[horde] more on IMAP authentication problems

[Tucker Bradford]

For those of you sharing my woes, the answer is this. I am using a self 
signed cert... and needed to add

imap/ssl/novalidate-cert

to the line

$conf['auth']['params']['dsn'] = '{hostname/protocol:port}INBOX';

so it would look like this

$conf['auth']['params']['dsn'] = 
'{hostname/imap/ssl/novalidate-cert:993}INBOX';
