Subject [jira] [Commented] (NET-326) A KeyManager is required when the protection level is set to 'P' with FTPSClient on active mode
Date Mon, 21 Mar 2011 13:03:05 GMT

    [ https://issues.apache.org/jira/browse/NET-326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009119#comment-13009119
] 

Bogdan Drozdowski commented on NET-326:
---------------------------------------

Good job. A simple class with a simple API. Different from mine, because it requires an alias
of the certificate to be provided (mine didn't require), but simpler, which is good.

One more thing I've noticed recently: the "S" clients' (SMTPS, POP3S, FTPS) constructors have
an unnecessary line in their javadoc, a leftover after removing the exception description.
Could you fix that?

> Using a simple FTPS client that list a directory, when execPROT("P") is set and the active
mode is on, the following exception is thrown :
> javax.net.ssl.SSLException: No available certificate or key corresponds to the SSL cipher
suites which are enabled.

> This doesn't occur on passive mode.
> The only way to make it work is to set a keyManager although there is no need for a client
authentication.
