN=USER1"}}
such certificate actually doesn't contain a CN. But both current 
implementations will still identify the CN as {{USER1"}} in the code. I would 
expect that this will happen only in very rare cases, but it should still be 
handled properly.

However, a bigger problem is that the implementation in both places are not

with a subject / DN like this:
{{C=CR,O=Scholz,OU="JAKUB CN=USER1"}}
such certificate actually doesn't contain a CN. But both current 
implementations will still identify the CN as {{USER1"}} in the code. I would
