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

You're right, the alias could be useful, but it may not always be necessary. I like the current solution of
{code}
keyAlias != null ? keyAlias : findAlias(ks)
{code}
It has both our ideas.

> 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.
