Bug in SASL implementation in perl-ldap-0.22

[Simon W. <sx...@sx...>]

There appears to be a bug in Net::LDAP::Bind, with regards to how it passes 
server SASL credentials on to the relevant routines. Both the hash, and
the entry in the hash appear to be wrong.

Currently, $result->{saslCred} is used. I believe this should be replaced with
either 
$bind->{serverSaslCreds} or 
$result->{protocolOp}{bindResponse}{serverSaslCreds}

The attached patch fixes this, I've tested it with a GSSAPI based 
Authen::SASL module to successfully authenticate against OpenLDAP 2.0.7.

Cheers,

Simon
