Subject [jira] Commented: (NET-326) A KeyManager is required when the protection level is set to 'P' with FTPSClient on active mode
Date Wed, 16 Mar 2011 17:33:29 GMT

    [ https://issues.apache.org/jira/browse/NET-326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13007581#comment-13007581
] 

Sebb commented on NET-326:
--------------------------

I'm still working on this. 

Currently experimenting with a separate KeyManagerUtils class in parallel with the TrustManagerUtils
class.

These can hopefully be used directly with FTPClient using the set???Manager methods.

I've got that mostly working, but there are still some loose ends to tie up. Hopefully in
the next few days.

> 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.
