Re: LDAP_OPERATIONS_ERROR :Server encountered an > internal error

[Graham B. <gb...@po...>]

OK, I think I know whats happeneing here.

When the IO error happens Net::LDAP is just returning without
populating the error code in the message object.

So when you call a method like ->code or ->error then $mesg object
will call sync. Which is where it sits and blocks.

Once an error like this happens on the input stream, it is almost
impossible to recover. So Net::LDAP should close the socket, causing
any subsequent request to fail immediately.
